Claim 11:
12. A battery module, comprising:
a plurality of electrochemical cells secured to a heat sink coupled to a housing of the battery module, wherein the heat sink extends in at least one direction to an outermost dimension of the housing, and wherein each electrochemical cell of the plurality of electrochemical cells is in secured connection with the heat sink; and
a thermally conductive adhesive positioned at an interface between the plurality of electrochemical cells and the heat sink, wherein;
the thermally conductive adhesive comprising 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 providing for the secured connection of the plurality of electrochemical cells with the heat sink at the interface, with the thermally conductive adhesive having a bonding shear strength and a bonding tensile strength between the plurality of electrochemical cells and the heat sink of between approximately 5 megaPascals (MPa) and approximately 50 MPa at 25 degrees Celsius.
