Here, mesoporous NiCo 2 S 4 nanosheet fibre‐shaped electrode was prepared using Ni–Co layered double hydroxide (LDH) grown on nickel wire as precursor. NiCo 2 S 4 nanosheet electrode displayed excellent electrochemical properties with specific capacitance of 1974.55 mF/cm 2 at 2 mA/cm 2 and 86.2% capacitance retention after 5000 cycles, which were far higher than those of Ni‐Co LDH precursor. Our work provides new strategy to improve the performance of LDH used for supercapacitor.
