Doping Effects of LiFePO4 Cathode Materials for Lithium-Ion Batteries

The effects of doping on Fe site of LiFePO4 cathode materials with varying concentrations of W, synthesized by the solution and ball milling methods, will be presented. X-ray diffraction, cyclic voltammetry, and constant current charge/discharge measurements are employed to characterize the structural, electronic, and electro chemical properties of the samples. The effects of varying reaction temperature and environmental composition will also be analyzed.
