Abstract
A secondary battery is disclosed. In one aspect, the secondary battery includes an electrode assembly and a case comprising an accommodation region configured to accommodate the electrode assembly. The accommodation region has a first width in a center area thereof and a second width in opposing ends thereof, and wherein the second width is greater than the first width. When the case configured to accommodate the electrode assembly is formed, formation errors caused by concentration of stress such as tearing of a raw material or thickness deviations may be prevented.
