ANODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY, METHOD FOR MANUFACTURING SAME, AND LITHIUM SECONDARY BATTERY COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2016/053031

Kind Code:

A1

Abstract:

The present invention relates to an anode active material for a lithium secondary battery, a method for manufacturing the same, and a lithium secondary battery comprising the same. The anode active material comprises a surface-treated silicon nanoparticle, wherein the surface-treated silicon nanoparticle comprises a silicon nanoparticle and a surface treatment layer which is positioned on the surface of the silicon nanoparticle and includes crystalline SiO2, so that the anode active material, when being applied to a battery, can exhibit excellent lifespan and capacity characteristics as well as remarkably improved initial efficiency characteristics.
