rGO wrapped SiOx with ordered meso-porous structure material is fabricated via a facile route. This meso-porous SiOx/rGO composite, used as anode in LIBs, exhibits a reversible capacity of 580 mAh g⁻¹ under the applied current density of 100 mAg⁻¹ up to 200 cycles. And it still can deliver a reversible capacity of 120 mAh g⁻¹ even at 10,000 mA g⁻¹ rate. The high cyclic stability and superior rate performance is attributed to the graphene layer as well as the inert products formed in the reduction of SiOx, which can buffer the volume expansion elastically, thus preserve the integrity of the electrode. Moreover, the ordered meso-porous structure can provide high specific surface area, sufficient void space to shorten the pathway of Li ions, improve the electrolyte penetration and enhanced the electrochemical Li ion storage.

rGO包裹的SiOx具有有序的介孔结构材料，是通过一条便捷的途径制造的。在LIB中用作阳极的这种介孔SiOx / rGO复合材料在施加的100 mAg ^-1的电流密度下（最多200个循环）显示出580 mAh g ^-1的可逆容量。即使在10,000 mA g ^-1时，它仍可提供120 mAh g ^-1的可逆容量。速度。高循环稳定性和优异的倍率性能归因于石墨烯层以及在SiOx还原过程中形成的惰性产物，可以弹性缓冲体积膨胀，从而保持电极的完整性。而且，有序的中孔结构可以提供高的比表面积，足够的空隙空间以缩短Li离子的路径，改善电解质的渗透性并增强电化学Li离子的存储。
