24M Technologies Launches ETOP Battery System to Boost EV Range by 50%

24M Technologies’ new Packaging System to Accelerate EV Range

24M Technologies, a leading battery technology company, has introduced a new packaging system that promises to elevate the EV range by 50% through improved energy density. The 24M ETOP (Electrode-to-pack) system replaces traditional battery cells by adding sealed electrodes into the battery packs. The technology can be integrated with other 24M products, which include the company’s electrolyte and impervious separator systems.

Technology’s Potency

The technology identifies a major inefficiency imbalance in recent lithium-ion batteries, where a significant proportion of the area is occupied by inactive materials, such as plastics and metals within the cell casings. Traditional battery packs consist of electrodes that occupy 30% to 60% of their volume, with the remainder comprising structural components. The 24M ETOP locks anode and cathode together in thin polymer films, discarding the requirement for single modules and cells. This idea enables electrodes to proceed with 80% of a pack’s volume, as stated by the company.

The system has the potential to work with multiple battery chemistries, including LFP, NCA, NMC, and sodium-ion, among others. Furthermore, the company provided an example of how the technology could be applied in practice. A practice of utilizing a 75kWh NMC battery, specifically designed for mid-sized EVs, can be leveraged to achieve above 100kWh with the same pack size and chemistry, marking a 33% increase in range. Alternatively, manufacturers can opt for an affordable LFP chemistry while maintaining the same range as traditional NMC packs.

Apart from improving energy density, the 24M ETOP provides a flexible design that allows battery packs to take various forms with different voltages and shapes. The locked electrodes are arrangeable in parallel and series configurations, suitable for voltages ranging from 48V up to 400-800V systems. Manufacturing advantages include lower equipment investment costs and easier, safer tolerances for single electrodes. The company claims that the system eliminates the need for accurate manufacturing equipment typically used in traditional battery production.

President and CEO at 24M technologies, Naoki Ota, said,

“The 24M ETOP brings a positive difference in the performance, by replacing the traditional cell-to-module-to pack construction with electrode-to-pack construction, accelerating energy density. The 24M ETOP makes it easy to build safe, small, and flexible high-voltage batteries, introducing a future opportunity for electric vehicle manufacturers. By providing longer ranges with the same chemistry or range with reduced cost, trustworthy chemistries at the same place.”
