Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A wound-type battery comprising: a wound electrode group that includes a first electrode and a second electrode having a polarity opposite to that of the first electrode; an electrolyte; a battery case that houses the electrode group and the electrolyte; 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; a first tab that passes through the hole to electrically connect the first electrode and the sealing plate to each other; and a second tab that electrically connects the second electrode and the battery case to each other, wherein 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, and the tab tape includes at least a first adhesive layer on a first tab side 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, wherein the second adhesive layer comprises a curable resin composition or a cured product thereof, wherein the curable resin composition is a thermosetting resin composition, and wherein a thickness of the tab tape is 10 μm or more and 200 μm or less. 2. The wound-type battery according to claim 1 , wherein the second adhesive layer has insulating properties. 3. A wound-type battery comprising: a wound electrode group that includes a first electrode and a second electrode having a polarity opposite to that of the first electrode; an electrolyte; a battery case that houses the electrode group and the electrolyte; 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; a first tab that passes through the hole to electrically connect the first electrode and the sealing plate to each other; and a second tab that electrically connects the second electrode and the battery case to each other, wherein 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, and the tab tape includes at least a first adhesive layer on a first tab side 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, wherein the tab tape is disposed so as to cover at least a part of the hole, and at least a part of the tab tape faces the insulating plate, wherein the second adhesive layer comprises a curable resin composition or a cured product thereof, wherein the curable resin composition is a thermosetting resin composition, and wherein a thickness of the tab tape is 10 μm or more and 200 μm or less.
