Title:
SECONDARY CELL PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/131344
Kind Code:
A1
Abstract:
The present invention provides a secondary cell production method having even higher production efficiency. In the production method of the present invention, the production of a positive electrode and/or a negative electrode involves obtaining an electrode precursor by forming an electrode material layer on a metal sheet material serving as an electrode current collector, and forming a plurality of electrodes by cutting out the electrodes from the electrode precursor. The shapes of the cutouts of the plurality of electrodes include paired shapes comprising small piece shapes which are relatively small and large piece shapes which are relatively large.
