Q&A: How to do hermeticity test and burst test for cylindrical lithium batteries? A clear article

2025-11-20

This article introduces the two core tests of cylindrical lithium battery: air tightness test and burst test. The airtightness test accurately detects whether the battery seal is leaking through minimally invasive drilling, professional fixture system, pressure application and monitoring, etc. The burst test monitors the pressure resistance limit and rupture mode of the shell by slowly and uniformly increasing the pressure. With the advantages of integrated airtightness + bursting, one machine with multiple molds, high pressure capability, and accurate and stable results, Precision Tech's solution is suitable for the R&D and mass production of automotive-grade and power storage batteries.
