Polyanion-type cathode materials for lithium ion batteries have attracted much attention recently in view of their stable structures. Here, relatively rarely investigated LiFeTiO₄ and its composite with carbon nanotubes (CNTs) have been synthesized via solid-state reactions. Their structures, chemical compositions and morphologies are characterized using various techniques. As a cathode material, LiFeTiO₄/CNTs can deliver a highest first discharge capacity of 465.7 mA h g⁻¹ and there is still 202.4 mA h g⁻¹ remaining after 100 cycles at 0.1C. The rate capabilities of LiFeTiO₄/CNTs are also studied. The promising electrochemical performance of LiFeTiO₄/CNTs is well analyzed and discussed.
