METHOD FOR MANUFACTURING LAMINATE TYPE BATTERY

To suppress a worsening of a performance of a laminate type battery while preventing an electrode plate from being out of position.SOLUTION: A laminate type battery comprises: an outer packaging body; a membrane-electrode assembly having a plurality of first electrode plates and a plurality of second electrode plates which are laminated to alternate in a laminating direction; and a first tab disposed on one side of the membrane-electrode assembly. The first electrode plates include a first electrode current collector including a first connection region and a first effective region which are adjacent to each other, and a first electrode active material layer provided in the first effective region, the plurality of the first connection regions are superposed on each other to form a first connection part, and the first tab is joined to the first connection part. The first connection part includes a first fixing part provided at a location different from that of the first tab when viewed from the laminating direction, and the first connection regions are fixed to each other in the first fixing part.SELECTED DRAWING: Figure 3 【課題】電極板の位置ずれを防止しつつ、積層型電池の性能低下を抑制する。【解決手段】積層型電池は、外装体と、積層方向に交互に積層された複数の第１電極板および複数の第２電極板を有する膜電極接合体と、膜電極接合体の一側に配置された第１タブと、を備える。第１電極板は、互いに隣接する第１接続領域および第１有効領域を含む第１電極集電体と、第１有効領域に設けられた第１電極活物質層と、を含み、複数の第１接続領域が重ね合わされて第１接続部が形成され、第１タブは、第１接続部に接合されている。第１接続部は、積層方向で見たときに第１タブとは異なる位置に設けられた第１固定部であって、第１接続領域の各々が互いに固定された第１固定部を含む。【選択図】図３
