高度分散在石墨烯薄片之间的硅纳米颗粒复合材料，由石墨烯堆叠区域重构形成的石墨三维网络支撑，具有高锂离子存储能力和循环稳定性。制备的电极在50次循环后的存储容量为> 2200 mA h g(-1)，在200次循环后的存储容量为> 1500 mA h g(-1)，每循环下降< 0.5%。
Composites of Si nanoparticles highly dispersed between graphene sheets, and supported by a 3-D network of graphite formed by reconstituting regions of graphene stacks exhibit high Li ion storage capacities and cycling stability. An electrode was prepared with a storage capacity > 2200 mA h g(-1) after 50 cycles and > 1500 mA h g(-1) after 200 cycles that decreased by < 0.5% per cycle.
