The power of spray‐dried TiO 2 in LIBs : TiO 2 (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 TiO 2 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.
