Abstract
A method of producing an electrode includes the steps of filling an active material in an electrode substrate made of woven or non-woven fabric having its fiber surface coated with metal, and pressing the electrode substrate to obtain an electrode, wherein the pressing is performed using the electrode substrate having a thickness of less than 2.0 t when the thickness of the electrode after the pressing is t. This ensues that the electrode substrate has a thickness allowing the active material of a sufficient amount to be filled therein, and a battery electrode in which the filled active material is unlikely to peel off from the electrode substrate can be produced. Accordingly, a battery electrode having a desired thickness and desired capacity and that can suppress degradation in battery performance due to repeated charge and discharge, and its producing method are provided.
