Document Type and Number:
WIPO Patent Application WO/2018/084162
Kind Code:
A1
Abstract:
[Problem] The invention is to provide: a power storage element electrode capable of suppressing an electrical contact between an electrode and a tab section of another electrode caused by unexpected layer shifting, or the like; a power storage element equipped with the power storage element electrode; and a production method for the power storage element electrode. [Solution] One aspect of the present invention is the power storage element electrode comprising: a conductive electrode base material having a main body section and one or a plurality of tabular tab sections; and an insulation layer covering the main surface and the side surfaces of a base-end portion of each of the tab sections. Another aspect of the present invention is the power storage element equipped with the power storage element electrode. Another aspect of the present invention is the production method for the power storage element electrode comprising a step of forming, in the conductive electrode base material having the main body section and the one or a plurality of tabular tab sections, the insulation layer covering the main surface and the side surfaces of the base-end portion of each of the tab sections.
