Abstract

Disclosed herein is a battery cell configured to have a structure in which an electrode assembly is mounted in a battery case formed of a laminate sheet including a resin layer and a metal layer in a state in which the electrode assembly are connected to electrode terminals protruding outward from the battery case. The electrode assembly is configured such that separators are respectively disposed between cathodes and anodes, each of which is formed by applying a compound including an electrode active material to a current collector. At least a portion of an inside of the battery case corresponding to an outer circumference of the electrode assembly has an upward sloping structure in which a width of the battery case increases upward in vertical section or a downward sloping structure in which the width of the battery case increases downward in vertical section.
