Electrode development

We develop cost-efficient processes for electrode fabrication basing on aqueous or completely solvent-free processes.

  • material evaluation and feasibility studies
  • process development for continuous electrode fabrication
  • system development for dry electrode fabrication


Functional films for cell components

We develop thin functional films to improve cell safety and stability

  • inorganic heat resistant layers on separators and electrodes
  • ion-selective separator films
  • primer coatings


High-energy anodes (Li-metal- and Si-anodes)

IWS-developed processes for anode fabrication basing on lithium or silicon allow increasing the energy densities of Li cells.

  • optimization of energy density
  • 5-50 µm thick films
  • tailored microstructure
  • interfaces and protective films
