"Aluminium–air batteries ( Al–Air) batteries produce electricity from the reaction of oxygen in the air with aluminium. They have one of the highest energy densities of all batteries.Aluminum is used as ANODE (-) and air rather oxygen in the air is used as CATHODE (+).(I am still not sure what will be the role of the graphene in GrapenEra’s battery. My research is going on about this issue.)The AL-Air battery has a theoretical specific energy level of 8,100 Wh/kg and has the second largest capacity among various types of potential secondary batteries. Theoretical specific energy of a commercialized Lithium-ion battery is 120-200 Wh/kg.Therefore, the aluminium-air battery possesses theoretical capacity more than 40 times as large as that of a lithium-ion battery."
