This paper ‘Improved lithium storage properties of Mg2Si anode material synthesized by hydrogen-driven chemical reaction’ is published on Electrochemistry Communications 25 (2012) 15-18.
Nanocrystalline Mg2Si with high purity, homogeneous composition and uniform particle size was successfully synthesized by a facile hydrogen-driven chemical reaction at below 500 °C. The as-prepared Mg2Si exhibited an improved Li-ion storage ability as anode material for Li-ion batteries as it delivered an initial capacity of about 1095 mAh/g at 100 mA/g. The discharge capacity stayed at 406 mAh/g after 60 cycles, which is much better than that of the commercialMg2Si anode and previously reportedMg2Si anode synthesized bymechanical alloying. The proof-of-concept synthesis technique presented in thiswork should be valuable for the preparation of other intermetallic compounds with difference of melting point between the constituent elements.
