| abstract |
The present invention relates to metal oxides containing multiple dopants. The metal oxides have the formula:wherein M is a transition metal,wherein Bi is an element used to replace the transition metal M and wi is the fractional amount of element Bi in the total dopant combination such thatn is the total number of dopant elements used and is a positive integer of two or more, wherein the fractional amount wi of dopant element Bi is determined by the relationshipEi is the oxidation state of dopant Bi in the final product LiMy-x[A]xOz or My-x[A]xOz, the dopant elements Bi are cations in the intercalation compound, and the ratio of Li to O in the intercalation compound is not smaller than the ratio of Li to O in the undoped compound LiMyOz or MyOz. The present invention also includes methods of preparing same and specific embodiments of same. |
