Abstract:
A process of preparing mesoporous nano-composite LiMn1-xFexPO4 (0≦x≦1, e.g., x=0, 0.2, 0.5 and 0.8) particles. The process contains the steps of providing a mixture of a soft-template compound, a lithium ion-containing compound, an iron ion-containing compound, a manganese ion-containing compound, and a phosphate ion-containing compound in a solvent, removing the solvent to obtain a LiMn1-xFexPO4 precursor, and calcining the precursor followed by milling and annealing. Also disclosed is a mesoporous nano-composite LiMn1-xFexPO4 particle prepared by this process.
