  • Publication number: 20190221821
    Abstract: The present disclosure provides a component for collecting a current and a battery. The component for collecting a current comprises an introducing body and a connection body bendably arranged relative to the introducing body. The introducing body comprises a holding arrangement. The holding arrangement is used for fixing the introducing body when the connection body is bent. When the connection body is bent, an operator can use a clamping tool to fixedly clamp the holding arrangement arranged on the introducing body, so that the stress applied on the component for collecting a current can be transferred to the position of the clamping tool when the connection body is bent, thereby reducing the stress from damaging electrode assemblies.

  • Publication number: 20180166676
    Abstract: A power battery and a power battery top cap structure for a power battery are provided. The power battery top cap structure includes first and second electrode assemblies, a lower insulation member, a top cap piece, and an abutment member. Both the first and second electrode assemblies are fixed on the top cap piece. The lower insulation member is fixed below the top cap piece. The lower insulation member includes, along an X axis, a snapping portion and a connecting portion. The abutment member extends along a Y axis and abuts between the connecting portion and the top cap piece so that a minimum distance between the connecting portion and the top cap piece along the Z axis is G3, where G3>0.
