COVER MATERIAL FOR BATTERY AND METHOD FOR MANUFACTURING SAME

摘要

The present invention provides a pouch-type cover material for a battery, comprising: an outermost layer; a barrier layer comprising aluminum or aluminum alloy plating; and an innermost layer, wherein an oxidized coating layer is formed on at least one surface of the barrier layer so that the battery has a surface resistance of at least 0.1 ㏀/㎠. The cover material effectively maintains a moisture-repellent property while effectively and significantly increasing durability to corrosion and electricity insulation.
