TiO2(B)/Anatase Composites Synthesized by Spray Drying as High Performance Negative Electrode Material in Li‐Ion Batteries

The power of spray-dried TiO2 in LIBs: TiO2(B)/anatase is synthesized by spray drying and investigated as negative electrode material in Li-ion batteries. It exhibits excellent Li-ion storage performances, especially at high charge/discharge rates. The presence of the β phase of TiO2 improves Li-ion diffusivity. Additionally, the scalable synthesis method also allows for Nb-doping, which assists in the maintenance of the electronic conductivity as the thickness of film increases.
