摘要

实验首先采用改进的Hummers法制备氧化石墨，然后以氧化石墨烯为前驱体，通过水热法将锡酸钴纳米颗粒均匀镶嵌在石墨烯薄膜基片上，最终获得Co2SnO4/Graphene镶嵌复合材料. 采用X射线衍射（XRD）、扫描电子显微镜（SEM）对材料的结构和形貌进行表征，通过恒电流充放电（CC）、循环伏安法（CV）与交流阻抗法（EIS）测试了材料的电化学性能. 实验结果表明，石墨烯良好的分散性及较高的电子导电率，可以提高锡酸钴材料的电化学性能，材料首次可逆容量达到1415.2 mA·h/g，50次循环后仍能保持469.7 mA·h/g的放电比容量.

Abstract

Co2SnO4/graphene composite has been prepared by multi-step synthetic process. Firstly, the formation of Co2SnO4 and the reduction of graphene oxide (GO) occur simultaneously during the hydrothermal process and the Co2SnO4 particles are uniformly embedded in the film-like graphene to form a mosaic structure. To characterize the phase and morphology of the composite material, X-ray diffraction (XRD), scanning electron microscope (SEM) are used. The constant current charge and discharge (CC), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) are also used to test the electrochemical performance of Co2SnO4/graphene composite. Results show that graphene can effectively improve the electrochemical performance of Co2SnO4/graphene composite by its good dispersibility and high electrical conductivity. The composite material exhibits a first discharge specific capacity of 1415.2 mA·h/g with the specific capacity still higher than 469.7 mA·h/g after 50 cycles.
