<p><P>PROBLEM TO BE SOLVED: To provide a battery pack having superior output characteristics, by reducing the internal resistance difference between the cathode and the anode of each battery, which is constituted by serially connecting a plurality secondary batteries. <P>SOLUTION: In the battery pack 100 has a plurality of unit batteries 20, connected and arrayed in series, capable of charging and discharging, each consisting of an electrode body having an cathode and an anode, a case 50 housing the electrode body, and a cathode terminal 60, as well as, an anode terminal 62 which is electrically connected to the cathode, as well as, the anode, respectively, arranged outside the case, regarding at least a pair of unit batteries laid adjacent in the arraying direction, a Peltier element 10 is arranged in between a cathode terminal of either a unit battery or the anode terminal of the other facing the cathode terminal, so that when a direct current is passed to the element, the cathode terminal of one unit battery is heated, while the anode terminal of the other unit battery is cooled. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
