Phinergy

Phinergy is an Israeli company developing aluminum-air battery technology, positioned as an energy storage and EV range-extension solution. The company is based in Israel and has attracted attention for its work on metal-air electrochemical cells, particularly aluminum-air batteries that use oxygen from the air as a cathode reactant, enabling very high theoretical energy density. Detailed public information on founding year, headcount, funding rounds, and current executive leadership is limited.

Phinergy's primary focus is aluminum-air battery systems, which generate electricity through the electrochemical reaction between aluminum anodes and atmospheric oxygen. The technology targets electric vehicles as a range-extender alongside conventional lithium-ion packs, as well as stationary energy storage applications. The aluminum-air chemistry offers a very high energy-to-weight ratio compared to conventional batteries, though the aluminum anode is consumed during discharge and must be replaced or recycled rather than recharged conventionally. Alcoa has been publicly named as a strategic partner, with the collaboration focused on the aluminum supply and recycling side of the system.
