Abstract

A phase separated carbon and Fe0.5Ti2(PO4)3 bi-layer was fabricated on the surface of TiP2O7 particles. As the carbon layer improves electronic conductivity, and the Fe0.5Ti2(PO4)3 layer favors the transference of lithium ions, the capacity and rate performance of the TiP2O7 anode material for aqueous lithium rechargeable batteries are greatly enhanced.
