Lithium rechargeable batteries have become the main power source for electronics due to high energy and long battery life.  The use of these batteries is not only applicable to computers, but for powering vehicles, cutting down on the emissions of CO2.  Lithium ion batteries offer the largest energy density and output of all known rechargeable batteries. However, transition metal oxides, commonly used as cathode materials, in these batteries are wrought with safety concerns, poor rate capacity and capacity degradation over a long period of time. Hence the current lithium batteries cannot be used in vehicles.  This study uses metal phosphates to synthesize carbon-coated LiMPO4(M=Co,Mn,Ni) nano-particles (NPs).  These new lithium materials are expected to have high electric and ionic conductivity, coulomb efficiency, rate capability, capacity retention and cycle life. The LiMPO4 NPs were synthesized and characterized using x-ray diffraction, atomic force microscopy, Raman spectroscopy, and the scanning electron microscope.
