MANUFACTURING METHOD OF COMPOSITE OF LITHIUM NICKEL OXIDE AND LITHIUM MANAGANESE OXIDE AND COMPOSITE OF LITHIUM NICKEL OXIDE AND LITHIUM MANAGANESE OXIDE MADE BY THE SAME

摘要

The present invention relates to a method for producing a composite of lithium nickel oxide and lithium manganese oxide, and a composite of lithium nickel oxide and lithium manganese oxide produced by the same and, more specifically, to a method for producing a composite of lithium nickel oxide and lithium manganese oxide that has a long life at a room temperature and at a high temperature and shows excellent safety even after repeated charging and discharging at a high current, and a composite of lithium nickel oxide and lithium manganese oxide produced by the same. The method for producing a composite of lithium nickel oxide and lithium manganese oxide according to the present invention does not use simple mixing between lithium nickel oxide and lithium manganese oxide but produces a composite by granulation based on grinding, spray drying and heat treatment after mixing. Accordingly, high energy density and high output can be achieved within a short period of time. Also, excellent safety and long-term life characteristics are shown.
