24M Technologies to unveil electrode-to-pack technology at 2023 Japan Mobility Show

24M has announced it will introduce a transformative new battery technology — the 24M Electrode-to-Pack system — at the Japan Mobility Show October 26 – November 5. 24M ETOP™ is a streamlined battery pack system that features electrodes packaged directly into the battery pack, removing the need for individual cells and modules.

Prior to 24M ETOPTM, cell manufacturers, automotive OEMs and ESS integrators have built battery packs and modules from individual cells. However, current lithium-ion battery cells have a large fraction of inactive, non-charge-carrying materials — supporting metals and plastics — within a cell’s casing. These inactive materials reduce module and energy density and add unnecessary expense and waste. Enabled by the 24M Unit Cell design, the 24M ETOP™ technology eliminates unnecessary cell materials within the battery pack and allows manufacturers to achieve the highest energy density available at the pack level while cutting costs.

“24M ETOP™ will be a game-changer for electric mobility and energy storage systems because it delivers unmatched energy density,” said Naoki Ota, 24M President and CEO. “This innovative new battery technology is enabled by our Unit Cell technology and is reflective of what’s yet to come from 24M. We are moving beyond our core technology — the 24M SemiSolid™ manufacturing platform — into a company with a revolutionary technology set that will deliver truly transformative solutions for a better energy future.”

A Transformed Pack for Breakthrough Energy Density

24M will be demonstrating 24M ETOP™ in the AZAPA booth: Booth E6001, East 6 Exhibition Hall. In addition to enabling the highest available energy density at the pack level, the 24M ETOP™ system delivers dramatic improvements in other key areas.

  • Performance: Achieve electrode (not cell) packing efficiencies of over 70%, the highest pack-level volume utilization efficiency available.
  • Cost: In addition to its streamlined process and decreased materials usage, it enables unit electrodes to be connected in a combination of series and parallel — an industry first. By eliminating additional connection components, it also further reduces the overall pack cost.
  • Range and Cycle Life: Higher packing efficiencies and energy density provide benefits for both EV and ESS applications, boosting range and capacity.
  • Safety: The 24M SemiSolid™ Electrode and Unit Cell technology continues to provide unmatched safety when subjected to mechanical abuse.
  • Pack Design Flexibility: The 24M Unit Cell can be connected in series, parallel and a combination of series and parallel directly within a pack, enabling configurations that are no longer bound or limited by individual cell voltage (V) and capacity (Ah).
