Asahi Kasei said it has signed a licensing agreement with Germany’s EAS Batteries for its acetonitrile-based electrolyte technology, aimed at supporting the development and market launch of a new ultra-high-power lithium-ion cell for demanding mobility and industrial uses.
The Japanese chemical company said on Wednesday that the electrolyte, first demonstrated in June 2024, enables higher power output at low temperatures and improved durability at high temperatures. The new cylindrical cell, which uses a lithium iron phosphate (LFP) cathode, is expected to be launched by March 2026.

According to Asahi Kasei, the cell delivers a specific power of 2,550 W/kg during continuous discharge—about 60% higher than conventional electrolyte-based cells—and up to 3,760 W/kg in a two-second pulse discharge. Testing also showed a cycle life of 2,400 cycles at 5C/5C at room temperature, with a full charge and discharge in just 24 minutes. Lower internal resistance also reduces heat generation and improves overall efficiency.
Developed under Germany’s “HEADLINE” project, funded by the Federal Ministry of Research, Technology and Space, the 22-Ah UHP601300 LFP 22 cell was designed to meet performance requirements in marine, railway, and construction machinery sectors.

Both companies said they plan to sublicense their combined technologies to global OEMs and battery manufacturers to accelerate industrial adoption. Asahi Kasei aims to sign at least ten new licence agreements by fiscal 2027, targeting cumulative profits of around ¥10 billion (about 600,000 euros) by 2030.
“Our collaboration with Asahi Kasei sets a strong foundation for advancing cell quality and performance, especially for high-power cells,” said Michael Deutmeyer, Managing Director of EAS Batteries. “The robustness of the electrolyte is key—not only for EAS products but also for scaling our technology across markets.”
Osamu Matsuzaki, Senior Executive Officer of Asahi Kasei and Head of Corporate R&D and IP, added: “We are proud to provide high ionic conductivity electrolyte technology that contributes to battery cells which set a new benchmark for high power output. By combining our technology with the expertise of EAS, we achieved an advanced cell design with unprecedented performance.”
