Zusammenfassung: | To provide a battery capable of widening the width of a positive electrode tab and a negative electrode tab to improve conductivity, and suppressing an increase in the size of the battery.SOLUTION: A battery 100 comprises: an outer package (laminate case 20) including a positive electrode, a negative electrode, and a laminate film, in which the positive electrode and the negative electrode are housed; a positive electrode tab 15 electrically connected to the positive electrode, and projected from one side 21 side of the outer package to the outside; a negative electrode tab 16 electrically connected to the negative electrode, and projected from one side 21 side of the outer package to the outside; a positive electrode tab sealant 31 provided between the outer package and the positive electrode tab 15 to cover the positive electrode tab 15; and a negative electrode tab sealant 32 provided between the outer package and the negative electrode tab 16 to cover the negative electrode tab 16. A part of the positive electrode tab sealant 31 and a part of the negative electrode tab sealant 32 are overlapped with each other in a region between the positive electrode tab 15 and the negative electrode tab 16.SELECTED DRAWING: Figure 2
【課題】正極タブおよび負極タブの幅を広くして通電性を向上させることができ、かつ、電池の大型化を抑制することができる電池を提供する。【解決手段】電池100は、正極と、負極と、ラミネートフィルムを含み、正極および負極を内部に収容した外装体(ラミネートケース20)と、正極と電気的に接続され、外装体の一辺21側から外側に突出している正極タブ15と、負極と電気的に接続され、外装体の上記一辺21側から外側に突出している負極タブ16と、外装体と正極タブ15との間に設けられ、正極タブ15を被覆している正極タブシーラント31と、外装体と負極タブ16との間に設けられ、負極タブ16を被覆している負極タブシーラント32とを備える。正極タブ15と負極タブ16との間の領域において、正極タブシーラント31の一部と、負極タブシーラント32の一部は重なり合っている。【選択図】図2 |
