Can helium mass spectrometer leak detector be applied to secondary helium detection of new energy batteries?

There are many production processes for battery assembly, including winding, hot pressing, X-RAY testing, pole ear welding, cover plate welding, core coating, top cover welding, ammonia testing, vacuum baking, liquid injection, high-temperature storage, chemical transformation, secondary liquid injection, sealing, volume separation, secondary re inspection, constant temperature standing, OCV testing, coating, sorting and assembly, and module assembly.

The two helium testing processes directly determine the safety performance of the battery, and leak detection is an essential step in ensuring battery safety.

Therefore, improving the accuracy and efficiency of lithium battery leakage detection is crucial. The commonly used primary and secondary helium testing schemes in the industry.

The first chlorine test completed the first leak detection, and the second ammonia test conducted another leak detection to eliminate some NG products killed by the first nitrogen leak detection.

Currently, major battery companies are actively improving their manufacturing processes and upgrading their production lines to enhance product quality from the manufacturing level.

From the perspective of improving product quality, battery factories will increasingly attach importance to helium testing, and also put forward higher requirements for helium testing equipment enterprises.

So the above is an introduction to the application of helium mass spectrometer leak detectors in secondary helium detection of new energy batteries. If you have a need for helium mass spectrometer leak detectors, please consult the customer service of EVP official website~
