Title:
ANODE ACTIVE MATERIAL PRECURSOR FOR LITHIUM SECONDARY BATTERY, ANODE ACTIVE MATERIAL MANUFACTURED USING SAME, AND LITHIUM SECONDARY BATTERY COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2013/183974
Kind Code:
A1
Abstract:
The present invention relates to an anode active material precursor for a lithium secondary battery, an anode active material manufactured using the same, and a lithium secondary battery comprising the same, and more specifically, to: an anode active material precursor for a lithium secondary battery characterized in that a ratio of a length in an a-axis direction to a length in a c-axis direction in a plurality of primary particles having the length in the a-axis direction that is different from the length in the c-axis direction increases from the center of a secondary particle to the surface thereof in a combination oxide of the anode active material precursor and lithium, which is the secondary particle comprising a transition metal, formed by congregating the plurality of primary particles, and having an average particle size within a range of 4-20 μm; an anode active material; and a lithium secondary battery comprising the same.
