摘　　要：采用简单的水热-磷化热解法合成高性能的NiCoP/石墨烯(GS)复合电极材料.采用X射线衍射、拉曼光谱和透射电镜对材料的结构进行表征.利用循环伏安(CV)和恒流充放电(GCD)对材料的电容性能进行测试.结果表明,粒径为10~20 nm的NiCoP纳米粒子均匀地负载在石墨烯上.当其作为电极材料应用于超级电容器中时,展示出良好的电化学性能,在1 A/g时,其比电容为896 F/g.5000次循环后,其比电容保持率为87.9%.The high performance of NiCoP/Graphene nanocomposite material was fabricated by hydrothermalphosphorization treatment route.The structure of CoNiP/Graphene nanocomposite was determined via X-ray diffraction,transmission electron microscopy and raman spectroscopy methods.The capacitve properties of the NiCoP/Graphene nanocomposite was measured by CV and GCD.The results indicated that CoNiP nanoparticles with particle size of 10~20 nm were dispersed uniformly on graphene.When being assembled as an electrode for supercapactior,the CoNiP/Graphene nanocomposite exhibited excellent capacitive properties,a high specific capacitance of 896 F/g at 1 A/g,the capacitance retention over 87.9%after 5000 cyles.
