Abstract
The present invention provides a positive electrode active material which includes a lithium transition metal oxide particle, composite particles, and at least one kind of conductive oxide particle on the lithium transition metal oxide particle surface, and also provides a preparation method for the positive electrode active material. The positive electrode active material includes lithium transition metal oxide particles and particular conductive oxide particles and composite particles which have a single phase, and thus the positive electrode active material not only has superb electronic conductivity, while having excellent ion transfer capability which allows transfer of metal ions such as lithium ions to lithium transition metal oxide particles, but may also minimize capacity reduction and output reduction in a secondary battery.
