Precise down to micrometer, highly sensitive and significantly faster

From powering electric and fuel cell vehicles to powering mobile communication devices, power tools and medical equipment, metal-ion batteries, like lithium-ion, sodium-ion or even aluminium-ion batteries, are essential to our everyday lives. That's why it's just as important to prevent metal-ion battery leakage as it is to prevent moisture ingress from any leaks to ensure safety, longevity and reliability.  


Detecting lithium-ion battery leaks down the micrometer range

With the ELT3000 PLUS Battery Electrolyte Leak Detector, INFICON offers a unique, non-destructive leak testing solution for all metal-ion battery cells, including fragile pouch cells. It is the only system that detects electrolyte leakage directly, rather than through indirect parameters (like pressure changes). Based on mass spectrometer technology, it can find leaks down to the micrometer range, up to 1,000 times smaller than the ones found with traditional pressure test methods.    


Automating the process for high throughput end-of-line testing

The modular design and modern field bus interfaces make it easy to integrate the ELT3000 PLUS into your automated processes. Short cycle times, customized test chambers and optional batch testing of several battery cells at a time ensure high throughput end-of-line testing. Testing results are recorded for full traceability and can be handed over to a QM system automatically.   

Advantages at a glance

  • High-speed throughput due to short measurement times and simultaneous testing
  • Integration capability in automated production lines due to a large selection of interfaces
  • Quality through innovative end-of-line testing
  • High operational readiness due to integrated gross leak detection:  ELT3000 PLUS is protected from severe contaminations
  • Universally capable
  • Inline mode for easy integration into automated processes
  • Stand-alone mode for manual operation, such as in battery development or pilot projects
  • Standard, customized chamber for manual operation
  • Intuitive operation, no time-consuming training required
