EAS Batteries Launches High-Power LFP Cell with Asahi Kasei’s Acetolyte™ Electrolyte — Asahi Kasei Corporation

Event summary

EAS Batteries has commercialized its ultra-high-power LFP cell incorporating Asahi Kasei’s Acetolyte™ electrolyte, launched in March 2026.
The cell delivers 2,550 W/kg under continuous discharge, a 60% improvement over conventional electrolytes.
Asahi Kasei and EAS Batteries signed a licensing agreement in November 2025 for the electrolyte’s use in cylindrical LFP cells.
The companies aim to sublicense their combined technologies to global OEMs and battery manufacturers for mobility applications.
Prototypes of the 46xxx cell format, designed for low-voltage electric vehicle batteries, are already available for testing.

The big picture

Asahi Kasei’s strategy of licensing its Acetolyte™ electrolyte aligns with its medium-term management plan to monetize intangible assets. The collaboration with EAS Batteries underscores the growing trend of technology-sharing partnerships in the battery sector, aimed at accelerating innovation and reducing time-to-market for high-performance solutions. The focus on mobility applications highlights the increasing demand for advanced battery technologies in the automotive industry.
