Method of dismantling electricity storage device and apparatus of cutting electricity storage device

Abstract

A method of dismantling a battery includes a cutting step, a heating step, and a removing step. In one embodiment, the cutting step cuts a case of the battery with a band saw blade made of a material having a higher melting point than a material making up the case. The heating step heats the band saw blade to a temperature that is higher than the melting point of the material making up the case and is lower than the melting point of the material making up the band saw blade. The removing step removes cutting chips adhering to the band saw blade by applying an external force to the band saw blade that is heated in the heating step.
