Hierarchical Co-Ni Layered Double Hydroxide Nanosheets Enwrapped Cuo Nanorods by Electrodeposition for Excellent Energy Storage Devices

Published: Jan. 1, 2024

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.
