In this collaboration, the large cylindrical battery helium inspection equipment provided by our company undertakes the final and crucial sealingity leak detection process before the batteries are manufactured. The complete leak detection solution provided by our company comprehensively covers the key steps such as the first helium inspection, the second helium inspection, and the electrolyte leakage detection. Guangshun is the only and exclusive equipment manufacturer in China that has successfully developed this complete solution and applied it on a large scale to the production lines of major customers including Duofu. With its outstanding performance, this equipment achieves precise detection at multiple levels of 65 ppm, 85 ppm, and 150 ppm for large cylindrical battery power cells, like a loyal "security guard", building the final solid defense line for the safety and reliability of cylindrical battery power cells.
