摘要： Disclosed are a novel one-body particle for cathode active materials including a core and a coating layer formed on at least a part of the core, wherein the coating layer contains Co and a structure-stabilizing element, the core is present as a non-aggregated primary particle, and the structure-stabilizing element has a bond dissociation energy (BDE) with oxygen (O) greater than a bond dissociation energy (BDE) of Co and oxygen (O), and a method of preparing a novel one-body powder containing the same.
