Reasons why lithium batteries need leak detection:
A general lithium-ion battery cell is composed of a positive electrode, a negative electrode, a separator, and an electrolyte. These cells are arranged in a package. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements.
Lithium batteries mainly require leak detection at the welding part of the shell . If the electrolyte in the lithium battery leaks out due to the leakiness of the shell, it may react violently with the humid environment, which will not only cause serious harm to the environment and personnel, but also affect the service life of the equipment. ,.
Therefore, in the important links of assembly and sealing of lithium batteries (cylindrical and prismatic units are welded), leak detection must be done and manufactured according to the production process.

Through the main process of constant pressure intake and balancing, the leakage value is obtained by the sensor and system in the valve body sealing test equipment through a series of sampling, calculation and analysis.
This equipment is an ammonia detector after the power battery injection hole is sealed, which mainly includes battery code scanning, loading, leakage detection, evacuation, nitrogen filling, ammonia detection, and other processes.
