Abstract
A battery cell is configured such that a jelly-roll type electrode assembly is accommodated in a battery casing, and includes: the battery casing including upper, lower, and side surfaces, wherein the side surface of the battery casing includes an isolation wall providing a buffer space between the battery casing and the electrode assembly. The buffer space accommodates deformation of the electrode assembly when the electrode assembly is expanded, such that deformation of the side surface of the battery casing is prevented from occurring.
