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.

Save Up to 40% With These Acer Promo Codes and Discounts
Acer is one of the top largest PC manufacturers in the world, perhaps best known for its gaming line and budget-friendly options. If you’ve already got your eye on an Acer product like a laptop or monitor, and are shopping at the company’s online storefront, you should be using one of these Acer promo codes and coupons to save some cash on your purchase.
Save 40% on Accessories When You Build an Acer Bundle
If you’re buying from Acer, you’re most likely shopping for either a desktop PC or laptop. With this discount, you can get a really solid deal on accessories if you bundle it with a mouse, laptop bag, or headset. When you go to purchase a PC, just click “Build Bundle” and you’ll see some of the eligible options, all of which are reduced by 40%. The Nitro Mechanical Keyboard, for example, goes from $50 to just $30. That 40% is a real discount, too, as that same keyboard costs $50 on Amazon when I checked.
Beyond peripheral add-ons, you can also save 10% off Acer Care Plus extended service plans or McAfee LiveSafe antivirus subscriptions. You can bundle up to five products together to save the most money. If you’re headed off to college (or have a kid in the family), a bundle like this can get you everything you need for a gaming or studying setup on the go.
Shop Rotating Weekly Deals on Monitors and Gaming Gear
Acer’s PC gaming offerings come in either the flagship Predator brand or the budget-tier Nitro. Acer offers rotating weekly deals on everything from monitors to gaming laptops, some of which are my favorites that I’ve tested in their given category. The Acer Nitro V 16, for example, was a budget gaming laptop that I recommended quite a lot last year because of its incredible price. The one I tested was the entry-level version with an Nvidia RTX 5050 inside, but Acer has the RTX 5060 model in its own storefront. It’s $100 off right now at $1,200, which comes with 16 GB of RAM and a terabyte of storage. In fact, it’s only $30 more than the RTX 5050 model, despite offering a significant jump in gaming performance. These discounts are reflected right on the product pages, so there’s no promo code, discount code, or coupon code required.
Acer has a wide selection of monitors available, too, whether that’s a massive 49-incher or a more modest 27-inch gaming workhorse. One of my favorite discounts I saw right now was the Acer Nitro XV2, a 27-inch 1440p display with a 300 Hz refresh rate. It’s 44% off at the time of writing, bringing the price down to just $250. Because these discounts are swapped out on a weekly basis, it’s worth checking back to see if the product you’re eyeing has a new discount.
Select Customers Can Get 15% Off Their Purchase
Acer also offers a number of added discounts at checkout, including 15% off for students. Students will need to verify through Student Beans or SheerID. Because a lot of the devices Acer offers are budget-friendly, they can be attractive for students, and the extra 15% off is the icing on the cake.
We tested the Acer Swift 16 AI last year and really enjoyed the high-resolution, OLED screen and impressively quiet performance. Acer has the smaller version of this same laptop available, the Swift 14 AI, which is currently $150 off. You also might check out the Acer Chromebook Plus 514, a laptop we liked quite a bit when we reviewed it in 2024.
Acer offers this same 15% discount for active duty military, veterans, and their families. It also applies to healthcare professionals, which can be verified through its healthcare discount portal.

AI Research Is Getting Harder to Separate From Geopolitics
The world’s top AI research conference, the Conference on Neural Information Processing Systems—better known as NeurIPS—became the latest organization this week to become embroiled in a growing clash between geopolitics and global scientific collaboration. The conference’s organizers announced and then quickly reversed controversial new restrictions for international participants after Chinese AI researchers threatened to boycott the event.
“This is a potential watershed moment,” says Paul Triolo, a partner at the advisory firm DGA-Albright Stonebridge who studies US-China relations. Triolo argues that attracting Chinese researchers to NeurIPS is beneficial to US interests, but some American officials have pushed for American and Chinese scientists to decouple their work—especially in AI, which has become a particularly sensitive topic in Washington.
The incident could deepen political tensions around AI research, as well as dissuade Chinese scientists from working at US universities and tech companies in the future. “At some level now it is going to be hard to keep basic AI research out of the [political] picture,” Triolo says.
In its annual handbook for paper submissions, issued in mid-March, NeurIPS organizers announced updated restrictions for participation. The rules stated that the event could not provide services including “peer review, editing, and publishing” to any organizations subject to US sanctions, and linked to a database of sanctioned entities. It included companies and organizations on the Bureau of Industry and Security’s entity list and those on another list with alleged ties to the Chinese military.
The new rules would have affected researchers at Chinese companies like Tencent and Huawei who regularly present work at NeurIPS. The database also includes entities from other countries such as Russia and Iran. The US places limits on doing business with these organizations, but there are no rules around academic publishing or conference participation.
The NeurIPS handbook has since been updated to specify that the restrictions apply only to Specially Designated Nationals and Blocked Persons, a list used primarily for terrorist groups and criminal organizations.
“In preparing the NeurIPS 2026 handbook, we included a link to a US government sanctions tool that covers a significantly broader set of restrictions than those NeurIPS is actually required to follow,” the event’s organizers said in a statement issued Friday. “This error was due to miscommunication between the NeurIPS Foundation and our legal team.”
Before they reversed course, the conference organizers initially said that the new rule was “about legal requirements that apply to the NeurIPS Foundation, which is responsible for complying with sanctions,” adding that it was seeking legal consultation on the issue.
Immediate Backlash
The new rule drew swift backlash from AI researchers around the world, particularly in China, which produces a large quantity of cutting-edge machine learning papers and is home to a growing share of the world’s top AI talent. Several academic groups there issued statements condemning the measure and, more importantly, discouraging Chinese academics from attending NeurIPS in the future. Some urged Chinese academics to contribute instead to domestic research conferences, potentially helping increase the country’s influence in relevant science and tech fields.
The China Association of Science and Technology (CAST), an influential government-affiliated organization for scientists and engineers, said Thursday that it would stop providing funding for Chinese scholars traveling to attend NeurIPS and would use the money instead to support domestic and international conferences that “respect the rights of Chinese scholars.”
CAST also said it will no longer count publications at the 2026 NeurIPS conference as academic achievements when evaluating future research funding. It’s unclear if the organization will reverse course now that NeurIPS has walked back the new rule.

