Nitridation effect on lithium iron phosphate cathode for rechargeable batteries

A novel oxynitride Li 0.94 FePO 3.84 N 0.16 with olivine structure (space group Pnma , no. 62) has been synthesized by heating a parent LiFePO 4 precursor obtained by citrate chemistry in flowing ammonia at 650 °C. The polycrystalline sample has been characterized by X-ray and neutron powder diffrac...
