POUCH CASE FOR SECONDARY BATTERY AND SECONDARY BATTERY USING THE SAME

摘要

A pouch case for a secondary battery in which the width of a metal layer in a plurality of layers to constitute the pouch case is formed narrower than those of other layers so that the metal layer is not exposed to an outer surface of the pouch case. A secondary battery includes an electrode assembly provided with one or more electrode tabs. A pouch case has the electrode assembly accommodated therein, and is formed of a plurality of layers. In the secondary battery, any one of the plurality of layers to constitute the pouch case is formed as a metal layer of which width is narrower than those of the other layers.
