24M’s core technology is its proprietary SemiSolid™ platform which eliminates traditional electrode binders and simplifies battery manufacturing. This reduces production costs, material waste, and improves battery safety and performance. Complementary technologies include the Impervio™ separator to prevent dendrite formation and reduce thermal runaway risk in lithium-ion and lithium-metal batteries, and Eternalyte™ electrolyte to improve lifecycle and rate capabilities of lithium-metal batteries. Their Electrode-to-Pack (ETOP) technology integrates electrodes directly into battery packs to streamline production and increase energy density, promoting recyclability and reducing environmental impact.
24M produces SemiSolid™ battery cells and residential energy storage batteries incorporating their SemiSolid™ platform, Impervio™ separator, Eternalyte™ electrolyte, and Electrode-to-Pack (ETOP) technology, designed for electric vehicles, energy storage systems, and other demanding applications.
In 2024, 24M launched a new R&D and manufacturing facility in Rayong, Thailand, with capacity for 100 MWh of SemiSolid™ battery cells, supplying markets including electric mobility. They began pilot production and shipped validation samples to a prominent mobility OEM in India. 24M partnered with Kyocera Corporation, which plans to increase production capacity for SemiSolid™ residential energy storage batteries in Japan by FY2026, indicating growing commercial adoption of 24M technology.
24M raised over $51M in Series H funding led by Nuovo+ with participation from Kyocera Corporation, Mitsubishi Chemical, Dai Nippon Printing, and Lucas TVS. Earlier funding rounds totaled over $166M from investors including Volkswagen Group, Fujifilm, and North Bridge Venture Partners, supporting the development and commercialization of their battery technologies.
