Patent ID: 8293397

Claim:
A battery assembly, comprising: a plurality of single-battery cells being formed as a rectangular parallelepiped configuration; a plurality of thermally-conductive members having a plated configuration and being formed of a material selected from the group consisting of rubber and thermoplastic elastomer that is mixed with a sufficient amount of highly thermally-conductive material for providing the thermally-conductive members with a thermal-conductivity of 5 W/m·K or more, the thermally-conductive members exhibiting an Askar C hardness of 50 or less and electric insulatability; the battery assembly being made by contacting the single-battery cells and the thermally-conductive members to each other, disposing them one after another alternately in a row, and binding them by means of pressurizing them on both ends thereof in opposite directions to a direction of disposing them one after another alternately in a row; the thermally-conductive members comprising a contact surface, to which a largest-area side surface of the single-battery cells contacts, and a radiation surface, which is exposed to a radiation space; and the single-battery cells being cooled indirectly by cooling the radiation surfaces of the thermally-conductive members, wherein the battery assembly is free of any clearance or gap between the respective single-battery cells and the thermally-conductive members.
