U.S. manufacturers are racing to get into the game while they still can.
In the weird, wide world of energy storage, lithium-ion batteries may appear to be an unshakeably dominant technology. Costs have declined about 97% over the past three decades, grid-scale battery storage is forecast to grow faster than wind or solar in the U.S. in the coming decade, and the global lithium-ion supply chain is far outpacing demand, according to BloombergNEF.
That supply chain, however, is dominated by Chinese manufacturing. According to the International Energy Agency, China controls well over half the world’s lithium processing, nearly 85% of global battery cell production capacity, and the lion’s share of actual lithium-ion battery production. Any country creating products using lithium-ion batteries, including the U.S., is at this point dependent on Chinese imports.
This has, understandably, sent U.S. manufactures searching for alternatives, and lately they have struck on one that has the industry all excited: sodium-ion batteries. As global interest ramps up, domestic manufacturers have at least a prayer of building out their own sodium-ion supply chains before China completely takes over. Research and consulting firm Benchmark Mineral Intelligence expects to see a 350% jump in announced sodium-ion battery manufacturing capacity this year alone. And while the supply of these batteries is only in the tens of gigawatts today, Benchmark forecasts that it will be in the hundreds of gigawatts by 2030.
Sodium-ion technology itself isn’t particularly disruptive — it’s not new, nor does it serve a new market, exactly. It performs roughly the same as lithium-ion in energy storage systems, providing around four hours of power for either grid-scale or residential applications. But sodium-ion chemistries have a handful of key advantages — perhaps most critically that sodium is significantly more abundant in the U.S. than lithium, and is thus far cheaper. China has unsurprisingly taken an early lead in the sodium-ion market anyway, reportedly opening its first sodium-ion battery storage station in May. But because the industry is still so nascent, domestic manufacturers say there’s still time for them to get in the game.
“We’re focused on catching up to China in lithium-ion batteries, where in our view, we should be leapfrogging to what’s next,” Cam Dales, co-founder and chief commercial officer at Peak Energy, a Bay Area-based sodium-ion battery storage startup, told me. “There’s no CATL of the United States. That’s ultimately our ambition, is to become that.”
As political tensions between China and the U.S. mount, relying on a Chinese-dominated battery supply chain is geopolitically risky. Last month, the Biden administration announced a steep increase in tariffs on a wide array of Chinese imports, including a 25% tariff on lithium-ion non-electric vehicle batteries starting in 2026, and another 25% tariff on battery parts and certain critical minerals starting this year.
Because sodium is so plentiful and cheap, companies in the space estimate that sodium-ion storage systems could eventually be around 40% less expensive than lithium-ion systems, once manufacturing scales. This lower price point could eventually make sodium-ion economically viable for storage applications “up to eight, 10, maybe even 12 hours,” Dales told me.
Sodium-ion also has a leg up on lithium-ion when it comes to safety. While this is an ongoing area of research, so far sodium-ion batteries appear less likely to catch fire, at least in part because of their lower energy density and the fact that their electrolytes generally have a higher flashpoint, the temperature at which the liquid is capable of igniting. This could make them safer to install indoors or pack close together. It’s also possible to discharge sodium-ion batteries down to zero volts, completely eliminating the possibility of battery fires during transit, whereas lithium-ion can’t be completely discharged without ruining the battery. Finally, sodium-ion performs better in the cold than lithium-ion batteries, which notoriously struggle to charge and discharge as efficiently at low temperatures.
“When we saw announcements coming out of China about very large investments in large capacity sodium projects, that was really an eye opener for us,” Dales told me. He and co-founder Landon Mossburg launched Peak Energy last year with $10 million in funding. The company is currently importing sodium-ion cells and assembling battery packs domestically, but by 2027, Dales said he hopes to produce both cells and packs in the U.S., with an eye toward opening a gigafactory and onshoring the entirety of the supply chain.
He’s not alone in this ambition. Natron Energy, another Silicon Valley-based sodium-ion company, has been at this for more than a decade. The startup, founded in 2012, recently opened the first commercial-scale sodium-ion battery manufacturing facility in the U.S. When fully ramped, the plant will have the capacity to produce 600 megawatts of batteries annually, paving the way for future gigawatt-scale facilities.
