EAS Batteries launches ultra‑high‑power 22 Ah LFP cell using Asahi Kasei Acetolyte
- EAS Batteries commercialised a 22 Ah LFP cylindrical cell in March 2026 using Asahi Kasei's acetonitrile-containing electrolyte Acetolyte.
- Asahi Kasei licensed Acetolyte to EAS in November 2025 and the partners will sublicense technologies to OEMs while evaluating a 46xxx cell format with prototypes and a 2026 target launch.
- Cell performance: 2,550 W/kg continuous (40C, 880 A) and 3,760 W/kg 2s pulse (60C, 1,320 A) versus 1,550 W/kg continuous for conventional electrolyte, and ~2,400 cycles at 5C/5C, 100% DoD to 80% capacity.
- Asahi Kasei's medium-term plan targets at least 10 new license agreements in fiscal 2025–2027 and a cumulative profit contribution of ¥10 billion or more by around 2030.
Product
EAS Batteries commercialized the UHP601300 22 Ah cylindrical LFP cell in March 2026; the cell uses Asahi Kasei’s acetonitrile-containing electrolyte, Acetolyte.
Performance
Nominal capacity 22 Ah; continuous discharge 2,550 W/kg (880 A, 40°C) versus 1,550 W/kg (550 A, 25°C) for a conventional electrolyte; 2 s pulse 3,760 W/kg (1,320 A, 60°C) versus 3,420 W/kg (1,320 A, 60°C); cycle life ~2,400 cycles at 5C/5C, 100% DoD to 80% at room temperature; samples are in customer evaluation.
Commercial and technical roadmap
Asahi Kasei licensed Acetolyte to EAS in November 2025; the partners plan to sublicense the combined technologies to OEMs and battery manufacturers and are evaluating a 46xxx cell format with prototypes available and a targeted 2026 launch for low‑voltage EV applications.
Electrolyte and strategy
Acetolyte is reported to have high ionic conductivity that lowers internal resistance and improves rate capability across temperatures, which the companies say can reduce pack size and cost while increasing energy density; Asahi Kasei’s medium‑term plan (April 2025) aims for at least 10 new license agreements in fiscal 2025–2027 and a cumulative profit contribution of ¥10 billion by around 2030.
