24M Technologies has unveiled its new 24M ETOP™ (Electrode-to-Pack) battery architecture, which can increase electric vehicle range by up to 50% through improved energy density and design flexibility.
Unlike conventional lithium-ion packs, which rely on modules built from individual cells filled with inactive materials, 24M ETOP integrates sealed electrodes directly into the pack using thin polymer films. This eliminates the need for traditional cell casings and modules, dramatically improving packaging efficiency.
This means that 80% of the pack’s volume can be active, energy-storing electrodes – compared to just 30–60% in standard designs. This breakthrough allows manufacturers to either extend EV range using the same chemistry or reduce costs by switching to more affordable alternatives like LFP, without sacrificing performance.
For example, a 75kWh NMC battery could be scaled to over 100kWh in the same footprint, boosting range by 33%. Alternatively, OEMs could swap NMC for LFP and maintain range while cutting costs.
24M ETOP also supports customisable pack shapes and voltages, from compact 48V units to high-voltage 800V systems. Its modular design simplifies manufacturing, improves safety tolerances, and reduces capital investment by eliminating the need for high-precision equipment.
Naoki Ota, president and CEO of 24M Technologies, said, “Minimising packaging materials and wasted space, 24M ETOP brings a step change in performance.
“It truly is the closest version of an ideal battery – it is essentially all active material in a sophisticated wrapper.”
ETOP is compatible with 24M’s Impervio separator, Eternalyte electrolyte, and LiForever electrode, further enhancing safety, longevity and performance.
