摘要： 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.
