Abstract

Zr4+ doped carbon coated LiFePO4 cathode [C-LiZrxFe1-xPO4 (where x=0.02)] material were synthesized by a one pot solid-state synthetic route for its use in rechargeable lithium-ion battery. The carbon coating over the phosphate material was done using a natural precursor, camphor. The calcinations and sintering temperatures were set at 450ºC and 700ºC, respectively, which were selected from the TGA-DTA experiment. The synthesized materials were characterized by various spectroscopic techniques, such as; FTIR, Powdered XRD and SEM. Electrochemical studies of the synthesized materials were carried out by cyclic voltametry and charge-discharge behavior after preparing a laboratory model cell against lithium anode. It was found that C-LiZrxFe1-xPO4 (where x=0.02) material coated with carbon from a natural precursor (camphor) shows better discharge capacity of 159 mAhg-1 during the first few cycles compare to that of pure LiFePO4.
