Abstract:
Disclosed is a negative active material for a rechargeable lithium battery including ultra-fine particles comprising an element which is capable of alloying with lithium. The particles have a diameter of 1 nm to 200 nm, a Raman shift of 480 cm−1 to 520 cm−1 measured by Raman Spectroscopy, and a full width at half-maximum of 10 cm−1 to 30 cm−1.
