Classification and Characteristics of Air Batteries in Electric Encyclopedia

Zinc air battery

Zinc air battery, which uses activated carbon to absorb oxygen or pure oxygen in air as positive active material, zinc as negative electrode, ammonium chloride or caustic alkali solution as electrolyte, is a primary battery. Also known as zinc-oxygen battery.

Lithium air batteries

Large capacity lithium air batteries is not a new concept, has not yet universal reason is that it has fatal flaw.

At present, Lithium ion batteries is the next generation of plug-in hybrids and electric vehicles ideal, but the potential is limited. Theoretical energy density is greater than that of lithium ion battery metal lithium air batteries. It with new structure greatly enhance the energy density of batteries. Due to use the oxygen in the air on the anode as active substances, in theory, the capacity of the anode density is infinite, can increase the capacity. In addition, if the cathode using lithium metal, theoretical capacity will be higher than that of lithium ion rechargeable batteries single digits.

But lithium air batteries are not yet popular because it has fatal flaw, namely solid reaction products lithium oxide can be in the positive accumulation, to make contact with the air of electrolyte is blocked, leading to discharge to stop.
