COATED LITHIUM-RICH LAYERED OXIDES AND PREPARATION THEREOF

摘要

The present invention relates to a process for the preparation of a compound of the formula xLi ₂ MO _3. (1-x) LiM'O ₂ wherein M is Mn, Ti, Zr or any combination thereof and M ' , 0 x 1); And an outer layer formed by P ₂ O ₅ gas deposition. The present invention provides a method of making the coated lithium-rich layered oxide, a cathode comprising the coated lithium-rich layered oxide, and a rechargeable lithium battery.
