Problems solved by technology

[0004] The present invention aims to overcome the problem that lithium batteries in the prior art are prone to spontaneous combustion, and provides a device for preventing spontaneous combustion of lithium batteries. In the case of spontaneous combustion of lithium batteries, the explosion-proof parts are activated to extinguish the fire, ensuring the safety of lithium batteries during use. At the same time, the lithium battery self-ignition device is made of more common materials, which reduces production costs and is easy to put into a wide range of production and applications

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as figure 1 The shown device for preventing spontaneous combustion of a lithium battery includes a lithium battery pack, a cage 1 and an explosion-proof component 2. A number of battery installation slots 11 are evenly arranged on the cage 1, and both ends of the lithium battery 3 are inserted into the battery installation slots. 11, the lithium battery 3 is fixed by using the battery installation groove 11. The installation distances between the lithium batteries 3 and the lithium batteries 3 are the same. According to different practical conditions and the demand for the number of lithium batteries 3 required, the size of the cage 1 can be changed so as to change the number of installed lithium batteries 3 . The explosion-proof part 2 is inserted on the cage 1, and the explosion-proof part 2 is inserted in the gap formed by four...

Abstract

The invention discloses a device for preventing spontaneous combustion of lithium batteries, which is applied to a lithium battery pack and structurally comprises retainers arranged at two ends of thelithium batteries of the lithium battery pack, explosion-proof parts are inserted into the retainers, the explosion-proof parts are inserted among the lithium batteries of the lithium battery pack ina staggered manner, and flame retardants are arranged in the explosion-proof parts. The explosion-proof part is adopted, when the temperature of the lithium battery reaches a certain limit, namely combustion, fire is actively extinguished, and the safety of the lithium battery pack in the using process is ensured.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to a device for preventing spontaneous combustion of lithium batteries. Background technique [0002] Lithium battery is a primary battery. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of microelectronics technology, miniaturized equipment tends to increase, and the requirements for power supply also increase. Large-scale practical stage within the lithium battery machine. However, during the use of lithium batteries, due to various reasons such as circuit short circuit, overcharge, overheating, overvoltage, impact, etc., the battery will fail, which may easily cause the battery to heat up, catch fire, or even explode. Once a battery cell goes into thermal runaway, it generates enough heat that the adjacent battery cells also go into thermal runaway. As...
