This article will give you an in-depth understanding of what lithium battery helium detection is and the important role it plays in solving helium leakage problems.
Common lithium‐ion battery types. Testing for leak tightness requires some form of leak detection. Although various leak detection methods are available, helium mass spectrometer leak detection (HMSLD) is the preferred and is being used broadly to ensure low air and water permeation rates in cells.

The most common method used with parts that are pressurized is to scan them with a sniffer probe attached to the inlet of the leak detector, paying special attention to areas prone to leaks such as welds, seams, seals, or feedthroughs. When a leak is encountered, helium is captured through the probe and detected by the sensor.
HMSLD is a clean, dry test method. It provides 100‐times greater sensitivity, can be used to locate and measure leaks, and is not compromised by temperature fluctuations. Agilent leak detectors may be used in any of several ways to find or measure leaks. When a leak is encountered, helium is captured through the probe and detected by the sensor.
INFICON is bringing its technology and leak detection know-how to the battery market with the ELT3000 Battery Leak Detector. The ELT3000 was developed for integrity testing of lithium-ion battery cells, such as those used in mobile devices.
Agilent leak detectors may be used in any of several ways to find or measure leaks. When a leak is encountered, helium is captured through the probe and detected by the sensor. Leak sites are identified quickly thanks to fast response time. In this configuration, a cumulative leak rate can be determined quickly and accurately.
