Electrode Component, Electrode Assembly And Rechargeable Battery

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.