It cost Natron over $40 million to upgrade the Michigan-based plant, which formerly produced lithium-ion batteries, into a sodium-ion facility, and while the first shipments were expected to begin in June, none have yet been announced. The company’s backers include Khosla Ventures as well as strategic investors such as Chevron, which is interested in using this tech at EV charging stations; United Airlines, which hopes to use it for charging motorized ground equipment; and Nabor Industries, one of the world’s largest oil and gas drilling companies, which is interested in using sodium-ion batteries to power drilling rigs. It also received nearly $20 million from ARPA-E to fund the conversion of the Michigan facility.
Beyond the U.S. and China, France-based sodium-ion cell developer Tiamat is planning to build out a massive 5-gigawatt facility, while Sweden-based Northvolt and UK-based Faradion are also hoping to bring sodium-ion battery manufacturing to the European market.
Sodium-ion isn’t a magic bullet technology, though, and it certainly won’t make sense for all applications. The main reason there hasn’t been much interest up until now is because these batteries are about 30% less energy-dense than their lithium-ion counterparts. That likely doesn’t matter too much for grid-scale or even residential storage systems, where there’s usually enough open land, garage, or exterior wall space to install a sufficiently-sized system. But it is the reason why sodium-ion wasn’t commercialized sooner, as lithium-ion’s space efficiency is better suited to the portable electronics and electric vehicle markets.
“It’s only in the last two years probably, that the stationary storage market has gotten big enough where it alone can drive specific chemistries and the investment required to scale them,” Dales told me.
Catherine Peake, an analyst at Benchmark Mineral Intelligence, also told me that lithium iron phosphate batteries — the specific flavor of lithium-ion that’s generally favored for energy storage systems — usually have a longer cycle life than sodium-ion batteries, meaning they can charge and discharge more times before performance degrades. “That cycle life is actually a pretty key metric for [energy storage system] applications,” she said, though she acknowledged that Natron is an outlier in this regard, as the company claims to have a longer cycle life than standard lithium-ion batteries.
Lithium is also a volatile market. Though prices have bottomed out recently, less than two years ago the world was facing the opposite scenario, as China saw the price for battery-grade lithium carbonate hit an all-time high, Kevin Shang, a senior research analyst at the energy consultancy WoodMackenzie, told me. “So this catalyzed a soaring interest in sodium-ion batteries,” he said.
Although Shang and Peake agree that the U.S. could seize this moment to build a domestic sodium-ion supply chain, both also said that scaling production up to the level of China or other battery giants like South Korea or Japan is a longshot. “After all, they have been doing this battery-related business for over 10 years. They have more experience in scaling up these materials, in scaling up these technologies,” Shang told me.
These countries are home to the world’s largest battery manufacturers, with CATL and BYD in China and LG Energy in South Korea. But Natron and Peak Energy are both startups, lacking the billions that would allow for massive scale-up, at least in the short term.
“It shouldn't be underestimated how hard it is to make anything in large volume,” Matt Stock, a product director at Benchmark, told me.Largely due to the maturity of lithium-ion battery supply chains, the research firm doesn’t see sodium-ion becoming the dominant energy storage tech anytime soon. Rather, by 2030, Benchmark forecasts that sodium-ion batteries will comprise 5% of the battery energy storage market, increasing to over 10% by 2040. BloombergNEF is somewhat more optimistic, predicting sodium-ion will make up 12% of the stationary energy storage market by 2030.
And while storage may be the most obvious near-term use case for sodium-ion batteries, it’s certainly not the only industry that stands to benefit. China is experimenting with using these batteries in two- and three-wheeled vehicles such as electric scooters, bikes, and motorcycles. And as the tech improves, Stock said it’s possible that sodium-ion batteries could become a viable option for longer-range EVs as well.
Ultimately, Dales thinks these batteries will follow a similar technological trajectory to lithium iron phosphate, a chemistry that many in the west thought would never be suitable for use in electric vehicle batteries. “Over time, our view is that sodium-ion will continue to increase its energy density just like [lithium iron phosphate] did,” Dales told me. Now, lithium iron phosphate is the dominant battery chemistry for Chinese-made EVs. “But what actually happened was it was so cheap and they made it better and better and better than now it’s taking over the world. We see this playing out again with sodium-ion.”
Benchmark, on the other hand, is more circumspect regarding sodium-ion’s world dominating potential. Stock said he sees the technology more as a supplement to lithium-ion, which can swoop in when lithium prices boom or critical minerals shortages hit. “When that happens, something like sodium-ion can fill the space. And that’s really where it’s a complementary technology rather than a replacement,” he told me. “If there were other technologies as mature as sodium-ion, we’d also see those being scaled alongside it, but sodium-ion is kind of next in line.”

