Alcoa and Phinergy enter joint development agreement for high energy-density aluminum-air batteries

Green Car Congress

However, parasitic hydrogen evolution caused by anode corrosion during the discharge process is a well-known obstacle to commercialization of such a system, because it not only causes additional consumption of the anode material but also increases the ohmic loss in the cell. kWh/kg of Al—second only to the Li-air battery (13.0
