24M shares test data of new Impervio separator that helps reduce EV battery fires
Volkswagen-backed battery developer 24M Technologies has shared test data showcasing its Impervio separator technology, which helps reduce the risk of EV battery fires. The video footage below shows a side-by-side comparison of conventional EV cells overcharged with and without an Impervio separator in real-time, demonstrating the technology’s potential in the future.
24M Technologies is a US-based battery startup spun out of MIT that has redesigned the traditional battery cell using “SemiSolid” lithium-ion technology. Prospective benefits of these unique cells include 40% less production area, more efficient product recycling, and less CO2 during battery production.
In December 2021, we shared the news that Volkswagen Group had invested in the battery specialist as part of three separate partnerships to advance EV battery cell development and adjacent technologies.
With VW’s financial support, 24M announced a novel approach to EV battery recycling called “Liforever” this past March. This approach is implemented directly into the battery manufacturing process as a method to recycle all active battery materials like lithium iron phosphate (LFP) more efficiently and cost-effectively while bypassing the creation of black mass entirely.
In January 2024, 24M introduced a new approach to battery separators called “Impervio,” which addresses the growing concern of fire across EV battery cells, energy storage systems (ESS), and consumer applications when they are overcharged. You can learn more about how 24M’s Impervio separator helps reduce the risk of EV battery fires in the company’s explainer video here.
Most recently, 24M shared test data that visually demonstrates the potential of its Impervio separator, overcharging EV battery cells with and without the technology in real time. The results are encouraging.
24M data that shows its separator reduces EV battery fires
As a follow up to its initial announcement earlier this year, 24M Technologies has shared actual test data that exhibits how effective its Impervio technology can be at preventing EV battery fires.
24M explained that overcharging a battery cell, like those utilized in EVs, can lead to dendrite formation and an internal short, which can result in a fire or, even worse, an explosion. The Impervio separator obstructs dendrite propagation by controlling the cell at the individual electrode level, thus preventing dendrites from propagating and faulting. 24M also shared that its technology can prevent thermal runaway by monitoring a cell’s electrochemistry and implementing a failsafe in the event of a shorting out.
The company shared the following video of a side-by-side performance test of two separate 10 Ah NMC/graphite cells, one with an Impervio separator and one with a conventional separator, charged to 100%, then overcharged to 100% overcapacity or twice the specified maximum voltage.
As you can see in the video, the non-Impervio, off-the-shelf cells overheated via dendrite-caused micro shorts after 15 minutes, causing the battery to inevitably explode and catch fire after 38 minutes. The NMC cell with 24M’s Impervio technology, however, did not overheat or catch fire after an entire hour of overcharging. 24M Technologies president and CEO elaborated on the potential of the company’s Impervio separators:
Battery safety is a major roadblock to the widespread adoption of EVs. Recent EV fires around the globe have highlighted why new battery safety innovations are required. A sustainable energy future is only possible with innovations like Impervio, which can help prevent battery fires and create new opportunities for battery innovation
It will be interesting and exciting to see 24M’s Impervio technology implemented at a mass scale, as EV battery fires, although rare, are still a major concern for OEMs and consumers alike. It would also be nice to remove the talking point about EV fire risk from the conversation from naysayers and political pundits as an argument against EV adoption.

Robinhood stock hit an all-time high Friday as the financial services platform continued to rip higher this year, along with bitcoin and other crypto stocks.
Robinhood, up more than 160% in 2025, hit an intraday high above $101 before pulling back and closing slightly lower.
The reversal came after a Bloomberg report that JPMorgan plans to start charging fintechs for access to customer bank data, a move that could raise costs across the industry.
For fintech firms that rely on thin margins to offer free or low-cost services to customers, even slight disruptions to their cost structure can have major ripple effects. PayPal and Affirm both ended the day nearly 6% lower following the report.
Despite its stellar year, the online broker is facing several headwinds, with a regulatory probe in Florida, pushback over new staking fees and growing friction with one of the world’s most high-profile artificial intelligence companies.
Florida Attorney General James Uthmeier opened a formal investigation into Robinhood Crypto on Thursday, alleging the platform misled users by claiming to offer the lowest-cost crypto trading.
“Robinhood has long claimed to be the best bargain, but we believe those representations were deceptive,” Uthmeier said in a statement.
The probe centers on Robinhood’s use of payment for order flow — a common practice where market makers pay to execute trades — which the AG said can result in worse pricing for customers.
Robinhood Crypto General Counsel Lucas Moskowitz told CNBC its disclosures are “best-in-class” and that it delivers the lowest average cost.
“We disclose pricing information to customers during the lifecycle of a trade that clearly outlines the spread or the fees associated with the transaction, and the revenue Robinhood receives,” added Moskowitz.
Robinhood is also facing opposition to a new 25% cut of staking rewards for U.S. users, set to begin October 1. In Europe, the platform will take a smaller 15% cut.
Staking allows crypto holders to earn yield by locking up their tokens to help secure blockchain networks like ethereum, but platforms often take a percentage of those rewards as commission.
Robinhood’s 25% cut puts it in line with Coinbase, which charges between 25.25% and 35% depending on the token. The cut is notably higher than Gemini’s flat 15% fee.
It marks a shift for the company, which had previously steered clear of staking amid regulatory uncertainty.
Under President Joe Biden‘s administration, the Securities and Exchange Commission cracked down on U.S. platforms offering staking services, arguing they constituted unregistered securities.
