Abstract

The surface of rod-like LiFePO ₄ modified with a conductive nitrogen-doped carbon layer has been prepared using hydrothermal processing followed by post-annealing in the presence of an ionic liquid. The conductive surface modified rod-like LiFePO ₄ exhibits good capacity retention and high rate capability as the nitrogen-doped carbon layer improves conductivity and prevents aggregation of the rods during cycling.
