The invention discloses a close cell with explosion-resistant function, which includes a cell cylinder, a cell unit contained in the cell cylinder, end cap elements for sealing two ends of the cell cylinder. The end cap elements are respectively connected with anode and cathode of the cell unit, the end cap element of one end is equipped with a explosion-resistant device, wherein the end cap element equipped with the explosion-resistant device is directly connected with the cell cylinder, a insulated layer is arranged between the end cap element of the other end and the cell cylinder. Because the insulated layer is arranged between the end cap element without explosion-resistant structure and the cell cylinder, the end cap element with the explosion-resistant structure can be directly connected width the cell cylinder, so that, a insulated layer is not needed to arrange between the end cap element with the explosion-resistant structure and the cell cylinder, structure of the end cap element is simplified, limitation of cell cylinder intensity is resolved, aluminum alloy cylinder with small intensity can also employ the structure, sealing difficulty and weight of cell is greatly reduced. |
