Abstract
A method for manufacturing a secondary battery in which the preparation of at least one of a positive electrode and ta negative electrode includes forming an electrode material layer on a metal sheet material to serve as an electrode current collector, thereby providing an electrode precursor, and cutting out electrodes from the electrode precursor to form a plurality of electrodes. Each of the electrodes has a non-rectangular shape.
