Wanted: EV batteries, dead or alive
Battery recycling is one way to secure critical minerals for electric vehicles without getting caught up in geopolitics, but it's not going to break the U.S. of its dependence on China any time soon.
Why it matters: In order to produce new batteries with recycled minerals, you need to collect enough dead batteries to extract those materials.
Most electric vehicles haven't been around long enough to reach the end of their lives.
Plus, it turns out that EV batteries last much longer than anyone expected.
While EV manufacturers typically guarantee the battery for at least eight years or 100,000 miles, evidence shows they'll last as long as 15 or 20 years, according to Recurrent, which tracks EV resale values.
The big picture: A closed-loop supply of recycled battery materials would eliminate the need for additional mining or foreign minerals.
Redwood Materials is the leader among a handful of companies trying to build that battery ecosystem.
How it works: Redwood takes in batteries from used EVs, as well as phones, electronics and scrap from battery factories.
Some batteries still have enough life to be remanufactured or reused, such as for backup power at data centers, while others are ready to be recycled.
Redwood recovers more than 95% of the critical minerals inside — like lithium, cobalt, nickel, and copper — and returns them to the supply chain.
Last year, it recycled more than 20 GWh of lithium-ion batteries, enough to power 250,000 new EVs.
Yes, but: While Redwood has multi-billion-dollar deals with Toyota and Panasonic to buy its recycled materials, the envisioned market doesn't quite exist yet.
Most of Redwood's $200 million in revenue last year came from selling minerals for other purposes like fertilizer or computer processors.
By early next year, it will begin scaling up production of recycled cathode active material that Toyota, Panasonic and other customers will eventually use to manufacture new batteries.
What they're saying: Already, Redwood is taking in more materials for recycling than it expected, says Dustin Krause, vice president of business development.
"There's no concern on our side that there's going to be a shortage of material," he tells Axios. "It's going to grow very rapidly."
Here's how Redwood expects things to play out:

This Might Be Nissan's New Sedan Before You're Supposed to See It
Update: This story has been updated with more information regarding Nissan's EV concept in China. Nissan has a massive product onslaught planned over the next few years. Alongside the latest Kicks and the updated Murano SUVs, the Japanese automaker has a new Leaf coming to the US as early as next year. But if these patent filings are any indication, there could be even more products on the horizon—and soon. Nissan recently filed a patent with the World Intellectual Property Organization, as uncovered by Top Gear Philippines . The patent was filed in China on September 14 of last year and officially registered on May 9, 2025. It shows an updated Nissan sedan with the brand's latest design language. Nissan Patent Images Photo by: WIPO It's unclear whether these images show a new Sentra, Altima, Maxima, or something different entirely. The photos look nearly identical to the Evo concept from earlier last year, though they weren't officially filed until after that concept debuted. It could potentially be a production version of that vehicle. The patent also bears a similar resemblance to the Chinese Nissan N7 , but that sedan is larger and has more distinct cues. If this is a US-bound model, our best guess would be all-new Sentra or a revived Altima, which may be discontinued in the US after this year. The front fascia bears the automaker's new angular headlight treatment, which we've seen on the upcoming Leaf and a few of Nissan's previous concepts. The back end, meanwhile, has a slim light bar that encircles the trunk lid and stretches out to the rear bumper on either side. The profile almost makes it look like a fastback, which leads us to believe this is a mid-size sedan as opposed to a compact. We've seen spy photos of Nissan testing a sedan prototype in Michigan that looks nearly identical to the patent images pictured here. But even in those spy photos, it's difficult to tell if the car in question is the smaller Sentra or the mid-size Altima. Our spy photographers believe it could be the Sentra, but slightly larger than the current-generation model. Photo by: WIPO Photo by: WIPO In those spy photos, we also see an exhaust system, which means Nissan won't go full EV for its next sedan. Our best guess is a new hybrid system, potentially the turbocharged 1.5-liter hybrid unit from the plug-in-hybrid Frontier —which won't come to the US. That powertrain delivers 402 horsepower in the plug-in truck, but a detuned version of that could make sense in the smaller Sentra or Altima sedans. If this is indeed a new Sentra, don't expect to see a production version before 2027. The current model is still on sale in the US, and it likely won't change for 2026. With the Altima rumored to be discontinued after this year, we could see a new version of that sedan before the end of 2025. If we're lucky.

