The EV Battery Tech That’s Worth the Hype, According to Experts


You’ve seen the headlines: This battery breakthrough is going to change the electric vehicle forever. And then … silence. You head to the local showroom, and the cars all kind of look and feel the same.

WIRED got annoyed about this phenomenon. So we talked to battery technology experts about what’s really going on in electric vehicle batteries. Which technologies are here? Which will be, probably, but aren’t yet, so don’t hold your breath? What’s probably not coming anytime soon?

“It’s easy to get excited about these things, because batteries are so complex,” says Pranav Jaswani, a technology analyst at IDTechEx, a market intelligence firm. “Many little things are going to have such a big effect.” That’s why so many companies, including automakers, their suppliers, and battery-makers, are experimenting with so many bit parts of the battery. Swap one electrical conductor material for another, and an electric vehicle battery’s range might increase by 50 miles. Rejigger how battery packs are put together, and an automaker might bring down manufacturing costs enough to give consumers a break on the sales lot.

Still, experts say, it can take a long time to get even small tweaks into production cars—sometimes 10 years or more. “Obviously, we want to make sure that whatever we put in an EV works well and it passes safety standards,” says Evelina Stoikou, who leads the battery technology and supply chain team at BloombergNEF, a research firm. Ensuring that means scientists coming up with new ideas, and suppliers figuring out how to execute them; the automakers, in turn, rigorously test each iteration. All the while, everyone’s asking the most important question: Does this improvement make financial sense?

So it’s only logical that not every breakthrough in the lab makes it to the road. Here are the ones that really count—and the ones that haven’t quite panned out, at least so far.

It’s Really Happening

The big deal battery breakthroughs all have something in common: They’re related to the lithium-ion battery. Other battery chemistries are out there—more on them later—but in the next decade, it’s going to be hard to catch up with the dominant battery form. “Lithium-ion is already very mature,” says Stoikou. Lots of players have invested big money in the technology, so “any new one is going to have to compete with the status quo.”

Lithium Iron Phosphate

Why it’s exciting: LFP batteries use iron and phosphate instead of pricier and harder-to-source nickel and cobalt, which are found in conventional lithium-ion batteries. They’re also more stable and slower to degrade after multiple charges. The upshot: LFP batteries can help bring down the cost of manufacturing an EV, an especially important data point while Western electrics struggle to compete, cost-wise, with conventional gas-powered cars. LFP batteries are already common in China, and they’re set to become more popular in European and American electric vehicles in the coming years.

Why it’s hard: LFP is less energy dense than alternatives, meaning you can’t pack as much charge—or range—into each battery.

More Nickel

Why it’s exciting: The increased nickel content in lithium nickel manganese cobalt batteries ups the energy density, meaning more range in a battery pack without much more size or weight. Also, more nickel can mean less cobalt, a metal that’s both expensive and ethically dubious to obtain.

Why it’s hard: Batteries with higher nickel content are potentially less stable, which means they carry a higher risk of cracking or thermal runaway—fires. This means battery-makers experimenting with different nickel content have to spend more time and energy on the careful design of their products. That extra fussiness means more expense. For this reason, expect to see more nickel use in batteries for higher-end EVs.

Dry Electrode Process

Why it’s exciting: Usually, battery electrodes are made by mixing materials into a solvent slurry, which then is applied to a metal current collector foil, dried, and pressed. The dry electrode process cuts down on the solvents by mixing the materials in dry powder form before application and lamination. Less solvent means fewer environmental and health and safety concerns. And getting rid of the drying process can save production time—and up efficiency—while reducing the physical footprint needed to manufacture batteries. This all can lead to cheaper manufacturing, “which should trickle down to make a cheaper car,” says Jaswani. Tesla has already incorporated a dry anode process into its battery-making. (The anode is the negative electrode that stores lithium ions while a battery is charging.) LG and Samsung SGI are also working on pilot production lines.

Why it’s hard: Using dry powders can be more technically complicated.

Cell-to-Pack

Why it’s exciting: In your standard electric vehicle battery, individual battery cells get grouped into modules, which are then assembled into packs. Not so in cell-to-pack, which puts cells directly into a pack structure without the middle module step. This lets battery-makers fit more battery into the same space, and can lead to some 50 additional miles of range and higher top speeds, says Jaswani. It also brings down manufacturing costs, savings that can be passed down to the car buyer. Big-time automakers including Tesla and BYD, plus Chinese battery giant CATL, are already using the tech.

