24M Technologies was founded with one purpose: To change the way the world makes batteries. Led by some of the industry’s foremost inventors, scientists and entrepreneurs, 24M has combined decades of battery expertise with radical, out-of-the-box thinking to develop a revolutionary approach to battery technology.

Critical roadblocks sit in the way of a world powered by affordable, high-performance batteries, from cost challenges to safety concerns and sustainability issues. At 24M, we’re tackling these issues at their core, reimagining and re-engineering the battery from the ground up.

Our commitment to building a sustainable future has fueled us since our origins in the labs of MIT and our launch in 2010. Today, with a rapidly expanding suite of battery technologies, we’re enabling the global transition to a cleaner, electrified world.

Our mission: Powering a greener future.​

24M’s mission is clear: A better battery for a better energy future. To build it, we work with leading industry players worldwide, including energy storage system integrators, EV battery manufacturers and OEMs. By addressing the challenges still holding back these organizations today, we can create safer, longer-lasting and more affordable solutions that meet the world’s growing energy demands. We believe batteries play an essential role in a green and thriving future for our planet — so we’re pushing them forward to shape the world we envision.

24M Technologies unveils 1,000 miles EV battery – Telematics Wire

24M Technologies unveils 1,000 miles EV battery​

US company unveils EV battery tech that could reach 1,000 miles on single charge — here's how it could transform the auto industry

According to Fast Company, a new electric vehicle battery developed by a Massachusetts-based company has the potential to deliver 1,000 miles of range between charges. After separating from MIT in 2015, 24M Technologies integrated a number of pre-existing technologies to produce a battery that has a significantly greater range than anything else available on the US market.

In place of lithium-ion, 24M’s batteries employ more energy-dense lithium metal. It appears that a unique separator that aids in fire prevention has helped to lessen those safety concerns.

Additionally, the semisolid electrolyte used in the batteries eliminates the need for materials like plastic, copper, and aluminum. EVs with 1,000-mile ranges won’t be available in the US for at least a few years because automakers haven’t tested the batteries. But that isn’t the case in China, where a plug-in hybrid is reportedly available for 1,300 miles on a single charge (and for a fraction of the price of EVs in the States).

Despite being less of a problem than many people think, “range anxiety,” or the fear of being left in an electric car without access to a charging station, still influences people’s decisions to purchase or not purchase an electric vehicle.

24M and Its Impervio Battery Separator Technology Honored by Fast Company with 2025 World Changing Ideas Award​

CAMBRIDGE, Mass., June 11, 2025--(BUSINESS WIRE)--24M Technologies, Inc. announced today that Fast Company has recognized its Impervio™ battery separator technology as a 2025 World Changing Idea. This annual recognition honors bold and transformative efforts that tackle the world’s most pressing issues — from fresh sustainability initiatives and cutting-edge energy developments to ambitious pursuits of social equity that help enrich the world.

"The World Changing Ideas Awards have always been about showcasing the art of the possible," says Fast Company editor-in-chief Brendan Vaughan. "We’re proud to recognize the organizations and leaders that are making meaningful progress on the biggest issues of our time." This award follows Fast Company’s recent recognition of 24M as a 2025 Most Innovative Company.


24M’s Impervio separator is a breakthrough in battery fire safety, designed to address key risks like overcharging and internal shorts, the main causes of thermal runaway that leads to fires and costly recalls. By actively suppressing dendrites and enabling early fault detection, Impervio can prevent thermal incidents before they start. It enables next-generation lithium-ion and lithium-metal batteries to deliver enhanced performance and safety without sacrificing manufacturability across EVs, energy storage systems, consumer electronics, aviation, ebikes and more.

"As batteries become central to everything from electric vehicles to grid storage and personal devices, fire safety can no longer be an afterthought," said Naoki Ota, President and CEO of 24M. "We’re proud to be recognized by Fast Company for our work to make batteries fundamentally safer. With Impervio, we’ve developed a game-changing technology that proactively helps prevent catastrophic failures for safer, more reliable clean energy. It’s innovations and ideas like these that move us closer to a truly sustainable and secure energy future."

This year’s World Changing Ideas awards showcase 50 winners across 12 categories and 50 additional winners across industries, for a total of 100 outstanding projects. A panel of Fast Company editors and reporters selected the winners from a pool of more than 1,500 entries and judged applications based on their impact, sustainability, design, creativity, scalability, and ability to improve society.

US battery startup 24M Technologies shuts down despite $1B+ valuation​

US battery startup EnerVenue opens first factory in China's Changzhou

CHANGZHOU, China, Sept 22 (Reuters) - A US battery startup that scrapped plans to make Kentucky the site of its first factory has instead built it in China, exposing ‌the limits of President Donald Trump's efforts to lure manufacturing home just as he welcomes Chinese President Xi Jinping for a summit.

EnerVenue starts mass production at its manufacturing facility in the eastern Chinese city of Changzhou on Thursday, the same day Trump meets Xi in Washington, as relations between the superpowers remain strained by a tariff war the US president launched partly to bring back manufacturing and jobs.

Chief Executive Henning Rath told Reuters the date was a coincidence, and the decision to manufacture in China instead of the US was down to skills and supply chain depth — particularly in Changzhou, which bills itself as China’s “new energy capital.”

“The secret sauce ⁠is this industrial cluster,” Rath said, citing the density of hydraulics, pneumatics and automation specialists, along with engineers able to iterate quickly on what he called a "first-of-its-kind" line.

Without building in China, Rath said, it would be "very difficult with the capital available" to prove the manufacturing process at a commercial scale.
