There have been significant improvements in the Lithium-ion battery technology versus alternatives such as NiCd (Nickel-Cadmium) or NiMH (Nickel-Metal Hydride) cells since Lithium-ion provides higher voltages and larger power densities.Inspired by biology, which uses careful control of local solution chemistry as well as organics, we have developed novel solution methods to produce nanostructured LiFePO4 (LFP) cathodes.By utilizing a solvothermal method, modification of solvent and pH promotes the formation of LFP nanostructures with controlled size, monodispersity, and morphology.Crystal phase and growth behavior were monitored by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), while particle morphologies were investigated by Scanning and Transmission Electron Microscopy.
