It is a device which uses the oxygen in the air as the cathode active
substance, the zinc as the anode active substance, the alkaline solution as
electrolyte, so as to convert the chemical energy into electrical energy.
3.2
Mechanical switching zinc air battery
It refers to the zinc air battery which realizes energy supplementation
through mechanically replacing the zinc electrode and electrolyte.
3.3
Cell
It refers to a basic unit device which directly converts the chemical energy
into electrical energy. It is composed of electrode, diaphragm, electrolyte,
