A hierarchical structure consisting of Co-Ni layered double hydroxide nanosheets (LDH-NSs) enwrapped copper oxide nanorods (CuO-NRs) was synthesized in situ on the surface foam (CF) through direct oxidation and electrodeposition methods. The CF skeleton provided desired electrical conductivity, while in-situ CuO-NRs eliminated need for binders. Moreover, uniform growth LDH-NSs via facilitated formation a stratified structure, effectively inhibiting aggregation providing ample active sites adsorption/desorption transportation electrolyte ions. Adjusting molar ratio Co2+ to Ni2+ influenced electrochemical properties, resulting efficient growth, porous morphological control. CF@CuO@Co-Ni LDH-2 (Co: Ni=1:2) sample demonstrated most favorable performance, primarily attributed its superior Ni: Co synergistic effect. As wonderful electrode material, it exhibited high specific capacitance 2628.4 F g−1 at current density 2 g−1. Even after 5,000 cycles 20 g−1, maintained an outstanding retention rate 95.00 %. expected, assembled asymmetric supercapacitor displayed remarkable energy 101.54 Wh kg-1. impressive 87.57 % 10,000 This study highlighted potential materials prepared applications. method preserved all components carrier improved utilization sites, avoiding use adhesives, templates, or surfactants, simplifying procedure.

The preparation of porous carbon is constrained by the extensive use and detrimental impact activators dopants. Therefore, developing green efficient strategies that leverage intrinsic properties pretreatment materials to achieve self-activation self-doping particularly crucial for materials. Herein, potassium histidine was utilized as molecular salt precursor, attaining streamlined through a one-step carbonization process enables self-activation, self-doping, self-templating. More interestingly, temperature significantly impacts structure precursors, heteroatoms, electrochemical performance. designed electrodes exhibit high accessibility electrolyte ions effective ion-electron transport channels. optimal material (KHis800) has an excellent mass-specific capacitance 305.2 F g
