ANODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY, LITHIUM SECONDARY BATTERY INCLUDING SAME, AND METHOD FOR MANUFACTURING ANODE ACTIVE MATERIAL |
| 摘要 |
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 x -carboxylmethyl cellulose (CMC)-carbon nanotube (CNT) in which CNT is bonded to SiO x (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 x (0<x‰¤1) into surface-treatment with carbon nanotube (CNT) and carboxylmethyl cellulose (CMC) to form a composite of SiO x -CMC-CNT; and mixing the composite of SiO x -CMC-CNT with a carbon-based material. The anode active material and the lithium secondary battery of the present disclosure provide enhanced battery capacity, as well as improved life characteristics as compared with those having SiO surface-treated with only carbon nanotube. |
