Two-dimensional (2D) metal-organic frameworks (MOFs) with bimetallic coupling effect exhibit excellent supercapacitor performance.Using 2,6-Naphthalic acid (2,6-NDC) as the organic ligand and cobalt and nickel as the metal centers,a bimetallic CoNi-MOF material with 2D nanosheet structure was synthesized via one-step solvothermal method.This material was applied as an energy storage material for pseudo-capacitive supercapacitors.The results showed that the CoNi-1∶1 electrode achieved a specific capacitance of 816.1F/g at 0.5A/g and possessed a minimum charge transfer resistance of 0.15Ω.After assembling it with activated carbon (AC) to form a hybrid supercapacitor (HSC),CoNi-1∶1//AC,the voltage window was extended to 1.8V.At 1A/g,the energy and power densities were 78.9Wh/k and 3582.3W/kg,respectively,demonstrating its broad application prospect in energy storage field.
