NEGATIVE ELECTRODE ACTIVE MATERIAL FOR SECONDARY BATTERY AND SECONDARY BATTERY INCLUDING THE SAME |
摘要 |
Provided are a negative electrode active material for a secondary battery, in which a silicon-based negative electrode active material is formed in a three-layer structure including an amorphous matrix, thereby suppressing a dispersal phenomenon of the negative electrode active material during charging/discharging. The negative electrode active material having a three-layer structure includes: a silicon (Si) layer; an amorphous matrix layer outside the Si layer; and a nano grain matrix layer formed on an interface between the Si layer and the amorphous matrix layer. |
