Abstract: This invention relates to a process for manufacturing lithium nickel cobalt oxide-based cathode compounds for lithium ion secondary batteries. As part of this process, nickel, cobalt, and optionally manganese-bearing precursor compounds are lithiated and sintered at a high temperature. When cooled down, a high cooling rate will benefit the throughput of the process and the economics. It has however been found that the cooling rate should not exceed 10° C./min in what has been determined to be a critical temperature domain, ranging from 700° C. to 550° C.
