24M Technologies has introduced its 24M ETOP™ (Electrode-to-Pack) platform to streamline U.S. battery production for electric vehicles, eVTOL aircraft, energy storage systems and consumer electronics. Launched in October 2023, ETOP is an electrode- and chemistry-agnostic manufacturing approach that integrates sealed anode/cathode pairs directly into a battery pack, eliminating conventional cell and module assembly steps. By reducing inactive materials such as metals and plastics, this technique boosts active electrode content in the pack to as much as 80% by volume, compared with 30–60% in traditional designs.
“The pressure to compete on price, design and performance is mounting for American industries that are heavily reliant on imported batteries,” said Naoki Ota, 24M President and CEO. “The U.S. must advance battery innovation, not just scale production to close the gap with competitors overseas. Our 24M ETOP offers U.S. manufacturers the technology they need to leapfrog Asian counterparts with industry-leading energy density, first-of-its-kind design flexibility, and lower manufacturing costs.”
ETOP uses a single machine to form, stack, wire and seal electrodes within the pack, enabling compact, high-voltage configurations with fewer manufacturing stages. Companies can adopt the system on standard assembly lines with relatively low capital outlays and minimal facility modifications. The streamlined process also makes battery makers eligible for Section 45X production tax credits under the U.S. Inflation Reduction Act, supporting gigawatt-hour scale output in domestic facilities.
Because ETOP is chemistry-agnostic and can accommodate a wide range of voltages and form factors, it suits applications from grid-scale storage to light mobility products including e-bikes, two- and three-wheelers. The platform is particularly well-matched to burgeoning eVTOL markets, where lightweight, high-energy-density packs are critical for extended range and payload capacity.
For enhanced safety and low-temperature performance, ETOP can be paired with 24M’s Impervio™ separator and Eternalyte™ electrolyte, which supports fast charging down to –40 °C. Together, these components enable battery packs capable of achieving up to 1,000 miles of range without the weight and complexity penalties of solid-state designs.
Naoki Ota, president and CEO of 24M, noted that American manufacturers face growing pressure on price, performance and design flexibility—and that ETOP offers a pathway to outpace overseas competitors through higher energy density and simplified production.
Headquartered in Cambridge, Massachusetts, 24M Technologies is committed to reinventing battery architectures and manufacturing methods to reduce costs, improve safety, enhance recyclability and strengthen domestic supply chains.
