摘 要：<正>Ternary and quadruple lithium silicon nitride anode materials for lithium ion batteries with different precursors were prepared by the simple process of high-energy ball milling.High capacity and excellent cyclability were obtained.The influence of precursor introduction on the electrochemical performance of products was investigated.This research reveals that the electrochemical performance of lithium silicon ni- tride can be enhanced significantly by doping O.The cyclability of quadruple lithium silicon nitride can be optimized remarkably by control- ling the introduction quantity of the precursors.It is possible for the composite to be used as a capacity compensator within a wide voltage cut-off window.