Businesses were already bracing for a crash. Then came another 50% tariff on Chinese goods.
When I wrote Heatmap’s guide to driving less last year, I didn’t anticipate that a good motivation for doing so would be that every car in America was about to get a lot more expensive.
Then again, no one saw the breadth and depth of the Trump administration’s tariffs coming. “We would characterize this slate of tariffs as ‘worse than the worst case scenario,’” one group of veteran securities analysts wrote in a note to investors last week, a sentiment echoed across Wall Street and reflected in four days of stock market turmoil so far.
But if the economic downturn has renewed your interest in purchasing a bike or e-bike, you’ll want to act fast — and it may already be too late. Because Trump’s “Liberation Day” tariffs stack on top of his other tariffs and duties, the U.S. bicycle trade association PeopleForBikes calculated that beginning on April 9, the day the newest tariffs come into effect, the duty on e-bikes from China would be 79%, up from nothing at all under President Biden. The tariff on most non-electric bikes from China, meanwhile, would spike to 90%, up from 11% on January 1 of this year. Then on Tuesday, the White House announced that it would add another 50% tariff on China on top of that whole tariff stack, starting Wednesday, in retaliation for Beijing’s counter-tariffs.
Prior to the latest announcement, Jay Townley, a founding partner of the cycling industry consulting firm Human Powered Solutions, had told me that if the Trump administration actually followed through on a retaliatory 50% tariff on top of those duties, then “we’re out of business because nobody can afford to bring in a bicycle product at 100% or more in tariffs.”
It’s difficult to overstate how existential the tariffs are for the bicycle industry. Imports account for 97% of the bikes purchased in the United States, of which 87% come from China, making it “one of the most import-dependent and China-dependent industries in the U.S.,” according to a 2021 analysis by the Coalition for a Prosperous America, which advocates for trade-protectionist policies.
Many U.S. cycling brands have grumbled for years about America’s relatively generous de minimis exemption, a policy of waiving duties on items valued at less than $800. The loophole — which is what enables shoppers to buy dirt-cheap clothes from brands like Temu, Shein, and Alibaba — has also allowed for uncertified helmets and non-compliant e-bikes and e-bike batteries to flood the U.S. market. These batteries, which are often falsely marketed as meeting international safety standards, have been responsible for deadly e-bike fires in places like New York City. “A going retail for a good lithium-ion replacement battery for an e-bike is $800 to $1,000,” Townley said. “You look online, and you’ll see batteries at $350, $400, that come direct to you from China under the de minimis exemption.”
Cyclingnews reported recently that Robert Margevicius, the executive vice president of the American bicycle giant Specialized, had filed a complaint with the Trump administration over losing “billions in collectable tariffs” through the loophole. A spokesperson for Specialized defended Margevicius’ comment by calling it an “industry-wide position that is aligned with PeopleForBikes.” (Specialized did not respond to a request for clarification from Heatmap, though a spokesperson told Cyclingnews that de minimis imports permit “unsafe products and intellectual property violation.” PeopleForBikes’ general and policy counsel Matt Moore told me in an email that “we have supported reforming the way the U.S. treats low-value de minimis imports for several years.”)
Trump indeed axed China’s de minimis exemption as part of his April 2 tariffs — a small win for the U.S. bicycle brands. But any protection afforded by duties on cheap imported bikes and e-bikes will be erased by the damage from high tariffs imposed on China and other Asian countries. Fewer than 500,000 bicycles in a 10 million-unit market are even assembled in the United States, and essentially none is entirely manufactured here. “We do not know how to make a bike,” Townley told me flatly. Though a number of major U.S. brands employ engineers to design their bikes, when it comes to home-shoring manufacturing, “all of that knowledge resides in Taiwan, China, Vietnam. It isn’t here.”
In recent years, Chinese factories had become “very proficient at shipping goods from third-party countries” in order to avoid European anti-dumping duties, as well as leftover tariffs from Trump’s first term, Rick Vosper, an industry veteran and columnist at Bicycle Retailer and Industry News, told me. “Many Chinese companies built bicycle assembly plants in Vietnam specifically so the sourcing sticker would not say ‘made in China,’” he added. Of course, those bikes and component parts are now also subject to Trump’s tariffs, which are as high as 57% for Vietnam, 60% for Cambodia, and 43% for Taiwan for most bikes. (A potential added tariff on countries that import oil from Venezuela could bump them even higher.)
