<p><P>PROBLEM TO BE SOLVED: To effectively suppress temperature rise in a plurality of unit cells which are housed inside a battery case. <P>SOLUTION: The battery pack is provided with a battery case 2; a plurality of unit cells 3 housed in the battery case 2 and laminated and connected with each other in series; a positive-side current collector plate 4, connected to the positive electrode of the endmost unit cell of the plus side out of the plurality of the unit cells 3; a negative-side current collector plate 4, connected to a negative electrode of the endmost unit cell of the negative side out of the plurality of the unit cells 3; and a heat-radiating partitioning plate 1, made of an aluminum base material having a heat-treated coating and partitioning between neighboring unit cells. The heat-radiating partitioning plate 1 is pinched by the positive electrode of the unit cells 3 and the neighboring negative electrode of the unit cells 3. and is provided with one or more of ventilation holes D, in a direction of crossing the pinching direction. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
