NEGATIVE ACTIVE MATERIAL FOR SECONDARY BATTERIES

摘要

The present invention relates to an anode material for a lithium secondary battery and, more specifically, to an anode material for a lithium secondary battery which is alloy including Si. Inside the alloy, an amorphous zone on a matrix or a microcrystal zone and the amorphous zone exists, while the amorphizing rate of the amorphous zone or the amorphizing rate or the microcrystal zone and amorphous zone is 30% or greater.
