This secondary battery electrode is provided with a core material configured from a metal foil that softens at less than or equal to 200° C., and an electrode mixture sheet which is bonded on the surface of the core material. The electrode mixture sheet includes an active material and a fibrous binder, and the active material bites into the core material, with the maximum bite depth at least 30% of the thickness of the core material. The fibrous binder may for example have polytetrafluoroethylene as the main component.

Electrode for secondary battery and method for producing the same

A method for producing a lithium-containing composite oxide, the method including: a first step of preparing a lithium hydroxide; a second step of heating a hydroxide containing nickel and a metal M1 other than lithium and nickel to 300° C. or higher and 800° C. or lower, to obtain a composite oxide containing the nickel and the metal M; a third step of mixing the lithium hydroxide and the composite oxide, to obtain a mixture; a fourth step of compression-molding the mixture, to obtain a molded body; and a fifth step of baking the molded body at 600° C. or higher and 850° C. or lower, to obtain a baked body.
