A rechargeable battery assembly is disclosed. The rechargeable battery assembly holds rechargeable battery cells. The battery cells are oriented so as to have all of the positive terminals at the one end of the assembly and the negative terminals at the other end. The positive and negative terminals are respectively connected together by positive and negative tabs, which have connection holes substantially equidistant from each of the positive and negative terminals of the battery cells. In some embodiments, multiple assemblies are connected to form a battery pack.

Rechargeable battery assembly and pack including the same

A battery module that has improved cooling efficiency includes a plurality of rechargeable batteries and a cooling wall that is installed between the rechargeable batteries to cool the rechargeable batteries, wherein the cooling wall includes first wall bodies that are connected in a first direction and second wall bodies that are connected in a second direction intersecting the first direction, flow paths in which a coolant moves are formed within the first wall bodies and the second wall bodies, and the flow path of the first wall bodies is communicated via the flow path of the second wall bodies.

Battery module

A secondary battery includes a can into which an electrode assembly is inserted, a cap assembly mounted to an opening of the can; and an electolyte injection hole formed on at least one of the can and cap assembly, and safety member to close the electolyte injection hole. The electolyte injection hole is formed on a negative portion of the cap assembly. The safety member is inserted into and welded on the electolyte injection hole.
