Abstract: A battery includes an electrode plate assembly. An electrode plate assembly includes an electrode plate and a conduction element. The electrode plate includes a current collector. The current collector includes a first conductive material layer, an insulating material layer, and a second conductive material layer. The current collector is provided with a through opening. The conduction element includes a first conduction part, a second conduction part, and a third conduction part. The first conduction part is disposed on a first side of the current collector and electrically connected to the first conductive material layer. The second conduction part is disposed on a second side of the current collector and electrically connected to the second conductive material layer. The third conduction part is disposed at the through opening and electrically connected to both the first conduction part and the second conduction part.

Abstract: An electrode assembly, including a positive electrode plate, a negative electrode plate, a separator, a positive electrode tab. The positive electrode plate includes a positive electrode current collector and a positive electrode active substance layer, the negative electrode plate includes a negative electrode current collector and a negative electrode active substance layer disposed on surface of the negative electrode current collector. The positive electrode active substance layer is provided with a first groove. The negative electrode active substance layer is provided with a second groove, the second groove is corresponding to the first groove, the second groove extends along a thickness direction of the electrode assembly to the negative electrode current collector. The second groove is provided with a first protective adhesive inside, so as to ensure thickness consistency between the groove and a body zone of the electrode plate and reducing the risk of short circuit.
