Document Type and Number:
Japanese Patent JP2019186117
Kind Code:
A
Abstract:
To provide a power storage device capable of improving vibration resistance, and to provide a manufacturing method of a power storage device.SOLUTION: A power storage device includes a cell stack including multiple power storage cells laminated alternately via a positive electrode collector plate 15 and a negative electrode collector plate 16, a positive electrode bus bar 4 extending in the lamination direction, and joined to the positive electrode collector plate 15 in the height direction, and a negative electrode bus bar 5 extending in the lamination direction, and joined to the negative electrode collector plate 16 in the height direction. Each of the multiple power storage cells has multiple bipolar electrodes laminated in the lamination direction, and a holding member for holding the multiple bipolar electrodes, the positive electrode bus bar 4 has a protrusion 41 for locking the holding member 9A of a power storage cell 7A, out of the multiple power storage cells, and the holding member 9A has a recess 91A facing the protrusion 41 in the width direction.SELECTED DRAWING: Figure 7
