영문 초록

Ti-Si alloys are synthesized by mechanical alloying method and their electrochemical properties as anode materials for lithium ion batteries are investigate. The mechanically alloyed Ti-Si samples consist of active Si and inactive TiSi 2 phases. The electrochemical performance of Ti-Si alloys are dependent on the alloy composition of Ti/Si ratio, attributable to the ratio of active/inactive phases. With increasing the active Si phase, the cycle performance is getting worse, while the reversible charge capacity increases. The poor cycle performance with high Si phase is attributed to the electrical disconnection between active material particles or between active material particles and current collector and SEI film regeneration on the surface of Ti-Si alloy particles during cycling.
