1. the processing method of a lithium battery, it is the processing method that possesses the lithium battery of anodal member, described anodal member has positive electrode collector and the positive electrode active material layer that is made of aluminium, described positive electrode active material layer comprises the positive active material that is made of the composite oxides that contain lithium and transition metal and is fixed on the described positive electrode collector, and this processing method has:

  • The acid solution treatment process, this operation makes any the acid solution in phosphate aqueous solution, carbonated water and the hydrogen sulfide water contact with the described positive electrode active material layer that constitutes described anodal member and the surface of described positive electrode collector, peels off described positive electrode active material layer from described positive electrode collector;

    WithOxalic acid treatment operation, this operation make oxalic acid aqueous solution contact with substance to be processed, and described substance to be processed contains the metal ingredient that derives from described positive electrode active material layer.
