About

Metal Light builds zinc-air batteries for long-duration grid storage, storing energy as shelf-stable zinc metal for utilities, industrial operators and data centers.

The design separates power hardware from stored energy. Zinc reacts with air to release electricity on demand, and on-site electricity turns zinc oxide back into zinc metal. Because zinc does not self-discharge, it can be shipped, stockpiled or held indefinitely. Metal Light says its batteries are built in America from domestic materials.
