摘要: Thin layers of densely packed idiomorphic Li4Ti5O12 crystals were prepared directly on a Pt substrate by using LiCl–NaCl mixed flux. The thin film colloidal anatase nanoparticles with an ∼30 nm diameter was fully converted into 100–200 having polyhedral shapes well-defined {111} faces during the evaporation-driven flux growth. Cross-sectional structure analysis revealed that interface between and seemed to be atomically bonded. Galvanometric charge discharge properties strongly supported our consideration formation. crystal layer exhibited large capacity close its theoretical value under 0.1C rate no assistance from additional electroconductive materials binders, meaning interfaces provide seamless transportation pathways. We also addressed formation mechanism accompanied experimental results in situ X-ray diffraction, t...
