Tin dioxide is a promising sodium storage material due to its great theoretical capacity of sodium storage. Graphene has good mechanical properties and electrical conductivity as an ideal conductive additive. However, SnO2/reduced graphene oxide (RGO) composite has a large specific surface area and its initial Coulombic efficiency is low, thus affecting the application. In this paper, SnO2/RGO composites were synthesized by a hydrothermal method, and C/SnO2/RGO composites were alos prepared via filling the pitch pyrocarbon. The results show that SnO2 in C/SnO2/RGO composite is uniformly distributed in RGO with the size of 6 nm. The initial Coulomic efficiency of C/SnO2/RGO nanocomposite with pitch pyrocarbon filling is improved, which is nearly 25% greater than that of SnO2/RGO composite. The specific capacities of SnO2/RGO and C/SnO2/RGO composites are 442.1 and 479.8 mA·h/g, respectively, after 100 cycles. The addition of pitch pyrocarbon results in an increase in cycle stability, and the material impedance is improved, thus increasing the electrons and ionic conductivity among SnO2 particles, RGO and pitch pyrocarbon.

SnO2的储钠理论容量高,是很有前景的储钠材料,石墨烯导电性和力学性能良好,是理想的电极材料辅助材料。然而与石墨烯复合后获得的SnO2/还原氧化石墨烯(RGO)复合材料比表面积大,首次Coulomb效率低,影响了材料的规模应用。采用水热法,原位合成了SnO2/RGO复合材料,并成功填充沥青炭制备了C/SnO2/RGO复合材料。结果表明:C/SnO2/RGO复合材料中SnO2均匀分布在RGO结构中,晶粒尺寸约6 nm;沥青炭填充后的C/SnO2/RGO首次Coulomb效率显著提高,比SnO2/RGO提高近25%;100次循环以后SnO2/RGO和C/SnO2/RGO复合材料容量保持分别为442.1和479.8 mA·h/g;沥青炭的加入使得循环稳定性显著增加,材料的阻抗得到了大幅度改善,增加了SnO2粒子、RGO以及沥青炭之间的电子以及离子传导性。

SnO2的储钠理论容量高,是很有前景的储钠材料,石墨烯导电性和力学性能良好,是理想的电极材料辅助材料。然而与石墨烯复合后获得的SnO2/还原氧化石墨烯(RGO)复合材料比表面积大,首次Coulomb效率低,影响了材料的规模应用。采用水热法,原位合成了SnO2/RGO复合材料,并成功填充沥青炭制备了C/SnO2/RGO复合材料。结果表明:C/SnO2/RGO复合材料中SnO2均匀分布在RGO结构中,晶粒尺寸约6 nm;沥青炭填充后的C/SnO2/RGO首次Coulomb效率显著提高,比SnO2/RGO提高近25%;100次循环以后SnO2/RGO和C/SnO2/RGO复合材料容量保持分别为442.1和479.8 mA·h/g;沥青炭的加入使得循环稳定性显著增加,材料的阻抗得到了大幅度改善,增加了SnO2粒子、RGO以及沥青炭之间的电子以及离子传导性。

Tin dioxide is a promising sodium storage material due to its great theoretical capacity of sodium storage. Graphene has good mechanical properties and electrical conductivity as an ideal conductive additive. However, SnO2/reduced graphene oxide (RGO) composite has a large specific surface area and its initial Coulombic efficiency is low, thus affecting the application. In this paper, SnO2/RGO composites were synthesized by a hydrothermal method, and C/SnO2/RGO composites were alos prepared via filling the pitch pyrocarbon. The results show that SnO2 in C/SnO2/RGO composite is uniformly distributed in RGO with the size of 6 nm. The initial Coulomic efficiency of C/SnO2/RGO nanocomposite with pitch pyrocarbon filling is improved, which is nearly 25% greater than that of SnO2/RGO composite. The specific capacities of SnO2/RGO and C/SnO2/RGO composites are 442.1 and 479.8 mA·h/g, respectively, after 100 cycles. The addition of pitch pyrocarbon results in an increase in cycle stability, and the material impedance is improved, thus increasing the electrons and ionic conductivity among SnO2 particles, RGO and pitch pyrocarbon.