Why it’s hard: Without modules, it can be harder to control thermal runaway and maintain the battery pack’s structure. Plus, cell-to-pack makes replacing a faulty battery cell much harder, which means smaller flaws can require opening or even replacing the entire pack.

Silicon Anodes

Why it’s exciting: Lithium-ion batteries have graphite anodes. Adding silicon to the mix, though, could have huge upsides: more energy storage (meaning longer driving ranges) and faster charging, potentially down to a blazing six to 10 minutes to top up. Tesla already mixes a bit of silicon into its graphite anodes, and other automakers—Mercedes-Benz, General Motors—say they’re getting close to mass production.

Why it’s hard: Silicon alloyed with lithium expands and contracts as it goes through the charging and discharging cycle, which can cause mechanical stress and even fracturing. Over time, this can lead to more dramatic battery capacity losses. For now, you’re more likely to find silicon anodes in smaller batteries, like those in phones or even motorcycles.

It’s Kind of Happening

The battery tech in the more speculative bucket has undergone plenty of testing. But it’s still not quite at a place where most manufacturers are building production lines and putting it into cars.

Sodium-Ion Batteries

Why it’s exciting: Sodium—it’s everywhere! Compared to lithium, the element is cheaper and easier to find and process, which means tracking down the materials to build sodium-ion batteries could give automakers a supply chain break. The batteries also seem to perform better in extreme temperatures, and are more stable. Chinese battery-maker CATL says it will start mass production of the batteries next year and that the batteries could eventually cover 40 percent of the Chinese passenger-vehicle market.

Why it’s hard: Sodium ions are heavier than their lithium counterparts, so they generally store less energy per battery pack. That could make them a better fit for battery storage than for vehicles. It’s also early days for this tech, which means fewer suppliers and fewer time-tested manufacturing processes.

Solid State Batteries

Why it’s exciting: Automakers have been promising for years that groundbreaking solid state batteries are right around the corner. That would be great, if true. This tech subs the liquid or gel electrolytes in a conventional li-ion battery for a solid electrolyte. These electrolytes should come in different chemistries, but they all have some big advantages: more energy density, faster charging, more durability, fewer safety risks (no liquid electrolyte means no leaks). Toyota says it will finally launch its first vehicles with solid state batteries in 2027 or 2028. BloombergNEF projects that by 2035, solid state batteries will account for 10 percent of EV and storage production.

Why it’s hard: Some solid electrolytes have a hard time at low temperatures. The biggest issues, however, have to do with manufacturing. Putting together these new batteries requires new equipment. It’s really hard to build defect-free layers of electrolyte. And the industry hasn’t come to an agreement about which solid electrolyte to use, which makes it hard to create supply chains.

Maybe It’ll Happen

Good ideas don’t always make a ton of sense in the real world.

Wireless Charging

Why it’s exciting: Park your car, get out, and have it charge up while you wait—no plugs required. Wireless charging could be the peak of convenience, and some automakers insist it’s coming. Porsche, for example, is showing off a prototype, with plans to roll out the real thing next year.

Why it’s hard: The issue, says Jaswani, is that the tech underlying the chargers we have right now works perfectly well and is much cheaper to install. He expects that eventually, wireless charging will show up in some restricted use cases—maybe in buses, for example, that could charge up throughout their routes if they stop on top of a charging pad. But this tech may never go truly mainstream, he says.

Tesla Reveals New Details About Robotaxi Crashes—and the Humans Involved

Tesla Reveals New Details About Robotaxi Crashes—and the Humans Involved


For more than a year, Tesla has shielded details about its robotaxi crashes from public view. Now, the company has published new details in a federal database about 17 incidents, which took place between July 2025 and March 2026. In at least two of them, Tesla’s human employees appear to have played a hand in the crashes by remotely driving the otherwise autonomous cars into objects on the street.

In both crashes, which happened in Austin, “safety monitors” were in the vehicles’ passenger seats to oversee the still-fledgling self-driving tech, and no passengers were riding in the cars. Both crashes occurred at speeds below 10 miles per hour. The new details were first reported by TechCrunch.

