Abstract: An electrode assembly and a battery are provided. The electrode assembly may be effectively fixed inside a can as a pressure-sensitive adhesive tape attached to an outer circumferential surface of the electrode assembly is formed into a 3D shape by an electrolyte. Thus, the electrode assembly does not move and rotate inside the can due to external vibration or impact and damage of welded regions of a tab or disconnection of inner circuits can be prevented.
