24M Technologies, founded in 2010 and headquartered in Cambridge, Massachusetts, is transforming the way batteries are designed and manufactured. The company’s innovations focus on improving energy storage solutions for a wide range of applications, including electric vehicles (EVs), energy storage systems (ESS), aerospace, and more. By advancing battery technologies and production techniques, 24M strives to provide safer, cost-effective, and environmentally sustainable energy solutions. The companies SemiSolidTM manufacturing process is a novel approach to battery design, enabling greater efficiency and reduced production complexity compared to conventional methods. 24M is committed to delivering innovative energy solutions that address critical industry needs and support the transition to a more sustainable energy future.
Battery Technology
The cornerstone of 24M’s innovations lies in its proprietary SemiSolid™ platform, which eliminates traditional electrode binders and adds simplicity to the battery manufacturing process. This approach significantly lowers production costs, reduces material waste, and enhances battery safety and overall performance. By using fewer components and steps in production, manufacturers can achieve higher energy densities without compromising reliability.
Additionally, the company has introduced complementary technologies to further improve advanced battery performance. The Impervio™ separator addresses safety challenges in lithium-ion and lithium-metal batteries by preventing dendrite formation and reducing the risk of thermal runaway. This is an important development for industries seeking safer and more durable batteries. The Eternalyte™ electrolyte is another innovation, specifically designed to enhance the life cycle and rate capabilities of lithium-metal batteries, making them more practical for EVs, ESS, and other demanding applications.
Another notable innovation is 24M’s Electrode-to-Pack (ETOP) technology, which integrates electrodes directly into the battery pack. This streamlines production and increases energy density, providing manufacturers with a more efficient method to deliver higher performing energy storage solutions. The company’s technologies also promote recyclability, ensuring that lithium-ion and lithium-metal batteries can contribute to the broader goals of reducing environmental impact.
Recent Projects
In September 2024, 24M expanded its global operations by unveiling a new Research & Development and manufacturing facility in Rayong, Thailand. This 71,000 square-foot facility supports the production of up to 100 MWh of SemiSolid™ battery cells and is aimed at supplying key markets, including electric mobility. Initial pilot production at the facility has already begun, with some of its first validation samples being shipped to a prominent mobility OEM based in India.
Additionally, 24M has seen success through its partnership with Kyocera Corporation. In response to growing demand, Kyocera announced plans to increase production capacity for SemiSolid™ residential energy storage batteries in Japan by FY2026. These developments illustrate the growing adoption of 24M’s technologies in commercial applications.
Investors
24M has attracted significant investment from a broad range of funders, demonstrating trust in its potential. In its Series H funding round, the company raised over $51 million, led by Nuovo+, one of its key strategic partners. Other notable participants in this round included Kyocera Corporation, Mitsubishi Chemical, Dai Nippon Printing, and Lucas TVS.
Previous investors have included high-profile organizations such as the Volkswagen Group, Fujifilm, and North Bridge Venture Partners, with funding amounts totaling over $166 million in earlier rounds. This backing has allowed 24M to develop and commercialize its cutting-edge battery technologies while supporting global scalability.
