Abstract: A battery module includes a plurality of battery blocks. Each battery block includes: a cell assembly including a plurality of cells; a block holder for holding the cell assembly; and a metal plate. The plurality of cells are held in the block holder while the positive electrodes and negative electrodes of the cells are aligned. A projection or the metal plate is disposed outside the block holder. The tip of the projection of one of adjacent battery blocks is in contact with the metal plate of the other.

Abstract: A wound-type battery includes a wound electrode group having a first electrode and a second electrode with polarity opposite to the first electrode, an electrolyte, a battery case, a sealing plate that seals an opening of the battery case, an insulating plate that is disposed between the electrode group and the sealing plate and that has a hole, and a first tab that passes through the hole to electrically connect the first electrode and the sealing plate to each other. At least a part of a region of the first tab that extends through the hole to a sealing plate side is covered with a tab tape on a side facing the insulating plate. The tab tape includes at least a first adhesive layer and a second adhesive layer on a side opposite the first adhesive layer and is in contact with the first tab through the first adhesive layer.

Abstract: A battery module includes a partition wall to separate an upper space from a lower space, a first plate that defines the upper space together with the partition wall, and a second plate that is disposed above the first plate such that a gap is left between the first and second plates. A case has an opening that is formed to let the gap communicate with an outside of the case. The first plate has a through hole through which the upper space and the gap communicate. The battery module further includes a through path passing through the partition wall and each of the plates to let the lower space communicate with a space above the second plate. The upper space and the gap constitute an exhaust duct, while the lower space and a top space constitute a cooling duct.

Abstract: A battery module includes a plurality of cylindrical batteries that each include a safety valve surrounded by an annular breaking portion configured to break when internal pressure of each of the batteries exceeds a predetermined level. The battery module further includes an exhaust duct to guide gas emitted from the cylindrical battery to outside the module when safety valve is opened, and a gas direction regulator component disposed between the cylindrical batteries and the exhaust duct. The gas direction regulator component has a plurality of openings to expose the respective safety valves. Portions of the gas direction regulator component overhang areas overlapping the respective safety valves so as to cover an end of each safety valve opposite another end of each safety valve adjacent to an exit of the exhaust duct.

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.
