The ideal choice for applications that demand maximum reliability and safety
High thermal stability
The sodium-ion technology used by HEIWIT is designed for stationary energy storage applications, where safety and thermal stability are key parameters.
Recyclability
Wide operating range
The HEIWIT systems are designed to operate over a wide temperature range, including under particularly severe conditions, in accordance with the product specifications.
Lithium-free and cobalt-free
The sodium-ion chemistry used in HEIWIT systems does not use lithium or cobalt, relying instead on more abundant raw materials.Â
Long cycle life
Sodium-ion technology is particularly suited to stationary energy storage, where lifespan, safety and thermal behaviour matter more than weight and volume.