In one incident, which took place in July 2025, the safety monitor experienced “minor” injuries after a remote worker drove the Tesla up a curb and into a metal fence at 8 mph. The monitor, who had requested help from Tesla’s remote driving team after the car stopped on the side of a street and wouldn’t move forward, was not hospitalized, Tesla reported.

The other incident, in January 2026, happened after a safety monitor requested navigation help from the remote team. The remote driver took control and drove the car straight into a temporary construction barricade at 9 mph. The crash left the robotaxi’s front left fender and tire scraped up, but Tesla didn’t report any injuries.

Tesla, which does not have a public relations team, did not respond to WIRED’s request for comment.

The new details draw attention to an often misunderstood but safety-critical part of autonomous vehicle operations: the human backstops who remotely monitor the robot cars and intervene when they get into trouble. All US self-driving operators maintain these remote teams, according to letters submitted to a US senator earlier this year. But Tesla appears to be an outlier because it more frequently allows these remote workers to directly drive the cars.

Other companies typically allow their workers to remotely provide input to the autonomous vehicle software, which the system can choose to use or reject. (Waymo says that specially trained workers can remotely drive its cars up to 2 mph, but said in February that it hadn’t used that functionality outside of training.)

Safety advocates have raised questions about remote driving, which can be challenging in places without consistent cellular connectivity and in contexts where remote drivers need a perfect understanding of a car’s surroundings to guide it out of complex situations.

The new details on the two Tesla crashes “raise questions about what the teleoperator can see in both coverage and resolution, and what kind of latency they are experiencing while driving,” Noah Goodall, an independent self-driving vehicle researcher, tells WIRED in a message.

Tesla’s still-fledgling robotaxi service is operating in three Texas cities: Austin, Dallas, and Houston. But the service has fewer than 100 vehicles operating in total, compared to Waymo’s nearly 4,000. Less than half of Tesla’s cars appear to operate without a safety monitor sitting in the passenger seat. Reuters reported this week that service wait times in Houston and Dallas, where robotaxis launched in April, are upward of 35 minutes. Even in Austin, where the cars have been carrying passengers for almost a year, a reporter for the publication found that robotaxis were sometimes completely unavailable.

Tesla CEO Elon Musk has said that autonomous vehicles and robotics are the automaker’s focus instead of manufacturing electric cars. Musk’s compensation—a potential $1 trillion paycheck by 2035—is now tied to vehicle and robot deliveries, as well as sales of not-yet-released self-driving subscriptions and the number of robotaxis in commercial operation.

Greg Brockman Officially Takes Control of OpenAI’s Products in Latest Shakeup


OpenAI told staff on Friday that it would reorganize the company as part of an ongoing effort to unify its product offerings, WIRED has learned. OpenAI cofounder and president Greg Brockman will now lead the company’s product strategy, in addition to his work on AI infrastructure, OpenAI confirms to WIRED. Brockman was previously assigned to oversee OpenAI products on an interim basis while CEO of AGI deployment, Fidji Simo, was on medical leave; the change is now official.

“We’re consolidating our product efforts to execute with maximum focus toward the agentic future, to win across both consumer and enterprise,” Brockman said in a memo to staff seen by WIRED. Brockman added that OpenAI’s products are naturally converging, and that the company has decided to merge ChatGPT and Codex into one unified experience.

OpenAI says it’s folding ChatGPT, its AI coding agent Codex, and its developer-facing API into one core product team. The company says that Codex is increasingly powering its consumer and enterprise offerings, which are gaining the ability to perform digital tasks autonomously on behalf of users.

Two other OpenAI leaders are also taking on larger roles at the company as part of the changes. OpenAI’s head of Codex, Thibault Sottiaux, has been tapped to lead the core product and platform across consumer, enterprise, and developer surfaces. Sottiaux was a key leader in building Codex into one of the company’s fastest-growing products of all time. OpenAI’s longtime head of ChatGPT, Nick Turley, is moving to a new role at the company that aims to revamp enterprise products. OpenAI says Turley will continue his work on ChatGPT, which he has helped grow to more than 900 million weekly active users since he took over in 2022.

