<p>Provided is a battery having an air-permeable case capable of increasing cooling performance using air by having the air-permeable case limiting passage of moisture and foreign material but allowing air to freely pass therethrough. The battery having an air-permeable case according to the present invention includes: a stack formed by stacking a plurality of cells in which electrodes are formed; and a case enclosing the stack of the cells, wherein the case has wall surfaces in which a plurality of holes are formed so that an area thereof the hole is at least half of an area of the wall surface. Particularly, the case may include wall surfaces formed in a mesh structure.</p> |
