<P>PROBLEM TO BE SOLVED: To provide a battery pack which securely suppresses deterioration of battery performance after charging/discharging at a high rate, and to provide a manufacturing method of the battery pack. <P>SOLUTION: In the battery pack 200, a plurality of unit batteries 100 having square battery cases 10 are arranged in a line, and the respective unit batteries 100 are loaded in an arraying direction (Z direction). Two spacers 81 and 82 and a cooling plate 83 are disposed between the unit batteries 100 and 100 constituting the battery pack 200, and a flat surface of the unit battery 100 with which the spacers 81 and 82 are brought into close contact is depressed with loading by a restricting band 73. To put it concretely, the spacer 81 depresses a region including an end of a positive electrode collector terminal 31 side in a power generation region in the flat surface, and the spacer 82 depresses a region including an end of a negative electrode collector terminal 32 side in the power generation region. <P>COPYRIGHT: (C)2013,JPO&INPIT |
