Summary: | PROBLEM TO BE SOLVED: To provide a battery pack capable of showing high battery performance by having longer cycle life than existing battery pack. SOLUTION: Electrical resistance between unit cells (20B and 20C) adjacent in the vicinity of the center in the length direction of a module is set lower than electrical resistance between unit cells (20A and 20B, 20C and 20D) adjacent in the vicinity at both ends of a battery module 2. Concretely, a flat tab 10B connecting unit cells 20B and 20C is made thicker than flat tabs 10A, 10C connecting between unit cells 20A and 20B, and between 20C and 20D. COPYRIGHT: (C)2006,JPO&NCIPI |
