Information
Wattium develops high-power, NaFeC (non-lithium) stationary batteries engineered for grid stability and power-dominant services. Its proprietary bipolar architecture enables 12C performance, ultra-fast cycling, and 30,000+ cycle life.
Unlike conventional multi-hour storage lithium batteries, Wattium supports critical grid functions such as synthetic inertia, fast frequency response, and grid-forming operation—helping utilities and large energy users build more stable, resilient power systems.
