<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing an electrode preventing drop of battery characteristics such as OCV failure caused because an active material extended from a current collector comes off and becomes foreign materials after electrode rolling in the manufacture of a lithium secondary battery. <P>SOLUTION: The foreign materials are removed without leaving at an electrode plate end part by applying a brush 2 to the electrode plate end part in the horizontal direction and sucking immediately after rolling. The brush 2 is positioned on the inside of a suction port 1, suction is conducted at a flow velocity of 4-20 m<SP>3</SP>/min, thereby removing removed active materials without being dropped. <P>COPYRIGHT: (C)2009,JPO&INPIT |
