In this study, LiMn0.7Fe0.3PO4/C composite materials have been synthesized from a low-cost Fe2O3 and Mn3O4 precursor via a two-step solid-state reaction by spray drying process. The as-prepared LiMn0.7Fe0.3PO4/C provides enhanced discharge capacity and low-temperature performance compared to LiMn0.7Fe0.3PO4/C synthesized by a one-step solid-state method with the same precursors. Thus, the method to be described herein is a promising option in the search to reduce the cost of large-scale synthesis of LiMn0.7Fe0.3PO4/C for use in lithium-ion batteries, while maintaining adequate electrochemical performance.
