    Abstract: This application provides embodiments including a connection member and a rechargeable battery. The connection member includes a guide plate and a first connecting plate integrally formed on the guide plate, where the first connecting plate is disposed in a bendable manner relative to the guide plate, and at least one indentation is present between the first connecting plate and the guide plate. In the embodiments, a bending position is more accurate when the first connecting plate is bent relative to the guide plate. This is conducive to an accurate size of the connection member being bent, and is also helpful for the rechargeable battery to successfully assemble a battery core, the connection member, and a housing.
