SECONDARY BATTERY AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2018/154989

A1

The present invention provides technology for more suitably positioning an external terminal of a secondary battery having a non-rectangular shape. This method is for producing a secondary battery that comprises a wound electrode body configured from a positive electrode and a negative electrode and that has a non-rectangular shape in a planar view. A positive electrode precursor and a negative electrode precursor are layered on each other via a separator to form an electrode precursor layered body and the electrode precursor layered body is wound to form the wound electrode body. In particular, the electrode precursor layered body has a comb tooth shape in a planar view, and the wound electrode body is formed to have a non-rectangular shape by winding so that the winding axis of winding is approximately parallel to the direction of extension of a terminal element of the secondary battery.
