Rational design and structural regulation of hybrid nanomaterials with superior electrochemical performance are crucial for developing sustainable energy storage platforms. Among these materials, NiCo-layered double hydroxides (NiCo-LDHs) demonstrate an exceptional charge capabilities owing to their tunable 2D lamellar structure, large interlayer spacing, rich redox electrochemically active sites. However, NiCo-LDHs still suffer from sever agglomeration particles limited transfer rates, resulting in inadequate rate capability. In this study, bimetallic ZnCo-metal organic framework (MOF) tripods were grown on the surface NiCo-LDH nanowires, which significantly reduced self-agglomeration stacking nanowire arrays, offering more accessible sites shortening path ion diffusion. The fabricated ZnCo-MOF@NiCo-LDH its individual counterparts tested as supercapacitor electrodes. electrode demonstrated a remarkable specific capacitance 1611 F g-1 at 2 A enhanced capability 66% 20 g-1. Moreover, asymmetric all solid-state device was constructed using palm tree-derived activated carbon (P-AC) positive negative poles, respectively. can store high 44.5 Wh Kg-1 deliver power 876.7 W outstanding Columbic efficiency over 10,000 charging/discharging cycles 15
