LITHIUM-TRANSITION METAL COMPLEX COMPOUNDS HAVING Nth ORDER HIERARCHICAL STRUCTURE, METHOD OF PREPARING THE SAME AND LITHIUM BATTERY COMPRISING AN ELECTRODE COMPRISING THE SAME

摘要

A lithium-transition metal complex compound has an nth order hierarchical structure in which n type structures represented by at least one unit of ath order units in a range of 1×10-(a+5) m to 10×10-(a+5) m exist in a complex form, wherein n is a natural number that is 2 or greater, and a is a natural number in a range of 1 to 5. The lithium-transition metal complex may be prepared by heat-treating a mixture including a lithium source, a transition metal source, and solvent in contact with a natural material having a hierarchical structure. A lithium battery includes an electrode including the lithium-transition metal complex compound having the nth order hierarchical structure. The lithium battery can have improved rapid charging characteristics, high power characteristics, and cycle characteristics.
