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.