With President Donald Trump in the White House, the agency has reversed course on several crypto enforcement actions, dropping cases against major players like Coinbase and Binance and signaling a more permissive stance.
Even as enforcement actions ease, Robinhood is under fresh scrutiny for its tokenized stock push, which is a growing part of its international strategy.
The company now offers blockchain-based assets in Europe that give users synthetic exposure to private firms like OpenAI and SpaceX through special purpose vehicles, or SPVs.
An SPV is a separate entity that acquires shares in a company. Users then buy tokens of the SPV and don’t have shareholder privileges or voting rights directly in the company.
OpenAI has publicly objected, warning the tokens do not represent real equity and were issued without its approval. In an interview with CNBC International, CEO Vlad Tenev acknowledged the tokens aren’t technically equity shares, but said that misses the broader point.
“What’s important is that retail customers have an opportunity to get exposure to this asset,” he said, pointing to the disruptive nature of AI and the historically limited access to pre-IPO companies.
“It is true that these are not technically equity,” Tenev added, noting that institutional investors often gain similar exposure through structured financial instruments.
The Bank of Lithuania — Robinhood’s lead regulator in the EU — told CNBC on Monday that it is “awaiting clarifications” following OpenAI’s statement.
“Only after receiving and evaluating this information will we be able to assess the legality and compliance of these specific instruments,” a spokesperson said, adding that information for investors must be “clear, fair, and non-misleading.”
Tenev responded that Robinhood is “happy to continue to answer questions from our regulators,” and said the company built its tokenized stock program to withstand scrutiny.
“Since this is a new thing, regulators are going to want to look at it,” he said. “And we expect to be scrutinized as a large, innovative player in this space.”
SEC Chair Paul Atkins recently called the model “an innovation” on CNBC’s Squawk Box, offering some validation as Robinhood leans further into its synthetic equity strategy — even as legal clarity remains in flux across jurisdictions.
Despite the regulatory noise, many investors remain focused on Robinhood’s upside, and particularly the political tailwinds.
The company is positioning itself as a key beneficiary of Trump’s newly signed megabill, which includes $1,000 government-seeded investment accounts for newborns. Robinhood said it’s already prototyping an app for the ‘Trump Accounts‘ initiative.

Korean auto giants Hyundai and Kia think lower-priced EVs will help minimize the blow from the new US auto tariffs. Hyundai is set to unveil a new entry-level electric car soon, which will be sold alongside the Kia EV2. Will it be the IONIQ 2?
Hyundai and Kia shift to lower-priced EVs
Hyundai and Kia already offer some of the most affordable and efficient electric vehicles on the market, with models like the IONIQ 5 and EV6.
In Europe, Korea, Japan, and other overseas markets, Hyundai sells the Inster EV (sold as the Casper Electric in Korea), an electric city car. The Inster EV starts at about $27,000 (€23,900), but Hyundai will soon offer another lower-priced EV, similar to the upcoming Kia EV2.
The Inster EV is seeing strong initial demand in Europe and Japan. According to a local report (via Newsis), demand for the Casper Electric is so high that buyers are waiting over a year for delivery.
Hyundai is doubling down with plans to introduce an even more affordable EV, rumored to be the IONIQ 2. Xavier Martinet, CEO of Hyundai Motor Europe, said during a recent interview that “The new electric vehicle will be unveiled in the next few months.”
The new EV is expected to be a compact SUV, which will likely resemble the upcoming Kia EV2. Kia will launch the EV2 in Europe and other global regions in 2026.
Hyundai is keeping most details under wraps, but the expected IONIQ 2 is likely to sit below the Kona Electric as a smaller city EV.
More affordable electric cars are on the way
Although nothing is confirmed, it’s expected to be priced at around €30,000 ($35,000), or slightly less than the Kia EV3.
The Kia EV3 starts at €35,990 in Europe and £33,005 in the UK, or about $42,000. Through the first half of the year, Kia’s compact electric SUV is the UK’s most popular EV.
Like the Hyundai IONIQ models and Kia’s other electric vehicles, the EV3 is based on the E-GMP platform. It’s available with two battery packs: 58.3 kWh or 81.48 kWh, providing a WLTP range of up to 430 km (270 miles) and 599 km (375 miles), respectively.
Hyundai is expected to reveal the new EV at the IAA Mobility show in Munich in September. Meanwhile, Kia is working on a smaller electric car to sit below the EV2 that could start at under €25,000 ($30,000).
According to the report, Hyundai and Kia are doubling down on lower-priced EVs to balance potential losses from the new US auto tariffs.
Despite opening its new EV manufacturing plant in Georgia to boost local production, Hyundai is still expected to expand sales in other regions. An industry insider explained, “Considering the risk of US tariffs, Hyundai’s move to target the European market with small electric vehicles is a natural strategy.”
Although Hyundai is expanding in other markets, it remains a leading EV brand in the US. The IONIQ 5 remains a top-selling EV with over 19,000 units sold through June.
After delivering the first IONIQ 9 models in May, Hyundai reported that over 1,000 models had been sold through the end of June, its three-row electric SUV.
While the $7,500 EV tax credit is still here, Hyundai is offering generous savings with leases for the 2025 IONIQ 5 starting as low as $179 per month. The three-row IONIQ 9 starts at just $419 per month. And Hyundai is even throwing in a free ChargePoint Home Flex Level 2 charger if you buy or lease either model.
Unfortunately, we likely won’t see the entry-level EV2 or IONIQ 2 in the US. However, Kia is set to launch its first electric sedan, the EV4, in early 2026.
