Title:
双極型二次電池
Document Type and Number:
Japanese Patent JP7190314
Kind Code:
B2
Abstract:
To stably detect a voltage of a single cell even in a case where exfoliation of a cathode collector or an anode collector with respect to an insulation member occurs.SOLUTION: A bipolar secondary battery 10 comprises a battery element 11 in which single cells 20 are stacked. The single cell includes a cathode 30a, an anode 30b, a separator 40 and an insulation member 50. The bipolar secondary battery comprises a voltage detection terminal 70 which is disposed, in an outer periphery of the battery element, between a front face of a cathode collector 31a at a side not in contact with the insulation member between both front and rear faces thereof and a front face of an anode collector 31b at a side not in contact with the insulation member between both front and rear faces thereof, and detecting a voltage of the single cell. The bipolar secondary battery comprises an adhesive layer 80 for bonding any one collector of the cathode collector 31a and the anode collector 31b with the voltage detection terminal.SELECTED DRAWING: Figure 4B
