Storage-control integrated lithium battery with fireproof protection function and electric vehicle

Abstract

The invention provides a storage-control integrated lithium battery with a fireproof protection function and an electric vehicle. The storage-control integrated lithium battery comprises a shell, a spacer layer, a liquid containing box and a temperature sensor, wherein a mounting plate is mounted in the shell, and a battery is mounted above the mounting plate; the spacer layer is wrapped outside the shell; the liquid containing box is arranged on the spacer layer; the temperature sensor is arranged on the inner wall of the spacer layer; the liquid containing box communicates with the spacer layer through a pipeline, and an electromagnetic valve is arranged on the pipeline; and the liquid containing box is used for containing high-temperature-resistant liquid, and when the temperature sensor exceeds a set threshold value, the high-temperature-resistant liquid in the liquid containing box is injected into the spacer layer through a pipeline to provide fireproof protection for the shell. The technical problem of how to improve the safety and fire prevention of the storage-control integrated lithium battery is solved, and when a fire or a dangerous situation occurs around, the high-temperature-resistant liquid is injected into the spacer layer to effectively protect the stability of the internal structure of the lithium battery, so that the explosion accident of the lithium battery is avoided.

Problems solved by technology

[0003] Lithium batteries, promising lithium metal batteries, generally use manganese dioxide as the positive electrode material, metal lithium or its alloy metal as the negative electrode material, and use non-aqueous electrolyte solution. Due to the large capacity of lithium batteries, the charge and discharge are stable, and should be widely used in Among all kinds of electrical equipment, the use of electric vehicles is particularly obvious. However, the theft of electric vehicle batteries is particularly obvious, which brings troubles to the travel of users and damages the interests of users.

[0004] Most of the existing lithium metal batteries do not have the function of fire prevention. Once a fire occurs in the surrounding area, the lithium metal batteries are likely to be affected and burnt, thus causing personal safety hazards. How to provide lithium metal batteries with safety protection measures is a challenge. It is a difficult problem to be solved to provide the necessary protection in case of emergencies
