Abstract
Disclosed herein is a battery cell having an electrode assembly mounted in a variable cell case in a state in which the electrode assembly is impregnated with an electrolyte, the battery cell being configured to be flexibly deformed in response to the shape of a device, in which the battery cell is mounted, wherein an uppermost end electrode and/or a lowermost end electrode of the electrode assembly in the direction in which electrodes are stacked is provided on an electrode current collector thereof, facing the inner surface of the cell case, with an electrode mixture including inert particles, 10 to 100% of the inert particles being distributed on the surface of the electrode mixture such that a concave-convex structure is formed in the surface of the electrode mixture in vertical section.
