- Basic Materials
- Galvanostatic charge-discharge of Li-ion battery
Titration provides a reliable and accurate moisture analysis solution for batteries and battery components.
Karl Fischer Titration
Lithium-ion batteries must be completely free of water (concentration of H2O <20 ppm), because water reacts with the conducting salt, e.g. LiPF6, to form hydrofluoric acid. Titration allows for reliable moisture analysis in raw materials, electrode coatings, separator foils, and electrolytes.

Ion Chromatography provides solutions for anion and cation determination in battery components and materials.
To optimize battery performance and safety, lithium, fluoride and hexafluorophosphate content in electrolytes or in eluates of different components should be evaluated. Various inorganic and organic anions and cations can be determined by ion chromatography over a wide concentration range.