Iranian Hackers Breached Kash Patel’s Email—but Not the FBI’s
Handala’s second claim, however—that it hacked the FBI—seems, for now, to be fiction. All evidence points to Handala having breached Patel’s older, personal Gmail account. Widely believed to be a “hacktivist” front for Iran’s intelligence agency the MOIS, Handala suggested on its website that the emails contained classified information, but the messages initially reviewed by WIRED didn’t appear to be related to any government work. TechCrunch did find, however, that Patel appears to have forwarded some emails from his Justice Department email account to his Gmail account in 2014.
Handala, which cybersecurity experts have described to WIRED as an “opportunistic” hacker group whose cyberattacks and breaches are often calculated more for their propaganda value than their tactical impacts, has nonetheless made the most of Patel’s embarrassing breach. “To the whole world, we declare: the FBI is just a name, and behind this name, there is no real security,” the group wrote in its statement. “If your director can be compromised this easily, what do you expect from your lower-level employees?”
Handala Hackers Put $50 Million Bounty on Trump and Netanyahu’s Heads
For further evidence of Handala’s bombastic rhetoric, look no further than another post on its website earlier this week (we’re intentionally not linking to it) that offered a $50 million bounty to anyone who could “eliminate” US president Donald Trump and Israeli prime minister Benjamin Netanyahu. “This substantial prize will be awarded, directly and securely, to any individual or group bold enough to show true action against tyranny,” the hackers’ statement read, along with an invitation to any would-be assassins to reach out via the encrypted messaging app Session. “All our communication and payment channels utilize the latest encryption and anonymization technologies, your safety and confidentiality are fully guaranteed.”
That bounty, Handala explained, was posted in answer to a statement about Handala published on the US Department of Justice website last week that offered $10 million for information leading to the identity or location of anyone who carries out “malicious cyber activities against US critical infrastructure” on behalf of a foreign government.
“Our message is clear: If you truly have the will and the power, come and find us!” Handala wrote in its response. “We fear no challenge and are prepared to respond to every attack with even greater force.”
In yet another post on its website this week, Handala also claimed to have doxed 28 engineers at military contractor Lockheed Martin working in Israel and threatened them with personal harm if they didn’t leave the country within 48 hours. When WIRED tried calling the phone numbers included in Handala’s leaked data, however, most of them didn’t work.
Apple says no device with its Lockdown Mode security feature enabled has ever been successfully compromised by mercenary spyware in the nearly four years since its launch. Amnesty International’s security lab head, Donncha Ó Cearbhaill, also says his team has seen no evidence of a successful attack against a Lockdown Mode–enabled iPhone. And Citizen Lab, which has documented several successful spyware attacks against iPhones, says none involve a Lockdown Mode bypass, while in two cases its researchers found the feature actively blocked attacks against NSO Group’s Pegasus and Intellexa’s Predator. Google researchers, meanwhile, found one spyware strain that simply abandons infection attempts when it detects the feature is enabled.
Lockdown Mode works by disabling commonly exploited iPhone features, such as most message attachment types and features like links and link previews. Incoming FaceTime calls are blocked unless the user has previously called that person within the past 30 days. When the iPhone is locked, it blocks connections with computers and accessories. The device will not automatically join nonsecure Wi-Fi networks, and 2G and 3G support is disabled. Apple has also doubled bounties for researchers who detect any Lockdown Mode bypass, with payouts up to $2 million.
