- Abstract
- LiFePO4 nanoparticles were grown on nano-graphite platelet (NGP) using a simple chemical route. The material was used as the cathode in Li-ion rechargeable batteries and exhibited excellent cyclability and rate capability because of the easy electron transport in it. The electrochemical stability of the electrode was improved by the two-dimensional conductive network of the NGP. The resulting electrodes delivered a specific capacity of about 150 mA h g(-1) at a current rate of 135 mA g(-1) (similar to 0.8 C) after 100 cycles with no capacity fade. At elevated current rates, the electrodes exhibited capacities of more than 100 mA h g(-1) a current density of 2000 mA g(-1) (similar to 12 C) without further incorporation of conductivity agents or coatings.
