Method of producing an electrode plate used for a lithium secondary battery and a lithium secondary battery
First Claim
1. A method of producing an electrode plate for use in a lithium secondary battery comprising applying a coating slurry on a collector to form a coating thereon, said coating slurry including an active material mixture agent and oxalic acid added thereto, and pressing the coating, wherein the amount of oxalic acid in the coating slurry is 0.05-10 wt. % based on the active material mixture agent.

Abstract
A method of producing an electrode plate used for a lithium secondary battery and a lithium secondary battery containing such an electrode plate. The electrode plate is produced by coating a coating slurry of an active material mixture agent added with oxalic acid on a collector, drying and pressing, so as to obtain an electrode plate improved in charge-discharge cycle characteristics when used in a lithium secondary battery.
