Cylindrical Lithium Battery

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

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.

Quick Q&A: How does airtightness testing really work? How to define airtightness testing standards

This article introduces the principle of airtightness testing, steps, standard definitions and methods to ensure stable and reliable results. Airtightness testing is through the application of positive or negative pressure to monitor the pressure change to determine the sealing performance, divided into positive pressure method, negative pressure method and other ways, the process includes product positioning, inflation, pressure stabilization, testing and judgment. The development of standards requires comprehensive consideration of various factors. Precision Engineering can provide standardized and customized services for different enterprises, from experimental verification, jig design to mass production line data system integration.

Power Battery

Why choose Precision Engineering for new energy battery pressure resistance and air tightness testing? Four advantages of one article to understand

This paper introduces the lithium battery pressure resistance and gas tightness test, which aims to guarantee the sealing and structural strength of the battery to prevent the risk of leakage of liquid and gas, and is a key link in safety, regulations and quality control. The test methods mentioned in the article include direct pressure method, helium test method and pull burst water test method. Precision Industrial Technology has technical advantages in this field, providing testing solutions for many enterprises and helping domestic testing equipment to replace imports.
