Title:
BATTERY AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2024/062776
Kind Code:
A1
Abstract:
A battery (1) comprises: a power generation element (5) in which a plurality of battery cells (100) and a plurality of current collectors are laminated; a plurality of electrode conductive connection parts (21); and an electrode conductive extraction layer (41). The plurality of current collectors include: electrode current collectors (140); and counter electrode current collectors (150). Each of the plurality of electrode conductive connection parts (21) is connected to a different electrode current collector (140) in a first region on a side surface of the power generation element (5). The electrode conductive extraction layer (41) is electrically connected to each of the plurality of electrode conductive connection parts (21) in the first region. In a plan view of the first region, the length (Lb1) of the plurality of electrode conductive connection parts (21) in the direction orthogonal to the lamination direction of the power generation element (5) is longer than the length (La1) of the electrode conductive extraction layer (41) in the direction orthogonal to the lamination direction of the power generation element (5).
