Document Type and Number:
WIPO Patent Application WO/2020/083278
Kind Code:
A1
Abstract:
The present application provides a current collecting member, a secondary battery, and a manufacturing method for the secondary battery. The secondary battery comprises an electrode assembly, a housing, a top cover assembly, and a current collecting member. The electrode assembly is received in the housing, and comprises a main body and a first tab. The first tab extends from one end, in the lateral direction, of the main body. The top cover assembly comprises a top cover plate and a first electrode terminal provided on the top cover plate. The top cover plate is connected to the housing. The current collecting member connects the first tab and the first electrode terminal. The current collecting member comprises a base plate and a support plate. The base plate is disposed on one side, in the lateral direction, of the main body and extends in a direction perpendicular to the lateral direction. The support plate extends from the outer end, in the longitudinal direction, of the base plate and is folded back to the side of the base plate distant from the main body. The support plate comprises a bent portion and a connecting portion. The bent portion is connected to the base plate and is bent into an arc. The connecting portion extends from the end of the bent portion distant from the base plate. The first tab is connected to the connecting portion and is bent along the surface of the bent portion.
