Abstract
The present disclosure provides a novel composite transition metal oxide-based precursor, a preparing method thereof, and a cathode active material for a secondary battery prepared from the precursor. In the present disclosure, it is possible to enhance productivity and economic efficiency due to a high reaction yield during the synthesis of a cathode active material and to enhance the initial discharge capacity and lifespan characteristics of a secondary battery including a cathode active material by using an oxide-based precursor having a high oxygen fraction instead of a hydroxide-based precursor used as a precursor of a cathode active material in the related art.
