Zusammenfassung: | To provide an electrode that can be easily mass-produced.SOLUTION: A method for manufacturing an electrode of the present invention is a method for manufacturing an electrode in which a plurality of electrode body parts are connected in a belt shape with electrode connection parts therebetween and electrode terminal are formed on the electrode body parts on one side, the electrode with a laminated structure having an active material layer and a separator layer in which the electrode body parts and electrode connection parts are formed on a collector layer and on both sides thereof, and includes: applying the active material layer on both faces of a collector sheet, including approximately the entirety of an outer peripheral contour of the electrode within an application range of the active material, including a leading end of the electrode terminal in an unapplied part of the active material, forming a punching part for extending an extension part to an outer peripheral part of an electrode body on the other end side, forming a belt-like structure consisting of an electrode terminal corresponding part, an electrode body part corresponding part, and the extension part inside the punching part while supporting both ends with the electrode terminal corresponding part and the extension part, forming a coating for separator layer formation on a base end side of the electrode terminal corresponding part and both front and back faces of an electrode structure corresponding part and the extension part, and cutting at the leading end side of the electrode terminal corresponding part and the extension part.SELECTED DRAWING: Figure 7
【課題】本発明は、大量生産が容易な電極の提供を目的とする。【解決手段】本発明の電極の製造方法は、複数の電極本体部が電極接続部を介し帯状に接続され、一端側の電極本体部に電極端子が形成された電極であり、電極本体部と電極接続部が集電体層とその両面に形成された活物質層及びセパレータ層を有する積層構造とされた電極の製造方法であり、集電体シートの表裏両面に活物質層を塗布し、活物質層の塗布範囲に電極の外周輪郭のほぼ全体を含め、活物質層の未塗布部に電極端子の先端部を含め、他端側の電極本体の外周部に延出部を延出させる打ち抜き部を形成し、その内側に電極端子相当部と電極本体部相当部と延出部からなる帯状構造体を電極端子相当部と延出部とで両端支持状態で形成し、電極端子相当部の基端側と電極構造体相当部と延出部の表裏両面にセパレータ層形成用塗膜を形成し、電極端子相当部の先端側と延出部で切断する。【選択図】図7 |
