Abstract

A new and effective method to prepare TiO₂/C core-shell nanocomposites as active anode materials for lithium ion batteries with markedly ameliorated electrochemical performance is described. Initially a precursor, polyacrylonitrile coated nano-TiO₂ particles, is formed by emulsion polymerization. This precursor is heat-treated under argon atmosphere to achieve the nanocomposite. The conductive carbon shell enveloped TiO₂ nanoparticles and suppressed the aggregation of the core nanoparticles during cycling. In addition it is attached closely to the nano-cores, and the kinetics of lithium intercalation and de-intercalation, the apparent diffusion coefficient of lithium ions and the consequent cycling behavior are significantly enhanced. This provides a good way to improve cycling and kinetics of nano-anode materials.
