    摘要： A battery pouch that is formed to accommodate an electrode assembly, comprising: a first member layer; and a second member layer that is located between the first member layer and the electrode assembly, and contains an elastomer and protrudes toward the electrode assembly at a plurality of locations to be brought into discontinuous contact with the electrode assembly, wherein the second member layer has spaces open to the electrode assembly between the protruding portions. Accordingly, the power output characteristics of the battery can be improved and the damage to the damage to the sealing portion can be prevented.
