Description
Technical field
The present invention relates to new energy field, especially relate to a kind of aluminium-air cell catalyst cleaning method and its
Cleaning fluid.
Background technology
Metal-air battery is new generation of green battery, and its manufacturing cost is low, specific energy is high, the recyclable profit of raw material
With superior performance.Studying more metal-air battery at present has zinc-air battery, aluminium-air cell and lithium-air battery etc..
In galvanic series, aluminum ratio zinc is more active, can obtain higher cell voltage；One aluminium atom can discharge three electronics,
Aluminium can improve the energy of battery；In addition, it is aluminium rich reserves, cheap, therefore the progress of aluminium-air cell is very rapid, is
A kind of rising air cell.
Aluminium-air cell, is to be used as a kind of novel battery of battery material using aluminium and air.Aluminium as air cell sun
Pole material has the advantages that its is unique：Electrochemical equivalent is high, and the electrochemical equivalent of aluminium is 2980Ah/kg, for the highest in addition to lithium
Metal；Electrode potential is relatively born, and its standard electrode potential is -2.35V (vs.SHE) in alkaline solution, for anode material,
Current potential is more negative better, and battery can provide bigger electromotive force；The aboundresources of aluminium, it is cheap.At present, air cell aluminium sun
