Phinergy’s zinc-air technology provides renewable energy storage solutions at a cost up to five times lower than current lithium-ion-based technologies.

Zinc-air battery technology has been around for a while, most notably as a primary battery for lightweight hearing aids. However, large-scale rechargeable zinc-air did not reach maturity stage.

Phinergy has developed a rechargeable zinc-air technology decoupling charging, discharging and storage units, enabling to increase storage capacity (up to hundreds of hours) at minimal cost.
