| abstract | PROBLEM TO BE SOLVED: To provide a power storage cell capable of reducing the occurrence of a short circuit at an abnormal time. SOLUTION: In a power storage cell 2, in a joint region K between a current collector 22 and a spacer 14, a fragile portion Ka in which the joint strength between the spacer 14 and the current collector 22 is lower than other parts of the joint region K is formed. It is provided from the edge Kb on the formation region side of the active material layer 21 to the edge Kc on the outer edge side of the current collector 22 in the plane direction of the bonding region K. In the fragile portion Ka, one surface 22a of the current collector 22 is a roughened surface R, and the spacer 14 has a melting point higher than the temperature of the gas G generated in the cell at the time of abnormality, and the current collector 22 The first resin portion 31 bonded to each of the one side 22a and the second resin portion 32 having a melting point lower than that of the gas G and arranged so as to be sandwiched between the first resin portions 31. It is configured. [Selection diagram] Fig. 5 |
