The invention provides a lithium battery safety box. The lithium battery safety box comprises a battery pack, conducting wires, an airbag, a temperature sensor, a box body, a cover and electrode tips. The temperature sensor is connected with the battery pack through one conducting wire, the airbag is internally provided with a compressed flame-retardant gas, and the airbag is provided with a solenoid valve; the temperature sensor is connected with the solenoid valve, and the cover is used for installation on the box body to form an enclosed space, and the battery pack, the airbag, the temperature sensor and the solenoid valve are sealed inside the box body; the cover is provided with through holes and copper sheets, and the copper sheets are installed at the inner side of the cover and extend from the edge to the middle; each electrode tip comprises a conductive column and an insulation base, and the conductive columns penetrate the insulation bases and are fixedly connected with the insulation bases; the electrode tips are inserted into the through holes and are fixedly connected with the cover through friction forces; the bottom portions of the conductive columns are in contact with the copper sheets; and the copper sheets and the battery pack are connected through the conducting wires. According to the invention, flame retardation and automatic power failure of a lithium battery are realized, damage caused by combustion of the lithium battery is avoided, and the application safety of the lithium battery is improved.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a lithium battery safety box. Background technique [0002] Since the lithium battery is made of flammable organic electrolyte solution and active metal lithium, the energy density of the battery is high, and there are certain deficiencies in safety. When the battery is working, due to energy conversion, part of the energy will escape in the form of heat, which will cause the battery to heat up. If it is under improper use conditions such as thermal shock, overcharge, overdischarge, and short circuit, the active material and electrolyte components inside the battery will react and generate a large amount of heat in a short period of time, which will lead to The battery burned and exploded, causing a safety accident. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a lithium battery safety box. [0004...
