Patent ID: 8748022

Claim:
A battery, comprising: an electrode assembly having a first electrode, a second electrode and a separator between the first electrode and the second electrode, the first electrode, second electrode and separator being wound together around a central region of the electrode assembly; an electrolyte; a pouch accommodating the electrode assembly and the electrolyte; and a fixing member that fixes a winding end of the electrode assembly and an external surface of the electrode assembly, the external surface being closer to the central region than the winding end, wherein: the fixing member includes a base layer and an adhesive layer, the base layer being between the pouch and the adhesive layer, the fixing member contacting the winding end and the external surface of the electrode assembly, a portion of the base layer in contact with the electrolyte is in a melted condition, and the adhesive layer is separated into a first region on the winding end of the electrode assembly and a second region detached from the first region on the external surface of the electrode assembly such that the first region and the detached second region are spaced apart from each other.
