Abstract
A bimodal-type positive electrode active material includes a first lithium composite oxide as a small particle and a second lithium composite oxide as a large particle, which improves the transport ability of lithium ions by controlling the morphology or crystal structure of the small particle included in the positive electrode active material, and further alleviates or prevents the early deterioration or shortened lifetime of the bimodal-type positive electrode active material, caused by the small particle, by increasing the particle stability of the small particle. A lithium secondary battery using the bimodal-type positive electrode active material is also provided.
