[0002] With the continuous advancement of science and technology, lithium battery technology has become mainstream. Lithium batteries are a type of battery that uses lithium metal or lithium alloys as the positive and negative electrode materials and a non-aqueous electrolyte solution. Lithium batteries are generally divided into lithium metal batteries and lithium-ion batteries. Due to the highly active chemical properties of lithium, the processing, storage, and use of lithium batteries have very high environmental requirements.

[0003] Lithium batteries need to be tested before they are put into use. During the test, the lithium battery may overheat or break and emit harmful gases. If these harmful gases are directly released into the air, they will pollute the ambient air and cause harm to the physical and mental health of the workers. Utility Model Content

[0016] Compared with the prior art, the present invention has the following beneficial effects:
