German battery manufacturer EAS Batteries has moved its ultra-high-power lithium-ion LFP cell from launch to commercial reality, marking a rapid scale-up just months after its initial introduction in March 2026.

 

At the heart of the breakthrough is a licensing partnership with Japan’s Asahi Kasei and its Acetolyte electrolyte—a novel acetonitrile-containing formulation designed to push ionic conductivity higher, slash internal resistance, and unlock stronger performance across extreme temperature conditions.

 

The collaboration was formalized in November 2025, when Asahi Kasei signed a licensing agreement allowing EAS Batteries to integrate the electrolyte into its cylindrical LFP cells. The result is the newly commercialized UHP601300 LFP 22 cell—positioned as a flagship product in Asahi Kasei’s broader push to monetize its materials IP through licensing.

 

With a nominal capacity of 22 Ah, the cell delivers 2,550 W/kg under continuous discharge—about 60% higher than comparable cells using conventional electrolytes. In a 2-second pulse discharge, it reaches 3,760 W/kg, while also showing strong endurance with 2,400 cycles at 5C/5C and 100% depth of discharge, retaining 80% capacity at room temperature.

 

For comparison, conventional electrolyte cells achieve 1,550 W/kg under continuous discharge and 3,420 W/kg in pulse conditions, highlighting the performance gap opened by the Acetolyte system.

 

Samples of the new cells are already being evaluated by customers across multiple industries, signaling early commercial traction beyond the lab.

 

EAS Batteries and Asahi Kasei are now extending their collaboration further, agreeing to sublicense the combined technologies to global OEMs and battery manufacturers with a clear eye on mobility applications. 

 

Work is also underway on the next-generation 46xxx cell format, aimed at low-voltage electric vehicle systems, with prototypes already in customer testing and a launch targeted for 2026.

 

“The successful commercialisation of our new cell featuring Asahi Kasei’s Acetolyte marks another important milestone in our strategic partnership. 

 

"Our collaboration on the new 46xxx cell format is also progressing smoothly, underscoring the strength of our joint development approach and our ability to accelerate innovation from concept to market readiness," said EAS' Managing Director Michael Deutmeyer.

 

Osamu Matsuzaki, Senior Executive Officer of Asahi Kasei and Head of Corporate R&D and IP, emphasized the speed of execution behind the breakthrough.

 

“The short time from signing our license agreement in November 2025 to the start of serial production in March 2026 reflects the focused and highly collaborative efforts between EAS Batteries and Asahi Kasei. 

 

"Together, we have translated advanced electrolyte technology into a commercially viable high-power cell within just a few months. Building on this momentum, we are already working on the next cell format and look forward to further advancing high-performance battery solutions.”

 

Beyond the product itself, Asahi Kasei is positioning Acetolyte within a broader strategy tied to its medium-term management plan announced in April 2025. The company is actively pursuing “Technology-value Business Creation,” aiming to monetize patents, know-how, data, and algorithms through licensing-driven, asset-light commercialization.

 

The goal is ambitious: at least 10 new licensing agreements between fiscal 2025 and 2027, and a cumulative profit contribution of ¥10 billion or more by around 2030—signaling a clear pivot toward scaling innovation through intellectual property rather than manufacturing alone.
