Abstract
Objects of the present invention include creating cathode materials that have high energy density and are cost-effective, environmentally benign, and are able to be charged and discharged at high rates for a large number of cycles over a period of years. One embodiment is a battery material comprised of a doped nanocomposite. The doped nanocomposite may be comprised of Li—Co—PO4; C; and at least one X, where said X is a metal for substituting or doping into LiCoPO4. In certain embodiments, the doped nanocomposite may be LiCoMnPO4/C. Another embodiment of the present invention is a method of creating a battery material comprising the steps of high energy ball milling particles to create complex particles, and sintering said complex particles to create a nanocomposite. The high energy ball milling may dope and composite the particles to create the complex particles.
