    Abstract: The present disclosure relates to an electrode component, an electrode assembly and a rechargeable battery. The electrode component includes an electrode body, a conductive structure, and a reinforcement structure. The electrode body includes an insulating substrate and a conductive layer disposed on surfaces of the insulating substrate, the conductive layer includes a first portion coated with an active material and a second portion extending from the first portion and uncoated with the active material. The conductive structure is connected to the second portion. The reinforcement structure reinforces the conductive structure on the second portion. According to the present disclosure, by reinforcing the conductive structure connected to the second portion of the electrode component having the insulating substrate by the reinforcing structure, the reliability of the arrangement of the conductive structure on the second portion can be effectively improved.

    Abstract: A rechargeable battery includes a battery core and a connection member. The connection member includes a guide plate and a first connecting plate integrally formed on the guide plate and connected to a tab of the battery core. 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. The tab extends from a side of a core body of the battery core in a width direction. At least a portion of the guide plate protrudes, relative to the first connecting plate, towards the core body of the battery core to form a protrusion, and the protrusion abuts against the battery core.
