Abstract: A power storage module includes: a plurality of power storage devices arranged in a first direction; and a separator provided between two adjacent power storage devices and insulating the two power storage devices from each other. The power storage device includes an exterior can that have an opening, a sealing plate that blocks the opening, and a joint part between the exterior can and the sealing plate. The separator includes a contact area that abuts a surface of the exterior can facing the first direction and a separation area that overlaps the joint part as viewed in the first direction and concaved with respect to the contact area in a direction away from the exterior can.

Abstract: A power storage module includes at least one power storage device, and a buffer member arranged with the power storage device in a first direction X. The buffer member includes a hard part having a predetermined hardness and a soft part softer than the hard part, the hard part and the soft part receiving a load in first direction X from the power storage device. The hard part changes its shape by receiving a load of a predetermined magnitude or more. The buffer member changes its state, by the hard part changing its shape, from a first state in which the load is received by the hard part to a second state in which the load is received by the soft part.

Abstract: An electrical storage module includes at least one electrical storage device, and a buffer member that is arrayed in first direction X together with the electrical storage device and receives a load in first direction X from the electrical storage device. The buffer member has a soft part and a hard part, which is positioned closer to an outer edge part of the buffer member than the soft part, and the soft part is more easily deformed than the hard part.

Abstract: A battery module includes: a battery stack having a plurality of batteries; a plurality of first restraining members and a plurality of second restraining members; and connecting members. The first restraining members and the second restraining members define a housing space for the battery stack. Each of the first restraining members has a first housing part extending in a direction intersecting a planar direction in which the battery stack, the first restraining members, and the second restraining members are arranged, and each of the second restraining members has a second housing part extending in the planar direction. Each of the connecting members connects each of the first restraining members and each of the second restraining members to each other by being housed in the first housing part of each of the first restraining members and in the second housing part of each of the second restraining members.
