The search for alternative cathode materials for Li-ion batteries has recently emerged Li2FeP2O7 pyrophosphate as a new potential competitor for LiFePO4 material. It has a possibility to offer good rate capability, lithium ion diffusivity and volumetric energy density, and is a material of high safety and low raw materials cost. In addition, there is the probability of releasing the second Li-atom at a higher redox potential of 5.2 V, where the theoretical capacity would reach 220 mAhg−1. Optimized solid state reaction is used for the synthesis of pure Li2FeP2O7 powder and a composite Li2FeP2O7/C. The synthesized powders are characterized by X-ray powder diffraction, field emission scanning electron microscopy, FTIR spectroscopy, and galvanostatic charge/discharge cycling.
