Owing to ease of recyclability, high theoretical capacity (820 mAh g \u22121 ), safety, facile manufacture, and high energy density, Zinc\u2010ion capacitors (ZICs) are emerging as promising capacitors and have attracted substantial attention. However, aqueous ZICs frequently encounter several difficulties, comprising low coulombic efficiency, low Zn anode deposition\/stripping efficiency, hydrogen evolution, fast capacity decay, and Zn dendrite formation. Hence, to inhibit the formation of Zn dendrites, it is important to tune the electrolyte and the electrode\/electrolyte interface. Herein, the key problems are tackled by using choline\u2010based electrolytes. ZIC with ZnCl 2 in the presence of choline chloride yields good capacity and inhibits Zn dendrite formation due to the adsorption of choline at the interface. To further increase the energy density of the device, redox\u2010active choline anthraquinone sulphonate (ChAQS) additives are synthesized and incorporated into the ChCl\/ZnCl 2 system. The constructed graphene\u2010based aqueous ZIC with the novel (ChCl\/ ChAQS \/ZnCl 2 ) electrolyte system shows a high specific capacity of 460 F g \u22121 and a high energy density of 185 Wh kg \u22121 at 0.25 A g \u22121 . These outcomes demonstrate an innovative pathway to fabricate biobased redox electrolytes for emerging sustainable energy storage devices.<\/p>\n","protected":false},"excerpt":{"rendered":"
