Concern and research.
However, the cycle life of zinc-air battery is still relatively low at present, the commercial applications of zinc-air battery are limited.Limit
The key factor of zinc-air battery cycle life processed is a lack of the Bifunctionan air electrode of long-life, i.e., has catalysis oxygen analysis simultaneously
Go out the electrode of reaction and oxygen reduction reaction.
For double functional air battery in charging process, the high potential of anode is strong to generations such as oxygen reduction catalyst, carbon carriers
Strong corrosiveness seriously reduces the cycle life of air electrode, and researcher has developed three electrode zinc-air batterys thus,
It is made of other necessary attachmentes such as zinc load, oxygen precipitation anode, hydrogen reduction anode, electrolyte, in charging, zinc load and oxygen
Anode composition battery is precipitated, in electric discharge, zinc load forms battery with hydrogen reduction anode.In three electrode zinc-air batterys, fill
Electric process oxygen reduction electrode does not access circuit, therefore avoids the high potential etching problem of oxygen reduction electrode.But three electrode zinc are empty
Pneumoelectric pond increases the complexity of system, especially for three electrode zinc-air battery groups, generally requires manual switching battery company
It connects mode or using complicated automatic control system, increases the cost of zinc-air battery group, limit it and be widely applied.
