High-power batteries with extended lifetime

Our features: High rate capability, cost efficiency, customized shape

Lithium-based high-rate batteries are widely used in compact and portable devices where downtimes or unplanned maintenance does not translate into financial risks. However, in a growing number of industrial markets, battery storage needs to be built on safe and reliable technologies to offer durability and meet power requirement whatever the weather conditions and over the equipment lifetime.

Ultra-high-performance batteries developed in our Lab, which can be produced with discharge rate up to 60C, can be considered as the game changer in terms of safety, reliability, and performance. Our batteries are built on different cell chemistries (classic, specialized) and find their application in multiple industries.
