ABSTRACT:
An external case for secondary batteries, and a secondary battery using the external case, in which the covering surfaces for the lower surface and side surfaces of a pouch type core pack are joined to prevent unfolding due to the resilience of the material. The external case includes: a base covering the lower surface of the pouch type cell, a pair of sidewalls joined to two opposing longer edges of the base to respectively form single linear boundaries, and covering two broad side surfaces of the pouch type cell, and skirts extending from two longer edges of each of the sidewalls, and covering two narrow side surfaces of the pouch type cell. The base, sidewalls, and skirts are all formed of a metallic material.
