Abstract

LiCoPO 4/C nanocomposite with growth controlled by carbonate anions was synthesized via a unique solid-state fusion method. Carbonate anions in the form of H 2CO 3 or a mixture of H 2CO 3 + (NH 4) 2CO 3 have been used as a growth inhibiting modifier to produce morphology controlled lithium cobalt phosphate. The presence of cobalt phosphide (Co 2P) as a second phase improved the conductivity and electrochemical properties of the parent LiCoPO 4. The formation of Co 2P is found to be achievable only in an inert atmosphere. Super P ® carbon (10 wt.%) provided an adherent carbon coating on pristine LiCoPO 4 resulting in the LiCoPO 4/C composite cathode. This electrode exhibited enhanced electrochemical properties: capacity of 123 mAh g -1 with excellent capacity retention of 89% after 30 cycles, and reasonable rate capability of up to 5 C rate. The synergistic effect of carbonate anions and formation of Co 2P under inert atmosphere has influenced the electrochemical behavior of LiCoPO 4/C cathode through controlling the morphology and increasing the conductivity.
