Abstract

Carbon-coated LiFeBO3 composite material was prepared by a rheological phase reaction method and successive annealing procedure. In the synthesis procedure, citric acid was selected as carbon source. The structures and morphologies of LiFeBO3 and carbon-coated LiFeBO3 samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. The effect of carbon coating and the annealing temperature on the structure and electrochemical properties have also been investigated. The electrochemical tests showed that the carbon-coated LiFeBO3 could greatly improve the discharge capacity, rate capability and cycling stability due to the improved electric conductivity. The carbon-coated sample (LiFeBO3/C) shows good electrochemical performance (the initial discharge capacity of 139.7 mAh g-1 at 5 mA/g). These results indicate that the carbon-coated LiFeBO3 could be a promising cathode material for lithium ion batteries.
