摘要
以碳化硅冶炼炉同步生产石墨化太西煤为原料,采用改良的Hummers氧化还原法制备了煤基石墨烯,通过FT-IR和XRD对其进行了表征,并利用循环伏安、恒电流充放电等电化学测试方法对其电化学性能进行了测试。结果表明:煤基石墨烯具有良好的电化学性能,在电流密度0.5A·g^(-1)下,充放电1000次后煤基石墨烯电极材料的比电容量为105.5F·g^(-1)。
Coal-based graphene were prepared from graphited Taixi anthracite by Silicon Carbide Furnace with an improved Hummers method.The composite was studied by FT-IR and XRD.The electrochemical behavior of thecomposite electrode was evaluated by cyclic vohammetry （CV） and galvanostatic charge-discharge tests with a two-electrode system.Results show that the specific capacitance of the coal-based graphene as an electrode in a su- percapacitor is 105.SF·g^-1 after 1000 cycles at a current density of 0.SA·g^-1
