High rate performance Fe doped lithium zinc titanate anode material synthesized by one-pot co-precipitation for lithium ion battery

Fe doped lithium zinc titanate anode material has been synthesized via one-pot co-precipitation method for the first time. It is found that Fe element can enhance the electrochemical property of lithium zinc titanate obviously. Li2ZnFe0.05Ti2.95O8 particle shows largest specific capacity and best cyclic performance at high current densities among other particles. The introduction of Fe element improved electrochemical performance of the Li2ZnTi3O8 should be owing to the enhancement of the electric conductivity and lithium ion diffusivity of Li2ZnTi3O8.
