Niobium Precursors for Battery Applications（TANIOBIS）
Application Example
- Coating materials, e.g. for niobium based coating of cathodes for solid state batteries
- Doping of cathode active materials and solid electrolytes
- Mixed oxide anode materials:
- Niobium titanium oxide
- Niobium tungsten oxide
Portfolio and Advantages

Niobium Ethoxide
- Suitable for solvent-based coating solutions
- Co-solution with other ethoxides (i.e. Li-ethoxide) possible
- Forms very thin layers of amorphous Nb2O5 / LiNbO3 after drying/hydrolysis;
- Well-established for Cathode Active Material-coatings for all solid state Li Ion Batteries (LIB)