The tariffs could not come at a worse time for the industry. 2019 marked one of the slowest years for the U.S. specialty retail bike business in two decades, so when COVID hit — and suddenly everyone wanted a bicycle as a way of exercising and getting around — there was “no inventory to be had, but a huge influx of customers,” Vosper told me. In response, “major players put in huge increases in their orders.”
But by 2023, the COVID-induced demand had evaporated, leaving suppliers with hundreds of millions of dollars in inventory that they couldn’t move. Even by discounting wholesale prices below their own cost to make the product and offering buy-one-get-one deals, dealers couldn’t get the bikes off their hands. “All the people who wanted to buy a bike during COVID have bought a bike and are not ready to buy another one anytime soon,” Vosper said.
Going into 2025, many retailers were still dealing with the COVID-induced bicycle glut; Mike Blok, the founder of Brooklyn Carbon Bike Company in New York City, told me he could think of three or four tristate-area shops off the top of his head that have closed in recent months because they were sitting on inventory.
Blok, however, was cautiously optimistic about his own position. While he stressed that he isn’t a fan of the tariffs, he also largely sells pre-owned bikes. On the low end of the market, the tariffs will likely raise prices no more than about $15 or $20, which might not make much of a difference to consumer behavior. But for something like a higher-end carbon fiber bike, which can run $2,700 or higher and is almost entirely produced in Taiwan, the tariffs could mean an increase of hundreds of dollars for customers. “I think what that will mean for me is that more folks will be open to the pre-owned option,” Blok said, although he also anticipates his input costs for repairs and tuning will go up.
But there’s a bigger, and perhaps even more obvious, problem for bike retailers beyond their products becoming more expensive. “What I sell is not a staple good; people don’t need a bike,” Blok reminded me. “So as folks’ discretionary income diminishes because other things become more expensive, they’ll have less to spend on discretionary items.”
Townley, the industry consultant, confirmed that many major cycling brands had already seen the writing on the wall before Trump announced his tariffs and begun to pivot to re-sale. Bicycling Magazine, a hobbyist publication, is even promoting “buying used” as one of its “tips to help you save” under Trump’s tariffs. Savvy retailers might be able to pivot and rely on their service, customer loyalty, and re-sale businesses to stay afloat during the hard days ahead; Moore of PeopleForBikes also noted that “repair services may increase” as people look to fix what they already have.
And if you don’t have a bike or e-bike but were thinking about getting one as a way to lighten your car dependency, decarbonize your life, or just because they’re cool, “there are still good values to be found,” Moore went on. “Now is a great time to avoid a likely increase in prices.” Townley anticipated that depending on inventory, we’re likely 30 to 40 days away from seeing prices go up.
In the meantime, cycling organizations are scrambling to keep their members abreast of the coming changes. “PeopleForBikes is encouraging our members to contact their elected representatives about the very real impacts these tariffs will have on their companies and our industry,” Moore told me. The National Bicycle Dealers Association, a nonprofit supporting specialty bicycle retailers, has teamed up with the D.C.-based League of American Bicyclists, a ridership organization, to explore lobbying lawmakers for the first time in decades in the hopes that some might oppose the tariffs or explore carve-outs for the industry.
But Townley, whose firm Human Powered Solutions is assisting in NBDA’s effort, shared a grim conversation he had at a recent trade show in Las Vegas, where a new board member at a cycling organization had asked him “what can we do” about Trump’s tariffs.
“I said, ‘You’re out of time,” Townley recalled. “There isn’t much that can be done. All we can do is react.”
Any household savings will barely make a dent in the added costs from Trump’s many tariffs.
Donald Trump’s tariffs — the “fentanyl” levies on Canada, China, and Mexico, the “reciprocal” tariffs on nearly every country (and some uninhabited islands), and the global 10% tariff — will almost certainly cause consumer goods on average to get more expensive. The Yale Budget Lab estimates that in combination, the tariffs Trump has announced so far in his second term will cause prices to rise 2.3%, reducing purchasing power by $3,800 per year per household.
But there’s one very important consumer good that seems due to decline in price.
