Summary: | To provide a battery capable of increasing a space that a plurality of electrode groups in an internal cavity of an outer container occupy in a configuration where collector tabs of the plurality of electrode groups protrude toward a side on which a lid member is located.SOLUTION: A battery comprises an outer container 3, a lid member 5, a plurality of electrode groups 2A and 2B, first leads 23A, second leads 23B, and electrode terminals 21. The lid member 5 covers an opening of an internal cavity of the outer container 3. The plurality of electrode groups 2A and 2B are housed in the internal cavity of the outer container 3. In a first electrode group 2A, each first collector tab 17A protruding toward a side on which the lid member 5 is located is bonded with each first lead 23A. In a second electrode group 2B different from the first electrode group 2A, each second collector tab 17B protruding toward a side on which the lid member 5 is located is bonded with each second lead 23B different from the first lead 23A. Each electrode terminal 21 exposed on an outer surface of the lid member 5 is connected with the first lead 23A and the second lead 23B together.SELECTED DRAWING: Figure 2
【課題】蓋部材が位置する側へ複数の電極群の集電タブが突出する構成において、外装容器の内部空洞における複数の電極群が占めるスペースを大きくすることが可能な電池を提供する。【解決手段】実施形態の電池は、外装容器3、蓋部材5、複数の電極群2A,2B、第1のリード23A、第2のリード23B及び電極端子21を備える。蓋部材5は、外装容器3の内部空洞の開口を塞ぎ、複数の電極群2A,2Bは、外装容器3の内部空洞に収納される。第1の電極群2Aにおいて蓋部材5が位置する側へ突出する第1の集電タブ17Aは、第1のリード23Aに接合され、第1の電極群2Aとは別の第2の電極群2Bにおいて蓋部材5が位置する側へ突出する第2の集電タブ17Bは、第1のリード23Aとは別体の第2のリード23Bに接合される。蓋部材5の外表面おいて露出する電極端子21には、第1のリード23A及び第2のリード23Bが一緒に接続される。【選択図】図2 |
