abstract: here, we develop a novel strategy for the fabrication of li4ti5o12/carbon core−shell electrodes using metal oxyacetyl acetonate as titania and single-source carbon. importantly, this novel approach is simple and general, with which we have successfully produce nanosized particles of an olivine-type limpo4 (m = fe, mn, and co) core with a uniform carbon shell, one of the leading cathode materials for lithium-ion batteries. metal acetylacetonates first decompose with carbon coating the particles, which is followed by a solid state reaction in the limited reaction area inside the carbon shell to produce the lto/c (lmpo4/c) core−shell nanostructure. the optimum design of the core−shell nanostructures permits fast kinetics for both transported li+ ions and electrons, enabling high-power performance.![]()
