The low structural stability and sluggish charge-transfer kinetics of transition metal phosphides (TMPs) hinder their application in hybrid supercapacitors. realization advanced OH- storage critically depends on the delicate TMP designs, particularly chemical composition structure. Herein, a synergistic engineering approach based metal-organic framework (MOF)-derived C-coated bimetallic P vacancies (Pv) was proposed. Using Ni-Co-based MOF, one-step high-temperature carbonization phosphidation method employed as precursor to prepare rose-like Ni1-xCoxP composite (Ni1-xCoₓP@NC), comprising N-doped carbon (NC) coating Pv. Physical characterization theoretical calculations indicated that open structure with porous Ni1-xCoxP@NC nanosheets originating from pyrolysis MOF provides abundant redox-active sites, NC layer offers excellent mechanical support for persistent electron/OH- transfer. phosphides, surface Pv, synergistically enhance electrical conductivity TMPs, reduce energy barriers adsorption, accelerate kinetics. prepared @NC electrode possessing an architecture exhibits high specific capacitance (2,108 F g-1 at 1 A g-1) rate capability (1,710 10 g-1). Furthermore, assembled active carbon//Ni1-xCoxP P@NC supercapacitor demonstrates density 37.7 Wh kg-1 power 750 W kg-1. Our study presents promising strategy modifying electrodes realize efficient stable
