Electrode plate including current collector having conductive layer disposed on insulating layer and protective layer disposed on condutive layer, and battery including the same
The present disclosure provides a secondary battery and an electrode plate. The electrode plate includes a current collector, an active material layer, and a first protective layer. The current collector includes an insulating layer and a conductive layer disposed on the insulating layer. The conductive layer has a main body portion covered by the active material layer and a protrusion portion uncovered by the active material layer. The first protective layer is disposed on a side of the protrusion portion facing away from the insulating layer. The electrode plate further includes a conductive structure, which has a connecting portion fixed on the main body portion, and a first extending portion exceeding an end of the protrusion portion away from the main body portion. The first protective layer is disposed on a side of the connecting portion close to the active material layer along a height direction.
