• We first report on H₁₁Al₂V₆O_23.2 with large layer spacing as cathode for aqueous zinc-ion battery, which accelerates the diffusion of Zn²⁺.

• The graphene-wrapped H₁₁Al₂V₆O_23.2 nanobelts can improve electronic conductivity, and potentially inhibit the dissolution of elements in the aqueous electrolyte.

• H₁₁Al₂V₆O_23.2@graphene exhibits high capacity and stable cycling stability even at an ultra-high mass loading of ~ 15.7 mg cm⁻².
