Metal oxide containing multiple dopants and method of preparing same

摘要

The present invention relates to metal oxides containing multiple dopants. The metal oxides have the formula: LiMy-x[A]xOz or My-x[A]xOz, wherein M is a transition metal, 0 1 $\sum _{i=1}^{n}it{w}_{i}it{B}_i$ 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 that 2 $\sum _{i=1}^{n}it{w}_i=1,$ n 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 relationship 3 $\sum _{i=1}^{n}it{w}_{i}it{E}_i=\mathrm{the}itit\mathrm{oxidation}itit\mathrm{state}itit\mathrm{of}itit\mathrm{the}itit\mathrm{transition}itit\mathrm{metal}ititM\pm 0.5,$
