The new battery uses a modified the aluminium-air battery structure by placing ceramic and carbonaceous materials between aqueous electrolyte and electrodes as an internal layer.
The 0.7-0.8 V aluminum-air battery, which provides 400-800 mA/cell, claims to have a theoretical specific energy level of 8,100 Wh/kg. Theoretical specific energy of a commercialized lithium-ion battery is 120-200 Wh/kg which means that the aluminium-air battery possesses theoretical capacity more than 40 times as large as that of a lithium-ion battery.
The new battery claims to overcome a major barrier to commercialization which has been the high corrosion rate of aluminium during the electrochemical process. Fuji Pigment Co. Ltd. is planning to commercialize the aluminium-air battery by spring 2015.
