24M Technologies has announced a new battery manufacturing platform that could reshape how electric vehicle (EV) batteries are made. The system, called 24M ETOP (Electrode-to-Pack), eliminates the need for traditional battery cells by integrating electrodes directly into the battery pack.
The Massachusetts-based company said the innovation could enable 1,000-mile-per-charge EV battery packs while reducing costs and improving safety. “Our 24M ETOP offers U.S. manufacturers the technology they need to leapfrog Asian counterparts with industry-leading energy density,” said Naoki Ota, president and chief executive officer of 24M Technologies.
Traditional battery designs use multiple layers of cells and modules, much of which contributes little to actual energy storage. The ETOP platform removes these intermediate components, instead using sealed anode and cathode pairs that connect directly within the pack. According to the company, this approach allows up to 80% of the pack’s volume to store energy, compared with 30% to 60% in conventional designs — potentially increasing EV range by as much as 50%.
The company said its design provides a “cost-effective path to build compact, high-voltage batteries with maximum energy density.”
Beyond electric vehicles, 24M Technologies said the ETOP system could also support next-generation applications such as electric vertical take-off and landing (eVTOL) aircraft, where lightweight, high-power batteries are essential for performance and safety.