Trump administration officials — including the president himself — have touted cheaper oil to suggest that the economic response to the tariffs hasn’t been all bad. On Sunday, Secretary of the Treasury Scott Bessent told NBC, “Oil prices went down almost 15% in two days, which impacts working Americans much more than the stock market does.”
Trump picked up this line on Truth Social Monday morning. “Oil prices are down, interest rates are down (the slow moving Fed should cut rates!), food prices are down, there is NO INFLATION,” he wrote. He then spent the day posting quotes from Fox Business commentators echoing that idea, first Maria Bartiromo (“Rates are plummeting, oil prices are plummeting, deregulation is happening. President Trump is not going to bend”) then Charles Payne (“What we’re not talking about is, oil was $76, now it’s $65. Gasoline prices are going to plummet”).
But according to Neil Dutta, head of economic research at Renaissance Macro Research, pointing to falling oil prices as a stimulus is just another example of the “4D chess” theory, under which some market participants attribute motives to Trump’s trade policy beyond his stated goal of reducing trade deficits to as near zero (or surplus!) as possible.
Instead, oil markets are primarily “responding to the recession risk that comes from the tariff and the trade war,” Dutta told me. “That is the main story.” In short, oil markets see less global trade and less global production, and therefore falling demand for oil. The effect on household consumption, he said, was a “second order effect.”
It is true that falling oil prices will help “stabilize consumption,” Dutta told me (although they could also devastate America’s own oil industry). “It helps. It’ll provide some lift to real income growth for consumers, because they’re not spending as much on gasoline.” But “to fully offset the trade war effects, you basically need to get oil down to zero.”
That’s confirmed by some simple and extremely back of the envelope math. In 2023, households on average consumed about 700 gallons of gasoline per year, based on Energy Information Administration calculations that the average gasoline price in 2023 was $3.52, while the Bureau of Labor Statistics put average household gasoline expenditures at about $2,450.
Let’s generously assume that due to the tariffs and Trump’s regulatory and diplomatic efforts, gas prices drop from the $3.26 they were at on Monday, according to AAA, to $2.60, the average price in 2019. (GasBuddy petroleum analyst Patrick De Haanwrote Monday that the tariffs combined with OPEC+ production hikes could lead gas prices “to fall below $3 per gallon.”)
Let’s also assume that this drop in gas prices does not cause people to drive more or buy less fuel-efficient vehicles. In that case, those same 700 gallons cost the average American $1,820, which would generate annual savings of $630 on average per household. If we went to the lowest price since the Russian invasion of Ukraine, about $3 per gallon, total consumption of 700 gallons would cost a household about $2,100, saving $350 per household per year.
That being said, $1,820 is a pretty low level for annual gasoline consumption. In 2021, as the economy was recovering from the Covid recession and before gas prices popped, annual gasoline expenditures only got as low as $1,948; in 2020 — when oil prices dropped to literally negative dollars per barrel and gas prices got down to $1.85 a gallon — annual expenditures were just over $1,500.
In any case, if you remember the opening paragraphs of this story, even the most generous estimated savings would go nowhere near surmounting the overall rise in prices forecast by the Yale Budget Lab. $630 is less than $3,800! (JPMorgan has forecast a more mild increase in prices of 1% to 1.5%, but agrees that prices will likely rise and purchasing power will decline.)
But maybe look at it this way: You might be able to drive a little more than you expected to, even as your costs elsewhere are going up. Just please be careful! You don’t want to get into a bad accident and have to replace your car: New car prices are expected to rise by several thousand dollars due to Trump’s tariffs.
With cars about to get more expensive, it might be time to start tinkering.
More than a decade ago, when I was a young editor at Popular Mechanics, we got a Nissan Leaf. It was a big deal. The magazine had always kept long-term test cars to give readers a full report of how they drove over weeks and months. A true test of the first true production electric vehicle from a major car company felt like a watershed moment: The future was finally beginning. They even installed a destination charger in the basement of the Hearst Corporation’s Manhattan skyscraper.
That Leaf was a bit of a lump, aesthetically and mechanically. It looked like a potato, got about 100 miles of range, and delivered only 110 horsepower or so via its electric motors. This made the O.G. Leaf a scapegoat for Top Gear-style car enthusiasts eager to slander EVs as low-testosterone automobiles of the meek, forced upon an unwilling population of drivers. Once the rise of Tesla in the 2010s had smashed that paradigm and led lots of people to see electric vehicles as sexy and powerful, the original Leaf faded from the public imagination, a relic of the earliest days of the new EV revolution.
