摘要:

以天然海藻为原料, 经条件优化制备了含杂原子的碳材料SarCW-900及LamCW-900, 对其形貌、 元素成分、 孔性质和石墨化程度进行分析并讨论其活化机理. 将2种材料作为电化学电容器及锂离子电池的电极材料活性物质, 分别进行电化学性能测试. 结果表明, SarCW-900及LamCW-900在被用作电化学电容器电极材料时, 比电容分别为106 F/g及85 F/g, 经5000次循环伏安稳定性测试, 比电容值稳定在101 F/g及81 F/g, 分别降低不到4%和5%, 是理想的电容器电极材料; 在被用作锂离子电池电极材料时, 经100次循环比容量分别保持在100.3及33.9 mA·h/g, 低于纯石墨的理论值, 但具有较高的稳定性.

Abstract:

Heteroatom-containing carbon materials SarCW-900 and LamCW-900 were prepared using two types of seaweeds as raw materials. The morphology, elemental composition, pore properties, graphitization degree and the activation mechanism of the carbon materials were discussed. The two carbon materials were used as electrode material in electrochemical capacitor and lithium-ion batteries, and the results of electrochemical measurements showed that the specific capacitance of SarCW-900 and LamCW-900 was 106 and 85 F/g, respectively. After 5000 voltammetry cycles, the specific capacitance was stabilized at 101 and 81 F/g, which decreased by only 4% or 5% respectively, indicating that SarCW-900 and LamCW-900 are ideal capacitor electrode materials. When they were used as lithium-ion battery electrode material, the specific capacity after 100 cycles was maintained at 100.3 and 33.9 mA·h/g for sarCW-900 and LamCW-900, respectively, lower than the theoretical value of pure graphite, but more stable.
