Abstract
According to the condition of aluminum laminated film corrosion behavior happened in the pouch Li-ion battery,the forecast method of corrosion behavior about aluminum laminated film was studied.The method of chemical etching which used HF to etch the aluminum laminated film to case corrosion,then sprayed penetrating agent onto the polypropylene layer,could be directly used to judge whether the polypropylene layer was damaged.The method of using the meter to measure the insulation resistance which was calculated according to the resistance between the electrode and the aluminum laminated film,could be used to detect the broken polypropylene layer of the finical product.The insulation resistance of finical product with broken polypropylene layer was lower than the calculated value.The corrosion behavior of aluminum laminated film in pouch Li-ion battery could be effectively predicted by using chemical etching and insulation resistance testing method.关键词
