TDTO (Three-Dimensional Titanium Oxide)
Through the present invention a new three- dimensional (3D) TiO2/C architecture can be provided.In this architecture, the primary TiO2 nanoparticles are wrapped with carbon, forming spherical secondary particles, and the spherical Ti02/C Secondary particles further agglomerates with each other into a plate- like morphology.
Improved electrochemical Performance
Improved electronic conductivity
Homogeneous carbon Coating
Higher energy density of super capacitors
the construction of a three- dimensional TiO2 nanostructure, and a more homogeneous carbon coating lead to an improved performance. With the present invention, the energy density of rechargeable batteries (both lithium ion batteries and sodium ion batteries) and the power density of supercapacitors can be improved by the design of this architecture.
Common strategies of the carbon coating always lead to serious phase separation or agglomeration of the TiO2 nanoparticles, and a rather inhomogeneous distribution of the carbon coating, which results in relatively poor electronic conductivity and poor electrochemical performance. In addition to that, the construction of a three- dimensional TiO2 nanostructure, and a more homogeneous carbon coating lead to an improved performance. With the present invention, the energy density of rechargeable batteries (both lithium ion batteries and sodium ion batteries) and the power density of supercapacitors can be improved by the design of this architecture.
