Abstract: An electrode member includes a substrate portion formed of a metal thin plate, a connection portion connected to the electrode terminal of a cell, and a fuse for electrically connecting the substrate portion to the connection portion. In the plane orthogonal to the longitudinal direction of the cell, the length of the fuse is greater than the width of the connection portion.

Abstract: A cell module includes a plurality of battery cells each having a safety valve at a first end in a height direction, a first current collector plate including a main body having a through hole that at least partly overlaps the safety valve when viewed along the height direction and a lead extending into the through hole from the main body and being electrically connected to a first terminal of each of the battery cells, an exhaust duct disposed over a surface of the first current collector plate remote from the battery cells, and an insulating film being made of an insulating material and covering an area of the first current collector plate facing the exhaust duct. The safety valve opens when an internal pressure of any of the battery cells reaches or exceeds a predetermined level.

Abstract: A battery module includes a battery and a covering put over a surface of the battery. The surface of the battery is provided with a valve to release gas produced inside the battery. The covering includes a thin-walled part and a thick-walled part disposed in a region contiguous to the thin-walled part. The thin-walled part is formed thinner in thickness than the thick-walled part.

Abstract: A battery can has a cylindrical body section, an opening section at one end of the body section, and a bottom section closing the other end of the body section. An annularly grooved portion is formed by constriction near the open end of the opening section. The annularly grooved portion has an upper-groove section as the section closer to the open end than the narrowest section, which is positioned farthest inside, of the grooved portion, and also has a lower-groove section as the section closer to the bottom section than the narrowest section. The wall thickness T1 of the lower-groove section is larger than the wall thickness T2 of the body section.

Abstract: Cells are arranged in a predetermined arrangement and are held by holding unit. The holding unit includes a first holding unit, a second holding unit, and a third holding unit. The first holding unit holds cells so as to partially cover the one side of the outer peripheral surfaces of the cells in the longitudinal direction. The second holding unit holds the cells so as to partially cover the other side of the outer peripheral surfaces of the cells in the longitudinal direction. The third holding unit holds the cells so as to cover a region that is covered with neither the first holding unit nor the second holding unit, of the outer peripheral surfaces of the cells in the longitudinal direction.

Abstract: A battery module includes a battery assembly and a thermally-conductive member to hold or support battery assembly. The battery assembly has a plurality of first batteries and a plurality of second batteries that are alternately stacked. The thermally-conductive member includes a first component and a second component that are each disposed along a stacking direction of the batteries. The first component has a heat resistance to the second batteries higher than to the first batteries. The second component has a heat resistance to the first batteries higher than to the second batteries.
