- EAS Batteries launches a 22 Ah LFP cell with significantly higher power output using Acetolyte electrolyte.
- Asahi Kasei and EAS Batteries are preparing a 46xxx-format battery cell for mobility applications in 2026.
Germany-based EAS Batteries has announced the commercialization of its new ultra-high-power lithium-ion LFP battery cell, marking a significant advancement in battery performance for future mobility applications. The development integrates the Acetolyte electrolyte technology from Asahi Kasei, which contains acetonitrile and is designed to provide higher ionic conductivity. This enhanced conductivity helps lower internal resistance within the cell while improving charge and discharge rate capability, enabling substantially higher power delivery without altering the core battery chemistry.
The newly commercialized 22 Ah High-Power LFP Cell demonstrates notable performance improvements compared with conventional lithium-ion cells that use standard electrolytes. During continuous discharge operation, the battery achieves a specific power output of 2,550 W/kg, representing approximately a 60% improvement over comparable cells using traditional electrolyte formulations. The enhanced power capability makes the technology suitable for applications requiring rapid energy delivery while maintaining stable battery performance characteristics.
Under demanding pulse discharge conditions, the battery continues to demonstrate strong performance. During a two-second pulse discharge test, the cell reaches a specific power output of 3,760 W/kg, which is approximately 10% higher than cells equipped with conventional electrolytes. These results highlight the role of electrolyte optimization in improving battery power density and supporting applications where short-duration high-power output is essential.
Performance Specifications of the 22 Ah LFP Cell
The battery also delivers strong durability alongside its power advantages. According to the companies, the cell can achieve a cycle life of 2,400 cycles at 100% depth of discharge while retaining 80% of its original capacity. This combination of high-power performance and extended operational life is important for mobility and industrial applications where long-term reliability and frequent charge-discharge cycles are critical requirements.

Technology Licensing and Future Mobility Expansion
EAS Batteries and Asahi Kasei intend to license their combined battery and electrolyte technologies to global OEMs and battery manufacturers. Through this strategy, the companies aim to accelerate adoption across mobility sectors and enable broader deployment of high-power lithium-ion solutions. Licensing is expected to support manufacturers seeking improved battery performance without extensive redesign of existing battery architectures.
Development of 46xxx Battery Cell Platform
Beyond the newly commercialized cell, both companies are advancing development of a 46xxx-format battery cell that will also utilize the Acetolyte electrolyte technology. The new format is scheduled for launch in 2026, with prototype cells already available for testing and validation activities. Initial target applications focus primarily on low-voltage electric vehicle battery systems, where enhanced power delivery and long cycle life can provide meaningful performance benefits for future vehicle platforms.
