POSITIVE ACTIVE MATERIAL COMPOSITE FOR LITHIUM SECONDARY BATTERY, METHOD OF PREPARING THE SAME, AND LITHIUM SECONDARY BATTERY USING THE SAME

摘要

The present invention relates to a positive active material composite for a lithium secondary battery, a manufacturing method thereof, and a lithium secondary battery using the same. More specifically, the present invention relates to a positive active material composite for a lithium secondary battery capable of improving thermal stability, capacity, rate capability and lifetime property of a lithium secondary battery using the same by providing the positive active material composite, which is manufactured by coating the surface of a positive active material with metal oxide and directly growing carbon nanotubes thereon in manufacturing a positive active material for a lithium secondary battery; a manufacturing method thereof; and a lithium secondary battery using the same.
