The invention discloses a flame-proof and explosion-proof lithium battery protection plate, and relates to the technical field of lithium battery protection devices. The flame-proof and explosion-proof lithium battery protection plate comprises a lithium battery lower protection shell, a detachable lithium battery upper protection shell is assembled at the top of the lithium battery lower protection shell, and a cooling mechanism convenient for cooling the lithium battery is assembled in the lithium battery lower protection shell. Through mutual cooperation of a first reset elastic element, a lithium battery fixing bottom plate, a second reset elastic element and a damping linkage arm, the device can conveniently carry out damping protection on a lithium battery, internal pole piece dislocation caused by falling or collision of the lithium battery is avoided, then spontaneous combustion explosion of the lithium battery caused by external force is avoided, through mutual cooperation of the lithium battery upper protection shell, a temperature monitoring element, a flame-retardant explosion-proof mechanism and fire extinguishing dry powder, the device can conveniently extinguish fire disasters caused by spontaneous combustion of the lithium battery, explosion caused by spontaneous combustion of the lithium battery is avoided, and the safety of using the lithium battery is further improved.
Description
technical field [0001] The invention belongs to the technical field of lithium battery protection devices, and in particular relates to a lithium battery protection board used for flame and explosion protection. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as positive and negative electrode materials and uses non-aqueous electrolyte solution. Lithium batteries are widely used in various industries due to their long life, high storage energy density, high power capacity, and low self-discharge rate. However, due to the very active chemical properties of lithium metal, the normal working temperature of lithium batteries needs to be controlled at -20°C to 60°C. Dislocation of internal pole pieces caused by high temperature environments and drops will cause lithium batteries to spontaneously ignite or explode. Based on the above problems Therefore, there is an urgent need for a lithium battery protection board to pr...
