24M Technologies has introduced the 24M electrode-to-pack (ETOP) system, designed to enhance energy density and potentially extend the driving range of electric vehicles by up to 50%. This innovative battery packing system integrates sealed, energy-storing electrodes directly into the battery pack, eliminating the traditional cells and modules that often occupy space and materials inefficiently.
The ETOP system replaces inactive components in traditional lithium-ion packs with sealed electrode pairs, maximizing the volume of active materials within the pack regardless of the chemistry used, such as nickel manganese cobalt (NMC), lithium iron phosphate (LFP), nickel cobalt aluminum (NCA), sodium ion, lithium titanate oxide (LTO) or lithium sulfur (LiS). This design allows electrodes to comprise up to 80% of the pack's volume, a significant improvement over the 30-60% typical in conventional designs.
This advancement offers manufacturers the flexibility to either enhance the EV's range by increasing the energy density within the same-sized pack or reduce costs by opting for more affordable chemistries without compromising range. For instance, a 75-kWh NMC battery can be upgraded to over 100 kWh in the same footprint, offering a one-third increase in range. Alternatively, manufacturers can substitute NMC with lower-cost LFP, maintaining similar performance levels.
The ETOP system also allows for unmatched design freedom, enabling packs to be constructed in virtually any shape, enhancing both performance and cost-effectiveness. Safety and production yield are improved as the sealed electrodes permit looser tolerances and require less precision equipment, reducing the capital investment needed. Moreover, the architecture supports simple series and parallel connections, facilitating configurations ranging from compact 48-V units to larger 400-800-V packs, with formation possible in series to lower equipment costs — a significant capital concern in battery manufacturing.
Additionally, ETOP aligns with 24M's other proprietary technologies, such as the Impervio separator, Eternalyte electrolyte and LiForever electrode, all aimed at producing safer, longer-lasting and higher-performing batteries. Collectively, these innovations represent a comprehensive reimagining of battery technology, promising a future of more affordable EVs with greater range, safety and design flexibility.
