Abstract
An electrode assembly includes a cathode electrode plate, an anode electrode plate, and a separator disposed between the cathode electrode plate and the anode electrode plate. At least one of the cathode electrode plate and the anode electrode plate is an electrode plate which includes a current collector and a first conductive connector. The current collector includes an insulating layer having opposite side surfaces, a first conductive layer, a second conductive layer, and two electrode active substance layers. The first conductive layer and the second conductive layer are arranged on opposite side surfaces, and the two electrode active substance layers are coated onto the first conductive layer and the second conductive layer. The first conductive connector electrically connects the first conductive layer and the second conductive layer. The electrode assembly is formed by coiling the cathode electrode plate, the separator, and the anode electrode plate.
