Fast Company

24M, an MIT startup, has been named to Fast Company’s list of the most innovative companies in the energy space for 2025, reports Alex Pasternack. The company “has been developing a portfolio of battery technologies designed to make batteries that are safer, cheaper, cleaner, and longer-lasting,” explains Pasternack. “Its technologies include a semisolid electrode for conventional and novel battery chemistries, which gives the battery more energy density and requires fewer materials, and a unique separator that monitors the cell and helps prevent the aberrations that cause shorts and fires.”
