SiO_x-based materials have become the most promising anode material of lithium-ion batteries because of their ultra-high theoretical specific capacity, rich in natural resources, environmentally benign, and relatively low working potential. Unfortunately, the tremendous change in the volume of SiO_x-based anode during the charging and discharging process will cause damage to the structure and rapid capacity fading, which dramatically hampered the further application of SiO_x-based anode materials. The synthesis of SiO_x/C composites with a honeycomb‐like structure is an effective way to relieve the volume variation and improve electrochemical performance. Because the composites with superior structural integrity can facilitate the contact of active materials. Besides, the rich pores in this honeycomb‐like structure can not only accommodate the volume expansion but also increase the area between the active materials and electrolyte. As anode materials for lithium-ion batteries, the composites delivered a high reversible capacity of 802 mAh g⁻¹ after 300 cycles at the current density of 200 mA g⁻¹. This simple synthesis method may provide a pathway to further application for SiO_x-based anodes of lithium-ion batteries.

SiO _x基材料由于其超高的理论比容量，丰富的自然资源，对环境无害以及相对较低的工作潜力，已成为锂离子电池最有希望的负极材料。不幸的是，在充电和放电过程中基于SiO _x的阳极体积的巨大变化将导致结构损坏和快速的容量衰减，这极大地阻碍了基于SiO _x的阳极材料的进一步应用。SiO _x的合成具有蜂窝状结构的/ C复合材料是缓解体积变化和改善电化学性能的有效方法。因为具有优异结构完整性的复合材料可以促进活性材料的接触。此外，这种蜂窝状结构中的富孔不仅可以容纳体积膨胀，还可以增加活性物质和电解质之间的面积。作为锂离子电池的负极材料，复合材料经过300次循环后，在200 mA g ^-1的电流密度下具有802 mAh g ^-1的高可逆容量。这种简单的合成方法可以为进一步应用锂离子电池的SiO _x基阳极提供一条途径。
