NOVELTY - Constructing zinc ion hybrid capacitor based on ruthenium oxide/carbon material composite anode involves dispersing the carbon material and ruthenium chloride uniformly in water, adjusting the pH to neutral, filtering, washing the obtained precipitate, drying and then calcining to obtain a hydrated ruthenium oxide/carbon material composite material. The carbon material and ruthenium chloride are uniformly dispersed in water and then transferred to a reactor for hydrothermal reaction. The obtained precipitate is washed, dried, and then calcined to obtain a hydrated ruthenium oxide/carbon material composite material. USE - Method for constructing zinc ion hybrid capacitor based on ruthenium oxide/carbon material composite anode. ADVANTAGE - The method combines advantages of ruthenium oxide material and carbon material for storing zinc ion and uses the synergistic effect between the two, improving electron and ion transmission behavior in zinc ion mixed capacitor, to obtain zinc ion mixed capacitor with excellent electrochemical performance, it has important significance for the actual application of the zinc ion mixed capacitor. DETAILED DESCRIPTION - Constructing zinc ion hybrid capacitor based on ruthenium oxide/carbon material composite anode involves dispersing the carbon material and ruthenium chloride uniformly in water, adjusting the pH to neutral, filtering, washing the obtained precipitate, drying and then calcining to obtain a hydrated ruthenium oxide/carbon material composite material. The carbon material and ruthenium chloride are uniformly dispersed in water and then transferred to a reactor for hydrothermal reaction. The obtained precipitate is washed, dried, and then calcined to obtain a hydrated ruthenium oxide/carbon material composite material, mixed the hydrated ruthenium oxide/carbon material composite material, the conductive agent, and the binder to form a slurry, and coated on the current collector to obtain the hydrated ruthenium oxide/carbon material composite positive electrode, assembled zinc ion hybrid capacitor in the order of zinc metal negative electrode, a separator with dripped electrolyte, and a hydrous ruthenium oxide/carbon material composite positive electrode.
