Summary: Recently, Prussian blue analogues (PBAs) have attracted considerable attention as efficient battery-type electrode materials for advanced hybrid supercapacitors. In this study, carbon nanotubes- (CNTs) and carbon nanofibers- (CNFs) hybridized NiHCC nanocomposites were successfully synthesized using a single-step hydrothermal process for investigating their battery-type electrochemical storage behavior in 3 M KOH. The synthesized electrodes exhibited battery-type charge storage mechanisms with excellent stability. Specifically, the NiHCC-CNT composite (NiHCC@CNT) electrode showed outstanding charge storage capacity (348 mAh g-1 at 1 Ag-1) due to its high electrochemically active surface area, low charge transfer resistance, and efficient utilization of redox centers for K+ ion storage. Furthermore, the hybrid capacitor constructed with NiHCC@CNT demonstrated excellent cycling stability over 5000 cycles, with a maximum energy density of 59 W h Kg- 1 at a power density of 1798 W Kg-1. This work highlights the potential of NiHCC@CNT composite as a cathode material for K+ ion supercapacitors.
