摘要：
A method for manufacturing a cathode active material for a lithium rechargeable battery, including: selecting a first metal compound from a group consisting of a halide, a phosphate, a hydrogen phosphate and a sulfate of Mg or Al; selecting a second metal compound from a group consisting of an oxide, a hydroxide and a carbonate of Mg or Al; combining the first metal compound and the second metal compound to obtain a metal compound, the metal compound containing either Mg or Al atoms; mixing a lithium compound, a transition metal compound and the metal compound to obtain a mixture; and sintering the mixture.
