ABSTRACT:
The method of recovering useful materials from spent secondary batteries for electric vehicles comprises a step of separating spent secondary batteries for electric vehicles into a cover portion and a housing portion, a step of taking out electrode plates to separate them from the housing portion, a step of disassembling electrode plates into positive electrode plates and negative electrode plates, and a step of cutting the pole section so that the positive electrode plates can be separated from the negative electrode plates.
