Electrode recycling methods and battery manufacturing methods

Abstract

This invention relates to a method for recycling electrodes and a method for manufacturing batteries. The embodiments pertain to a method for recycling electrodes and a method for manufacturing batteries. A method for recycling electrodes capable of improving the recovery rate of active materials is provided, as well as a method for manufacturing batteries utilizing this electrode recycling method. According to the embodiments, a method for recycling electrodes is provided, comprising: heat-treating a first electrode, the first electrode comprising a first current collector and an active material layer supported on the first current collector and containing active material, an adhesive, and a conductor, at a temperature below the melting point of a first current collector, thereby obtaining a heat-treated product satisfying the following formula: A×B>C, where A is the tensile strength of the first current collector [N / mm²], B is the thickness of the first current collector [mm], and C is the 180° peel strength of the heat-treated product [N / mm]. A step of separating a mixture comprising active material and a conductor from the heat-treated product; and a step of using at least the active material of the mixture to manufacture an electrode.
