摘要

Si-TiN alloys were prepared by reactive gas mechanical milling of Si and Ti powders in N-2(g) for use as anode materials in Li-ion cells. This is a low-cost and simple method to prepare Si-TiN anode materials. As a comparison, Si-TiN alloys were also synthesized more conventionally by ball milling Si and TiN powders in Ar. Both Si-TiN alloys have similar phase compositions, however the Si-TiN alloys prepared by N-2 reactive gas milling have a more homogenous TiN distribution at the nanometer-scale. As a consequence, Si-TiN alloys prepared by N-2 reactive gas milling where much more resistant to Li15Si4 formation during cycling in Li-cells, resulting in improved cell performance.
