Abstract
A lithium secondary battery case composed of laminate sheet including an outer layer/barrier layer/inner layer structure is provided. The case includes a first region in which gas discharge is easier or expansion is relatively easier compared to a second region. The second region is a remaining region that excludes the first region. The laminate sheet forms the first region by either not including the barrier layer or including a barrier layer having a slit therein.
