Electrode member, electrode assembly and rechargeable batter
The present disclosure relates to the technical field of rechargeable battery and, particularly, relates to an electrode member, an electrode assembly and a rechargeable battery. The electrode member includes an electrode body and a conduction structure, the electrode body comprises an insulation substrate and an conduction layer placed on a surface of the insulation substrate, the conduction layer includes a first portion and a second portion extending from the first portion, the first portion is coated with an active material while the second portion is not coated with the active material, and the conduction structure is connected to the second portion. After the electrode assembly is formed by winding or stacking of the electrode members, adjacent current guide portions are electrically connected to one another by the conduction structure, without being limited by the insulation substrate, so that the conductivity of the electrode member is effectively improved.
