LiFePO4-Li3V2(PO4)3 nanocomposite cathode with a high energy density using one-pot Combustion synthesis |
| 초록 |
Highly crystalline carbon-coated 0.66LiFePO4•0.33Li3V2(PO4)3(LFP-LVP) nanocomposite was synthesized by a one-pot combustion strategy by a polyol medium at low temperature. In this study, electron microscopy delivered the as-synthesized composite consisting of spherical particles which have average diameters in the range of 30–60nm. Following calcination, a crystal growth phenomenon and particle aggregation were observed at 800 °C, thus resulting in an increase in the average particle size to 200– 300 nm. Testing for a lithium-ion battery, the nanocomposite electrode provided good electrochemical properties with higher operating potentials hence enhanced energy density and excellent rate capacity. Corresponding to an energy density of 46.88 Wh Kg−1 at 6.4 C, the composite cathode showed a high reversible capacity of 156 mAh g−1 at 0.1 C and exhibited a remarkable reversible capacity of 119 mAh g−1. |
