APPROACH FOR MANUFACTURING EFFICIENT MESOPOROUS NANO-COMPOSITE POSITIVE ELECTRODE LiMn1-XFeXPO4 MATERIALS

摘要

A mesoporous nano-composite LiMn_1-xFe_xPO₄ (0≦x≦1) particle that has a uniform carbon coating on the surface of the particle. Also disclosed is a mesoporous nano-composite LiMn_1-xFe_xPO₄particle prepared by a process including steps: (i) 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; (2) removing the solvent to obtain a LiMn_1-xFe_xPO₄ precursor; and (3) calcining the precursor followed by milling and annealing to obtain the LiMn_1-xFe_xPO₄particle.
