Asahi Kasei has entered into a licensing agreement with EAS Batteries, allowing the latter to utilize Asahi Kasei’s high-conductivity electrolyte technology in its upcoming ultra-high power (UHP) lithium-ion cells. This innovative advancement aims at enhancing performance and efficiency across various applications.
EAS Batteries is set to introduce its cylindrical UHP601300 LFP 22 cell by March 2026, featuring a lithium iron phosphate (LFP) cathode alongside the proprietary electrolyte technology. This partnership is expected to drive significant improvements in power density and cycle life.
The new electrolyte from Asahi Kasei promises superior ionic conductivity, reducing internal resistance and boosting performance at extreme temperatures. Specifically, the UHP601300 LFP 22 cell offers a continuous discharge specific power of 2,550 W/kg—a 60% increase over conventional cells—and achieves an impressive pulse discharge of 3,760 W/kg, marking a 10% enhancement.
Developed with support from the German Federal Ministry of Research under the “HEADLINE” project, this cell also boasts a cycle life of 2,400 cycles at room temperature before retaining 80% of its initial capacity. Its other notable features include a full charge and discharge cycle duration of just 22 minutes.
“The robustness of the electrolyte is critical for future high-power cell applications,” said Michael Deutmeyer, Managing Director of EAS Batteries. “With this collaboration, we are laying strong groundwork to scale our technology across multiple markets.”