The changes are the latest shakeup for OpenAI as leadership aims to refocus the company on a few key product areas, including ChatGPT, Codex, and its forthcoming “everything app.” Last month, OpenAI announced many executive changes, including that CEO of AGI dDeployment, Fidji Simo, was taking a medical leave to focus on her health. OpenAI previously said Brockman would oversee product strategy in her absence. The company tells WIRED that Simo remains on medical leave, and worked directly with Brockman on these organizational changes and product strategy.

In the last year, OpenAI has faced increasing pressure from competitors, including Anthropic in coding domains and Google in consumer chatbots. OpenAI leaders are hoping to simplify product offerings ahead of its plan to file for an IPO, which could happen later this year.

Other OpenAI executives left the company entirely last month, including the head of its AI workspace for scientists, Kevin Weil; head of Sora, Bill Peebles; and its chief technology officer of enterprise applications, Srinivas Narayanan.

This is a developing story. Please check back for updates.

Companies Keep Slashing Employees’ Benefits for the Worst Reasons

Companies Keep Slashing Employees’ Benefits for the Worst Reasons


Employee benefits are in the spotlight this week, and that’s because of three recent stories about US companies cutting back on non-wage compensations for workers.

A Texas tech consulting firm with a forgettable name—TTEC—suddenly became a lot more memorable when it suspended its discretionary 401(k) match program for 16,000 employees through at least the end of 2026. According to Business Insider, which viewed an internal TTEC memo, the company plans to invest in AI certifications, AI tools and training, and automation, among other things.

The auditing and consulting giant Deloitte is also reportedly slashing benefits for some workers starting next year. This includes reducing PTO, halving parental leave, and eliminating a $50,000 reimbursement for family planning services such as adoption, surrogacy, and IVF. San Francisco-based Zoom, meanwhile, has made a smaller-scale change and reduced its parental leave for employees from 22 weeks to 18 weeks for birthing parents.

So what’s the driving force behind this? And are there more cuts to come? The latter is impossible to answer, and the former is unfortunately more complicated than “corporate ghouls go AI.”

First off, “what Deloitte did is completely unconscionable,’” says Joan C. Williams, a professor at UC Law San Francisco, the author of several books on work culture and class dynamics, and an oft-cited scholar on these topics. The consulting firm is cutting the benefits of a specific class of internal workers—in admin, IT support, and finance—while leaving intact benefits for people in client-facing roles. An affected worker will see their parental leave cut from 16 weeks to just eight weeks.

“It treats people differently based on the type of job they’re in, and cutting any mother down to eight weeks of paid leave is just outlandish,” Williams says. “When labor is tight, employers are more generous. But once the power shifts, the benefits contract.”

AI certainly is a convenient excuse these days for any corporate decision that harms workers. But the impetus here is also the cost of the benefits themselves. Earlier this year subsidies from the Affordable Care Act lapsed, and people began dropping out of health care plans entirely. Insurers have cited this as one reason they’ve raised premiums.

Sarahjane Sacchetti, a former top executive at benefits administration companies Cleo and Collective Health, who is working on a new health care initiative, told me that the costs of employer-sponsored health plans have increased significantly over the past five years. A survey last year of over 1,700 US employers by the Mercer health care consulting group found that the health care cost per worker was expected to rise on average 6.5 percent in 2026, the highest since 2010. And this was after factoring in cost-reduction measures; otherwise, the cost of a plan would go up by nearly 9 percent.

“This just starts to eat into how you think about total compensation as an employer,” Sacchetti says. That doesn’t mean the corporation is the ‘good guy,’ she says, but the poor state of American health care policy and lack of safety net are responsible for a lot of the stress that plagues undercompensated or laid-off workers.

Williams points out that the US is one of the few countries that doesn’t offer a federal paid maternal leave—putting it in league with Papua New Guinea and Suriname. “This just shows how crazy it is to provide employee basics like pension and paid parental leave through private employers rather than how other industrialized countries do it,” Williams says. Her proposed solution? “The US needs to join the rest of the universe.”

The irony, of course, is that the US government professes to be obsessed with women having more babies. If women in the US are—as celebrity doctor Mehmet Oz put it this week in the Oval Office—“underbabied,” a comprehensive paid federal leave policy would be the obvious place to start. (Oz also said that “making babies” is “the most creative thing the universe knows.” Don’t tell the AI CEOs.)
