6 FAQs about [Lithium battery helium inspection technical parameters]
How do you test a lithium ion battery?
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.
Are there reliable leak-detection standards for helium battery cells?
“There currently are no reliable tests on which to base leak-detection standards for a full range of soft-pouch, cylindrical or prismatic battery cells in use throughout the industry,” says Daniel Wetzig, head of leak-detection R&D at INFICON—a specialist in gas analysis technology that designs and produces helium leak testing equipment.
Why do we need industry standards for testing lithium-ion battery cells?
Implementing industry standards for testing lithium-ion battery cells is needed for a variety of reasons: Leaking battery cells can dramatically shorten battery life, increase warranty costs, affect customer satisfaction and damage product reputation, as well as create safety-and-drivability problems.
Can helium leak test be used for pouch cells?
Furthermore, the helium leak test cannot be used for pouch cells. There currently are no reliable tests on which to base leak-detection standards for a full range of soft-pouch, cylindrical or prismatic battery cells in use throughout the industry.
What is the helium tracer-gas leak-rate test limit for lithium-ion battery cells?
A helium tracer-gas leak-rate test limit of 10-6 mbar∙l/s would apply for all three types of lithium-ion battery cells. While leak-rate test limits are the same for all three battery cell types, pouch-cell testing presents a unique challenge.
Do helium tests detect leaks?
The problem with this method is that, while helium tests can detect many common leaks in the casing, the test is performed before the cell is fully assembled. The cell can only be filled with electrolyte and sealed after the test is complete, so the sealed fill port is not tested for leaks.
