Claim 0:
1. A battery module comprising:
a housing comprising a first material;
an electrochemical cell disposed in the housing, the electrochemical cell comprising a first cell surface having electrode terminals and a second cell surface substantially opposite the first cell surface;
a heat sink integral with a portion of the housing and comprising a second material different from the first material, the heat sink having a heat sink surface facing the second cell surface;
a thermally conductive adhesive configured to bond the second cell surface and the heat sink surface, the thermally conductive adhesive comprising a mixture of an epoxy resin and a hardener, with the epoxy resin having a viscosity between approximately 40,000 centipoise (cP) and approximately 50,000 cP at 25 degrees centigrade and with the hardener having a second viscosity of between greater than 35,000 cP and 50,000 cP at 25° C.; and
the thermally conductive adhesive having a bonding shear strength and a bonding tensile strength between the electrochemical cell and the heat sink of between approximately 5 megaPascals (MPa) and approximately 50 MPa at 25 degrees Celsius.
