Japanese Patent JP7014688

B2

To provide a power storage module capable of inhibiting an electrolyte from leaking out of the power storage module due to an alkali creep phenomenon.SOLUTION: A power storage module 4 includes an electrode laminate 11, a sealing body 12 that is provided so as to surround a side surface 11a of the electrode laminate 11, forms an internal space V between adjacent electrodes, and seals the internal space V, and an electrolytic solution containing an alkaline solution housed in the internal space V, and the sealing body 12 includes a frame-shaped first sealing portion 21 arranged between adjacent electrodes and coupled to an edge 15c of the electrode plate 15 of the electrode, and the electrode plate 15 of the negative electrode termination electrode 18 and the first sealing portion 21 are bonded to each other by a frame-shaped first coupling region K1 and a frame-shaped second coupling region K2 surrounding the outside of the first coupling region K1 at a predetermined interval, and a surplus space VC is formed between the first coupling region K1 and the second coupling region K2.SELECTED DRAWING: Figure 3
