Abstract
The present disclosure relates to an anode active material for a lithium secondary battery, a lithium secondary battery comprising the anode active material, and a method of preparing the anode active material. One embodiment of the present disclosure provides an anode active material for a lithium secondary battery, comprising a composite of SiO-carboxylmethyl cellulose (CMC)-carbon nanotube (CNT) in which CNT is bonded to SiO(0<x≦1) through CMC; and a carbon-based material. Also, another embodiment of the present disclosure provides a method of preparing an anode active material for a lithium secondary battery, comprising bringing SiO(0<x≦1) into surface-treatment with carbon nanotube (CNT) and carboxylmethyl cellulose (CMC) to form a composite of SiO-CMC-CNT; and mixing the composite of SiO-CMC-CNT with a carbon-based material.
