The invention discloses a leading-out connector of anode and cathode terminals of a valve-control storage battery. A screw hole is arranged at the upper end of a high-cap nut, symmetrical expansion seams are vertically arranged on the middle and lower walls of the high-cap nut, four holes are evenly arranged on the same circumference on the wall at the upper end of the expansion seams, the diameter of the inner wall at the lower end of the expansion seam is slightly larger than that of a terminal of the storage battery, and penetrating holes are arranged on the same diameter of the same circumference on the wall of the lower end part of the expansion seam; when the leading-out connector is used, a wire-pressing bolt penetrates into the screw hole, and a wire is tightly pressed at the upper end of the high-cap nut directly or through a spacer; the lower end of the high-cap nut is sleeved on the anode terminal or the cathode terminal of the storage battery, and a long screw rod penetrates into the penetrating hole on the wall of the lower end part of the high-cap nut, locked and fixed by a nut, a spring spacer and a spacer. The leading-out connector can connect wires firmly, can notslide off easily, and is convenient to use when used to replace the lag storage battery. The invention greatly shortens the replacing time, reduces the workload, the labor intensity and the using safety risks, improves the working efficiency and the direct-current system operation, and is light in weight and portable in carrying.

The invention discloses a lithium battery having a fire-proof and explosion-proof device. The lithium battery includes a cell set, a cell protective sheath and an external shell. The cell set is arranged in the cell protective sheath and the cell protective sheath is disposed in the external shell. A clearance between the cell protective sheath and the external shell is filled with a fire extinguish material which can be subject to an endothermic reaction and generates carbon dioxide. The external shell is provided with a discharging hole. In the device, during a use process of the lithium battery, the fire extinguish material, which can be subject to an endothermic reaction when being heated and generates carbon dioxide, is used as a working medium for performing heat absorption and oxygen insulation to the battery. In addition, an internal pressure of the battery can be regulated timely. By the comprehensive protective method above, accidents, such as ignition, explosion and the like, can be effectively prevented so that safe risk of the lithium battery can be greatly reduced.

The invention discloses a lithium battery with a fireproof and explosion-proof device. The lithium battery includes a battery pack, a battery sheath and a shell, the battery pack is placed in the battery sheath, and the battery sheath is placed in the shell. A heat insulating layer is arranged between the inner surface of the shell and the cell sheath, the gap between the cell sheath and the heat insulating layer is filled with fire extinguishing material, and dredging holes are provided on the shell. During the use of lithium batteries, this device uses fire extinguishing materials that can undergo endothermic reactions and generate carbon dioxide when heated as the working medium to absorb heat and isolate oxygen for the batteries, and can adjust the internal pressure of the batteries in time. By adopting the above comprehensive protection methods, It can effectively prevent accidents such as fire and explosion, and greatly reduce the safety risk of battery use.