Yet lots of those cars are still around. I see a few prowling my workplace parking garage or roaming the streets of Los Angeles. With the faded performance of their old batteries, these long-running EVs aren’t good for much but short-distance city driving. Ignore the outdated battery pack for a second, though, and what surrounds that unit is a perfectly serviceable EV.
That’s exactly what a new brand of EV restorers see. Last week, car site The Autopiancovered DIYers who are scooping up cheap old Leafs, some costing as little as $3,000, and swapping in affordable Chinese-made 62 kilowatt-hour battery units in place of the original 24 kilowatt-hour units to instantly boost the car’s range to about 250 miles. One restorer bought a new battery on the Chinese site Alibaba for $6,000 ($4,500, plus $1,500 to ship that beast across the sea).
The possibility of the (relatively) simple battery swap is a longtime EV owner’s daydream. In the earlier days of the electrification race, many manufacturers and drivers saw simple and quick battery exchange as the solution for EV road-tripping. Instead of waiting half an hour for a battery to recharge, you’d swap your depleted unit for a fully charged one and be on your way. Even Tesla tested this approach last decade before settling for good on the Supercharger network of fast-charging stations.
There are still companies experimenting with battery swaps, but this technology lost. Other EV startups and legacy car companies that followed Nissan and Tesla into making production EVs embraced the rechargeable lithium-ion battery that is meant to be refilled at a fast-charging station and is not designed to be easily removed from the vehicle. Buy an electric vehicle and you’re buying a big battery with a long warranty but no clear plan for replacement. The companies imagine their EVs as something like a smartphone: It’s far from impossible to replace the battery and give the car a new life, but most people won’t bother and will simply move on to a new car when they can’t take the limitations of their old one anymore.
I think about this impasse a lot. My 2019 Tesla Model 3 began its life with a nominal 240 miles of range. Now that the vehicle has nearly six years and 70,000 miles on it, its maximum range is down to just 200, while its functional range at highway speed is much less than that. I don’t want to sink money into another vehicle, which means living with an EV’s range that diminishes as the years go by.
But what if, one day, I replaced its battery? Even if it costs thousands of dollars to achieve, a big range boost via a new battery would make an older EV feel new again, and at a cost that’s still far less than financing a whole new car. The thought is even more compelling in the age of Trump-imposed tariffs that will raise already-expensive new vehicles to a place that’s simply out of reach for many people (though new battery units will be heavily tariffed, too).
This is no simple weekend task. Car enthusiasts have been swapping parts and modifying gas-burning vehicles since the dawn of the automotive age, but modern EVs aren’t exactly made with the garage mechanic in mind. Because so few EVs are on the road, there is a dearth of qualified mechanics and not a huge population of people with the savvy to conduct major surgery on an electric car without electrocuting themselves. A battery-replacing owner would need to acquire not only the correct pack but also potentially adapters and other equipment necessary to make the new battery play nice with the older car. Some Nissan Leaf modifiers are finding their replacement packs aren’t exactly the same size, shape or weight, The Autopian says, meaning they need things like spacers to make the battery sit in just the right place.
A new battery isn’t a fix-all either. The motors and other electrical components wear down and will need to be replaced eventually, too. A man in Norway who drove his Tesla more than a million miles has replaced at least four battery packs and 14 motors, turning his EV into a sort of car of Theseus.
Crucially, though, EVs are much simpler, mechanically, than combustion-powered cars, what with the latter’s belts and spark plugs and thousands of moving parts. The car that surrounds a depleted battery pack might be in perfectly good shape to keep on running for thousands of miles to come if the owner were to install a new unit, one that could potentially give the EV more driving range than it had when it was new.
The battery swap is still the domain of serious top-tier DIYers, and not for the mildly interested or faint of heart. But it is a sign of things to come. A market for very affordable used Teslas is booming as owners ditch their cars at any cost to distance themselves from Elon Musk. Old Leafs, Chevy Bolts and other EVs from the 2010s can be had for cheap. The generation of early vehicles that came with an unacceptably low 100 to 150 miles of range would look a lot more enticing if you imagine today’s battery packs swapped into them. The possibility of a like-new old EV will look more and more promising, especially as millions of Americans realize they can no longer afford a new car.
