MODULE STRUCTURE OF BIPOLAR SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a bipolar secondary battery module with an insulation property secured at an end part.

SOLUTION: In the bipolar secondary battery module 10 made by sealing with a bipolar secondary battery element 21 laminating in series at least two layers of bipolar electrodes 16 with a cathode 13 formed on one face of a collector 11 and an anode 15 formed on the other with an intercalation of an electrolyte layer 17 in an outer package material 29, a member 31 with a tensile stress higher than that of the outer package material 29 is inserted between the bipolar secondary battery element 21 and the outer package material 29.
