American company promises 1,000-mile EV range with new battery tech

24M Technologies has announced its 24M ETOP (Electrode-to-Pack) technology, a revolutionary manufacturing platform that the company claims will enable a cost-effective and safe 1000-mile-per-charge battery pack.

This new platform integrates electrodes directly into the battery pack, eliminating the cells. This is an improvement on the cell-to-body (CTB) technology which eliminated modules, integrating cells directly into the battery pack. By doing so, 24M ETOP promises a cost-effective path to build compact, high-voltage batteries with maximum energy density.

Current battery platforms use cells and modules, which means a significant portion of battery packs only serve only for structure or safety, and are not actively involved in energy storage. 24M ETOP eliminates this waste through the use of sealed anode and cathode pairs that are integrated directly into the pack. The company says this increases volume of the energy-storing material to 80% of a pack's volume, compared to 30–60% in conventional designs. This means up to 50% more range for EVs.

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. — Naoki Ota, president and CEO of 24M.

Beyond EVs, the technology holds great potential for emerging markets such as eVTOL (electric vertical take-off and landing) aircraft, where compact, lightweight designs delivering maximum power and extended range are critical.
