Abstract
A battery module includes a plurality of unit batteries and barriers which are interposed between the unit batteries. The barriers have front surfaces which contact the unit batteries and which are curved to bend elastically. The barriers have side surfaces which interconnect the front surfaces, and which have pathways through which a heat transfer medium flows. Connecting rods and nuts interconnect end plates of the battery module so as to press the unit batteries and the barriers together.

A battery module, comprising:
- a plurality of unit batteries;
- and
- barriers interposed between the unit batteries;
- the unit batteries and the barriers being alternately stacked to constitute a battery set;
- outermost sides of the battery set being closely contacted by corresponding end plates;
- and
- each of said barriers having two front surfaces, each front surface contacting a corresponding one of two adjacent unit batteries, said each front surfaces surface being convexly curved toward said corresponding one of the two adjacent unit batteries, and said each front surface bending elastically;
