MANUFACTURING METHOD OF LITHIUM CONTAINING METAL OXIDE AND LITHIUM SECONDARY BATTERY USING SAME

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a lithium containing metal oxide capable of improving an output property and a lithium secondary battery using the same.

SOLUTION: A lithium manganese complex oxide is synthesized by mixing a manganese dioxide and a lithium carbonate and burning for 7 hours at 900 °C in air. An alkali component is removed from a particle surface by adding distilled water of 10 times weight to the synthesized complex oxide and stirring for one hour to wash it. The battery is produced by using the complex oxide from which the alkaline component have been removed, as a positive active material, accordingly, elimination/insertion of lithium ions during charging and discharging is not impeded.
