ELT Vmax
Electrolyte Leak Detector for Inline leak testing during mass production of battery cells
Patented direct electrolyte leak test method developed by INFICON
With this unique method for detecting electrolyte leaks, the ELT Vmax enables fast and efficient leak testing in a wide range of industries.
Whether in the automotive industry, communications technology, consumer electronics, power tools, or medical technology, the ELT Vmax reliably detects electrolyte leaks down to the micrometer range—finding leaks up to 1,000 times smaller than with conventional methods.
Faster and more accurate measurement of metal-ion batteries in mass production
The ELT Vmax was developed specifically for the requirements of mass production of any metal-ion battery. With its ability to measure even faster and more accurately, it is ideal for leak testing in highly automated and efficient mass production. By optimizing measurement speed and accuracy, the ELT Vmax helps to make production processes more reliable and productive.
Testing of solid-state batteries
The ELT Vmax is also suitable for newer battery technologies. Thanks to its high sensitivity, the ELT Vmax is able to detect even the smallest amounts of electrolyte. This enables reliable and replicable testing of solid-state batteries, which require higher sensitivity.
Module and Power Pack testing
The sensitivity of the ELT Vmax makes it possible to test larger volumes efficiently. This opens up new possibilities for testing battery modules in mass production.
Easy integration of leak testing into your battery cell production cycle
Thanks to intelligent process control, a powerful mass spectrometer system, and a multi-chamber connection that can be combined with powerful external pumps, the ELT Vmax enables the fastest cycle times. With its modular and compact design, which is reduced to the essentials, the ELT Vmax offers system integrators a space-saving AND integrable solution for high-speed production systems.
Advantages at a glance
