A cathode film of ultra-low temperature lithium battery, its making method and application

The present invention belongs to the field of electrochemical techniques, in particular to a method for preparing the composite anode membrane cryogenic lithium ion battery anode composite film obtained by this process as well as legal by chemical plating. A lithium ion battery anode composite film produced by the method of the present invention and the PC-based electrolyte having a good compatibility, effectively avoid decomposition and release of the PC graphite structure, the charge and discharge capacity and cycle performance of PC based electrolytes They are relatively good, as the anode film may cryogenic lithium ion battery. Further, the method of the present invention may be workable, reproducible, low cost and stable quality of the resulting product.
