Battery Applications
Electrochemistry
Electrochemical battery applications provide insight into battery performance and materials characterization.
Electrochemical techniques can help with:
- Voltage characteristics upon charge and discharge
- Cycling performance and calculating coulombic efficiency
- Battery capacity and power
- Determining state of charge, depth of discharge, and state of health
- Internal resistance
- Life cycle evaluation
- Electrolyte resistance and charge transfer resistance
- And more!
Electrochemical Impedance Spectroscopy (EIS)
Basic Materials
Karl Fischer Titration
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
Ion Chromatography provides solutions for anion and cation determination in battery components and materials.
Ion Chromatography
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.
