【Haichuan Teahouse】Aluminum-air battery
Thread Content
The principle of aluminum-air batteries is very simple. Pure aluminum is used as the cathode, oxygen in the air as the anode, and an aqueous solution of sodium hydroxide or potassium hydroxide as the electrolyte. Aluminum is oxidized to alumina, and chemical energy is converted into electrical energy. During recycling, alumina can be electrolyzed to recover aluminum once again.
Electrolytic aluminum is a major consumer of energy and a significant source of pollution; this doesn’t make much sense
“\"Alumina needs to be recycled through electrolysis to obtain aluminum again\" – does that mean it cannot be recharged and aluminum has to be replaced?
