Secondary-battery electrode and secondary-battery electrode manufacturing method, and secondary battery and method of manufacturing secondary battery

Abstract

An object is to provide a secondary-battery electrode that is capable of suppressing a short circuit between adjacent positive and negative electrodes when the secondary-battery electrode is applied to an electrode body of a secondary battery. A secondary-battery electrode (10) includes a thin-plate-shaped metal core body (11) and an active material layer (12a, 12b) containing an active material and formed on two surfaces of the core body (11). In a cut end portion (15) of the electrode, an end portion (16) of the core body (11) is positioned inward of an end portion (17a, 17b) of the active material layer (12a, 12b) in a surface direction Y of the electrode.
