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 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: A battery module includes a plurality of battery cells each having a safety mechanism, a cell case having a plurality of battery housing parts for housing the plurality of battery cells respectively in a predetermined arrangement, an insulating member disposed on one side of each of the battery cells, and a duct serving as a route for exhausting exhaust gas discharged from the battery cells. The battery housing parts have a plurality of openings for housing the battery cells. The insulating member has a through hole formed at a position facing an opening of the plurality of openings that houses corresponding one of the battery cells, and a lid part for closing an opening of the plurality of openings that houses no battery cell. The exhaust gas is discharged to the route of the duct through the through hole of the insulating member.
