Si / TiN Nanocomposites Novel Anode Materials for Li ‐ Ion Batteries

Nanocomposites containing silicon and titanium nitride were synthesized by high‐energy mechanical milling. The process results in very fine particles distributed homogeneously inside the matrix. nanocomposites synthesized using different experimental conditions were evaluated for their electrochemical properties. Results indicate that in the composite alloys and dealloys with lithium during cycling, while remains inactive providing structural stability. A composite containing obtained after milling exhibited a stable capacity of , suggesting its promising nature. Preliminary cycling data show good capacity retention reflective of good phase and microstructural stability as verified by X‐ray diffraction and scanning electron microscopy analyses. ©2000 The Electrochemical Society
