Abstract

The Si/TiN/C composite anode was synthesized by pyrolyzing the as-prepared nano-Si/TiN powder and polyvinyl chloride (PVC). It could be observed that amorphous carbon was formed onto the surface of the Si/TiN particles to be the Si/TiN/C-1 and Si/TiN/C-2 composites. In particular, at a higher rate of 1 C, the charge capacities decreased from 2439.34 mAh g-1 to 1634.74 mAh g-1 for the Si/TiN/C-2 composite after 100 cycles, with the little capacity loss of 0.33 %. Consequentially, the continuous morphology and conductive network promoted the high rate capability and good cycle stability of Si/TiN/C composite anode.
