Robust and Sensitive Measurement of Trace Element Impurities

An industrial analysis

Lithium ion (Li-ion) batteries are increasingly being used in electronic devices and electric vehicles. The demand for electric vehicles is expected to grow significantly in the next years, as they can be a viable alternative to fossil fuel-driven vehicles and help to rapidly decrease CO2 emission from traffic.

For production, especially in the ramp-up phase, regular and rigorous quality control of all components, including the lithium salt, anode and cathode material, and electrolyte, of an Li-ion battery is crucial. The electrolyte plays an important role in the charging and discharging performance of the battery, and hence needs to be checked for potential impurities. At the same time, the electrolyte is also a sample type that allows the investigation of aging processes, as degradation products from all components of the battery can accumulate within it over time.
