    Abstract: A secondary battery has an electrode plate, including a current collector, an active material layer and a conductive structure. The current collector includes an insulating layer, first and second conductive layers, and the first conductive layer and the second conductive layer are respectively arranged onto two surfaces of the insulating layer. The first conductive layer has a first body section with a first protruding section connected thereto. The second conductive layer has a second body section with a second protruding section connected thereto. The conductive structure includes a first conductive member connected to the first protruding section and a second conductive member connected to the second protruding section. The second conductive member is bent towards the first conductive member and connected to the first conductive member, and the first conductive member extends away from the active material layer and is beyond the second conductive member.

    Abstract: 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.

    Abstract: A secondary battery includes an electrode assembly including current collecting sections, an electrode terminal, and an adapter sheet connecting the current collecting sections to the electrode terminal. The electrode assembly includes active material layer(s), current collector(s) each including an insulating layer and first and second conductive layers sandwiching the insulating layer, and conductive structures each including first and second conductive members. A portion of the first conductive member extending beyond the second conductive member forms a current collecting section. The current collecting sections are laminated with each other, with one of the current collecting sections directly contacting the adapter sheet. Neighboring ones of the current collecting sections directly contact each other, without any second conductive member arranged therebetween.

    Abstract: The present disclosure relates to a secondary battery and an electrode plate. The electrode plate includes a current collector, an active material layer, a conductive structure, and a first protective layer. The current collector includes an insulating layer and a conductive layer disposed on the insulating layer. The conductive layer includes a main body portion and a protrusion portion. A surface of the main body portion facing away from the insulating layer is covered by the active material layer, while a surface of the protrusion portion facing away from the insulating layer is uncovered by the active material layer. The conductive structure is welded to the protrusion portion and thus a welded zone is formed. The first protective layer has elasticity, and is disposed on a side of the protrusion portion facing away from the insulating layer and is located between the welded zone and the active material layer.
