The end cap assembly includes an end cap, an electrode terminal and a connector. The end cap is provided with an electrode lead-out hole which penetrates the end cap in a thickness direction of the end cap. The connector is configured to connect the end cap to fix the electrode terminal. The electrode terminal is provided opposite to the electrode lead-out hole, and a projection of the electrode terminal in the thickness direction does not overlap with a projection of the end cap in the thickness direction, thus a radial size of the electrode terminal is smaller, which reduces the space occupied by the electrode terminal, saves material and has better economy.
