Description
Technical field
The present invention relates to the technical field of metal-air cell, particularly a kind of aluminium alloy air battery cathode structure.
Background technology
In known metal-air chemical cell, aluminum-air cell principle and the present invention are the most close.Aluminum-air cell utilizes aluminium as the anode of battery, and catalytic oxygen does negative electrode, strong alkali solution as electrolyte solution, when there is chemical reaction respectively at the two poles of the earth in aluminium and oxygen, battery discharge.The chemical reaction that example that to take electrolyte as NaOH (the very close electrolyte solution of chemical property of potassium and sodium also available hydrogen potassium oxide solution replaces NaOH potassium solution) solution be now occurs in battery has:
Anode: 4Al-12e=4Al3
+
Negative electrode: 3O
2+ 6H
2o+12e=12OH
-
Net reaction: 4Al+3O
2+ 6H
2o+4NaOH=4NaAl (OH) 4+E (electricity) ↑+H (heat) ↑
4NaAl(OH)4＝4NaOH+4Al(OH)3
Anode surface can occur from rotten reaction simultaneously:
2Al+6H
