Document Type and Number:
WIPO Patent Application WO/2012/033369
Kind Code:
A3
Abstract:
The present invention relates to a method for preparing a positive electrode active material for a lithium secondary battery. More particularly, the method for preparing a positive electrode active material for a lithium secondary battery according to the present invention comprises the following steps: mixing a nickel source, a cobalt source, an aluminum source, ammonia water, sucrose and a pH control agent so as to prepare a mixture solution; drying and oxidizing the mixture solution so as to prepare a positive electrode active material precursor; and adding a lithium source to the positive electrode active material precursor and firing the precursor so as to prepare a positive electrode active material for a lithium secondary battery.
