Aqueous zinc-based batteries are promising candidates for the grid-scale energy storage owing to their nonflammability, ecofriendliness, and low cost. Nevertheless, their practical applications are hindered by the relatively low capacity and energy density. Herein, we develop a quasi-solid-state aqueous zinc-dual halogen battery composed of freestanding carbon cloth-iodine cathode and in situ prepared concentrated aqueous gel electrolyte.
