Aqueous zinc-ion batteries are plagued by poor energy density and cyclability of the metal anode. The anode-free configuration is an approach to improve the energy density by removing the metal anode and allowing the zinc in the electrolyte to deposit onto and strip off of the current collector, greatly improving zinc utilization. While this does improve energy density by reducing material input, it also results in greatly reduced cyclability without significant engineering of the current collector via nanostructuring, alloying, interface manipulation via surfactants, or some other approach that increases fabrication complexity and cost. Herein, we demonstrate how the incorporation of permanent magnets combined with simple, 2-dimensional geometry modifications can improve cyclability of anode-free zinc ion batteries with not only copper but also carbon current collectors. By placing a disc magnet directly behind the current collector, it can regulate the deposition of zinc via magnetohydrodynamics while remaining fully sequestered from any electrochemical activity, meaning the magnet remains unaltered over the battery’s lifetime for theoretically infinite recyclability. Additionally, the magnetic field not only reduced capacity fade, it also improved initial capacity, Coulombic efficiency, and on the carbon current collector, even open circuit potential, demonstrating the wide array of improvements this method offers.
