ELECTRODE CONNECTION STRUCTURE OF SECONDARY SHEET BATTERY, AND SECONDARY BATTERY WITH THE ELECTRODE CONNECTION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide an electrode connection structure of a secondary sheet battery capable of efficiently dissipating heat in the electrode of the secondary battery from an electrode lead and also capable of realizing electrically and mechanically high connection strength, and a secondary battery with the electrode connection structure.

SOLUTION: The secondary sheet battery 10 comprises a pair of internal poles, a deformable bag-like surrounding body 2 sealingly storing the pair of internal electrodes and electrolyte therein, and positive and negative poles 3a and 3b. In this electrode connection structure, metallic plate-like bus bars 6a and 6b are connected, on the outside of the bag-like surrounding body 2, to leads 3a and 3b of one or more than one secondary sheet batteries 10 connected in series or parallel with each other.
