摘　　要：为提升超级电容器电极材料的电化学性能,在泡沫镍(NF)上以MOF为模板制备出NiCoP/C导电骨架,后将超薄NiMn-LDH纳米片沉积其上,制备得到核壳结构的NiCoP/C@NiMn-LDH复合材料。电化学测试结果表明,MOF模板的高比表面积、独特的核壳结构和NiCoP/C与NiMn-LDH之间的协同作用有利于电极材料性能的提升。制备得到的NiCoP/C@NiMn-LDH电极在1 A·g^(-1)下比电容可达2278.0 F·g^(-1);循环2000圈后电容保留率为93.7%。To improve the electrochemical performance of electrode materials for supercapacitors,the core-shell NiCoP/C@NiMn-LDH composite were synthesized on Nickel Foam(NF)with MOF-derived NiCoP/C as the conductive skeleton and decorated by ultra-thin NiCo-LDH nanosheets.The results show that NiCoP/C@NiMn-LDH electrode exhibits an excellent specific capacitance of 2278.0 F·g^(-1) at 1 A·g^(-1) and remarkable cycling stability of 93.7%capacitance retention after 2000 cycles.It is concluded that the high specific area of MOF template,the core-shell structure and the synergy between NiCoP/C and NiMn-LDH contribute to the electrochemical performance.
