Abstract 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 2 278.0 F·g-1 at 1 A·g-1 and remarkable cycling stability of 93.7% capacitance retention after 2 000 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.
