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.
Claims18
An electrode assembly having a pressure-sensitive adhesive tape attached to an outer circumferential surface thereof,
- wherein the pressure-sensitive adhesive tape comprises:
- a substrate layer deforming in a longitudinal direction when coming in contact with an electrolyte;
- and
- a pressure-sensitive adhesive layer formed on one surface of the substrate layer in a direction parallel to the longitudinal direction of the substrate layer.
