HIGH DENSITY ANODE ACTIVE MATERIAL AND PREPARATION METHOD THEREOF

摘要

An anode active material of the present invention can comprise a lithium metal oxide having an inner porosity of 3-8 % and an average diameter (D50) of 5-12 mum. According to the present invention, a small amount or the same amount of a binder is used by comprising the lithium metal oxide having a high density when it is necessary to prepare an anode slurry, thereby remarkably improving the adhesive strength of an anode. In addition, a high rate characteristic of a secondary battery can be improved by reducing the average diameter of the lithium metal oxide.
