NEGATIVE ACTIVE MATERIAL FOR RECHARGEABLE LITHIUM BATTERY, NEGATIVE ELECTRODE INCLUDING THE SAME AND METHOD OF PREPARING THE SAME, AND RECHARGEABLE LITHIUM BATTERY INCLUDING THE SAME

摘要

Provided are a negative active material for a rechargeable lithium battery, which includes a first silicon oxide (SiO_x) and a second silicon oxide (SiO_x) with a particle diameter differing from the one of the first silicon oxide (SiO_x), a negative electrode including the negative active material, and a method of manufacturing the negative electrode, and a rechargeable lithium battery including the negative electrode. The first silicon oxide (SiO_x) and second silicon oxide (SiO_x) have a particle distribution peak area ratio ranging from 3 to 8.