Why These Analysts Are Still Bullish on Tesla Despite Musk-Trump Spat
Tesla CEO Elon Musk and President Donald Trump's public spat rattled Tesla shares this week, but several Wall Street analysts said they're still bullish on the stock. Analysts from Wedbush and Morgan Stanley said their long-term views on Tesla's potential were not substantially changed by the dispute. However, Wedbush said the fallout could make Tesla's regulatory path more (TSLA) CEO Elon Musk and President Donald Trump's public feud rattled Tesla shares this week, but several Wall Street analysts said they're still bullish on the stock. Wedbush analysts led by Dan Ives, with a $500 price target leading Wall Street analysts tracked by Visible Alpha, called the back-and-forth "jaw dropping and a shock to the market," but said the "feud does not change our bullish view of Tesla and the autonomous view." However, they said it could "put a fly in the ointment" regarding earlier expectations that Musk and Trump's relationship could ease the regulatory path for Tesla to get approvals for its self-driving software and other products. Tesla remains a stock that has divided analysts, with 10 of those tracked by Visible Alpha issuing "buy" ratings, while four have "hold," and four have "sell" ratings. Their price targets range from as low as $120, implying a roughly 60% drop from Friday's intraday level, to Wedbush's $500 at the higher end. The stock was up 6% around $301 in recent trading, after tumbling 14% Thursday. Morgan Stanley analysts, with a $410 price target, said the deteriorating relationship between Musk and Trump could further dent Tesla's sales as it "could potentially (temporarily) alienate multiple sides of the political spectrum." Still, they added they're "not convinced the longer-term vectors that drive the stock's value have changed here," pointing to Tesla's leadership in robotics, autonomous driving, and artificial intelligence technology. Oppenheimer analysts were more cautious, saying the "difficult work at TSLA is just beginning as the company starts to repair brand damage while executing on its Physical AI strategy." Ahead of the EV maker's expected launch of its robotaxi service next week, the analysts said they "continue to see challenges in TSLA's autonomy platform," as issues could arise with its cameras or software. Tesla shares were among the biggest gainers on the S&P 500 on Friday, winning back some of Thursday's losses. They've lost about one-quarter of their value since the start of the year, with Thursday's drop knocking Tesla out of the $1 trillion market cap club.

U.S. declares Biden fuel economy rules exceeded legal authority
WASHINGTON — The Transportation Department on June 6 declared that fuel economy rules issued under then President Joe Biden exceeded the government's legal authority by including electric vehicles in setting the rules, automaker officials said.T The department made the declaration as it published a final 'Resetting the Corporate Average Fuel Economy Program' rule. Removing EVs from the calculations for credits and the regulatory mandates will likely result in lower overall fuel economy requirements. A future separate rule from the administration of President Donald Trump will revise the specific fuel economy requirements. Senate Republicans on June 5 proposed eliminating fines for automakers who fail to meet Corporate Average Fuel Economy rules as part of a wide-ranging tax bill, a boost to Detroit automakers selling gasoline-powered vehicles. Sign up for our daily First Shift morning newscast email for a quick video to start your day. Last year, Chrysler parent Stellantis paid $190.7 million in civil penalties for failing to meet U.S. fuel economy requirements for 2019 and 2020 after paying nearly $400 million for penalties from 2016 through 2019. General Motors previously paid $128.2 million in penalties for 2016 and 2017. Thursday's proposal also makes emissions credits sold by Tesla Inc. less valuable as rivals won't have to pay Tesla to meet requirements. The lawmakers estimated it would save automakers $200 million. GM and Chrysler did not immediately comment. U.S. House Republicans are pursuing similar aims but with a different approach. Last month they proposed repealing planned hikes in fuel economy requirements as well as vehicle emissions rules adopted under the Biden administration. The House bill would also kill a $7,500 tax credit for new electric vehicles, impose a new $250 annual fee on EVs for road repair costs and would phase out EV battery production tax credits in 2028. The two chambers have also voted to bar California's landmark plan to end the sale of gasoline-only vehicles by 2035 which has been adopted by 11 other states representing a third of the U.S. auto market. That bill is currently awaiting President Donald Trump's signature. The Transportation Department is expected to declare that fuel economy rules issued under Biden exceeded the government's legal authority by including EVs. Last year, the National Highway Traffic Safety Administration said it would hike fuel economy rules to an average of 50.4 miles per gallon by 2031 — up from 39.1 mpg for light-duty vehicles. It warned the auto industry collectively was expected to face a total of $1.83 billion in fines through 2031. Have an opinion about this story? Tell us about it and we may publish it in print.
