Title:
角形密閉二次電池及び角形密閉二次電池の製造方法
Document Type and Number:
Japanese Patent JP5583421
Kind Code:
B2
Abstract:
A prismatic sealed secondary cell that is excellent in current collection efficiency and current collection stability, and capable of high output discharge. In the prismatic sealed secondary cell a laminate-type or a wound laminate-type flat electrode assembly is housed in a prismatic cell case, a pair of current collector plates are disposed on a flat portion of the outermost surface of the core exposed portion of the first electrode plate constituting the flat electrode assembly so that the pair of current collector plates sandwich the flat portion in the thickness direction, and a columnar connection conductive member is interposed between two-divided core exposed portion laminates in the flat portion sandwiched between the pair of current collector plates, and the pair of current collector plates, the columnar connection conductive member and the two-divided core exposed portion laminates are welded to each other.
