// Development of new active materials

Detailed information about our services in regard to materials research is presented in the topics. For development projects, we are equipped with comprehensive laboratory facilities and an experienced team of more than 45 scientist and technicians.



Range of services

  • Development of new active materials: high-voltage spinels, lithium transition metal phosphates and silicates, titanates, alloy anodes and electrolytes including additives
  • Optimisation of "classic" active materials: morphology, surface modification etc.
  • Analysis of the interactions between the electrode/electrolyte and anode/cathode
  • Electrochemical measurement in full cells using reference electrodes
  • Investigating the ageing effects of battery materials and components using standard chemical analysis methods, surface area analysis, deep profile analysis at a high resolution as well as thermoanalytic methods such as TG/DSC-MS and ARC
  • In-situ investigations of materials in model cells
  • Ex-situ investigations of materials from real cells
  • Electrochemical characterisation of materials: galvanostatic cycle test, cyclic voltammetry and impedance spectroscopy
  • Electroanalytic investigations of materials, e.g. on the basis of voltametric methods and rotating (ring) disk electrodes


    • Synthesis laboratory for producing inorganic powders up to the kilogram scale
    • Physical-chemical methods for material characterisation:
      element analysis, scanning electron microscopy, structure analysis, thermal analysis, determination of flash point, determination of steam pressure, measurement of electrical conductivity
    • Electrochemical test benches for material and component characterisation
    • Electrochemical in-situ methods:
      FTIR spectroscopy, Raman spectroscopy, dilatometry and gassing, etc.
