Preparation of LiFePO4 as a Cathode Material for Lithium Ion Batteries by a Citric Acid Complex Method
LiFePO4 powders were prepared by a citric acid complex method. The effects of source composition and firing conditions on the formation of LiFePO4 were investigated. Single phase and well-crystallized LiFePO4 powders were obtained at 500°C for 5h. The particle size of the obtained powder is smaller than that of powder prepared by the conventional solid-state reaction method.
