Abstract
A manufacturing method of a secondary battery is provided to improve a manufacturing efficiency of a non-rectangular electrode. The manufacturing method is provided for a secondary battery and includes forming the non-rectangular electrode. The step of forming the electrode includes, prior to forming an electrode precursor by applying an electrode material layer raw material to a metal sheet material that becomes a current collector, controlling a wettability of a local portion of a surface of the metal sheet material to the electrode material layer raw material and forming a wettability control region in the local portion. The local portion becomes a cutaway region of the non-rectangular electrode.
