Abstract
Disclosed herein are an electrode assembly and a composite electrode assembly mounted in a battery case of a secondary battery. The electrode assembly and the composite electrode assembly have a stair-like structure. The stair-like structure is formed based on the curvature of a device to utilize a dead space of the device, thereby improving the capacity of the device per unit volume.
