Japanese Patent JP7014689

B2

To provide a power storage module with improved reliability and a manufacturing method for the power storage module.SOLUTION: A power storage module 4 includes an electrode laminate 11 including a plurality of electrodes, a metal plate 50, and a first sealing portion 21. The plurality of electrodes include a plurality of bipolar electrodes 14 and a negative electrode termination electrode 18. The electrode includes an electrode plate 15 including a first surface 15a and a second surface 15b. The negative electrode termination electrode 18 further includes a negative electrode 17 provided on the second surface 15b, and is disposed between the bipolar electrode 14 and the metal plate 50. A first resin portion 21A is welded to a peripheral portion of the first surface 15a of the negative electrode termination electrode 18. The metal plate 50 includes a third surface 50a and a fourth surface 50b, and is welded to the first resin portion 21A at the peripheral portion of the third surface 50a. A second resin portion 51 is welded to the peripheral portion of the fourth surface 50b of the metal plate 50. A water-repellent material 60 is provided on at least a part of the surface of the second resin portion 51.SELECTED DRAWING: Figure 2
