The present invention provides a novel lithium composite metal oxide containing nickel (Ni), cobalt (Co), and titanium (Ti) as main components, and the lithium composite metal oxide is a positive electrode active material for lithium secondary batteries with high charging capacity and When applied with an anode active material having a high energy density and has life characteristics, the optimum performance of a lithium secondary battery can be realized. In particular, since it is possible to maintain an optimum balance with the charging/discharging efficiency of the Si-based anode active material, a high-performance lithium secondary battery The battery can be manufactured. |
