Abstract

Carbon cathodes have shown excellent electrochemical behavior in aluminum batteries based on non-aqueous electrolytes. By contrast, their use in Al systems operating in a salt-water medium is plagued by poor and unstable performance. Herein, it is sustained that a successful C cathode for rechargeable aqueous Al batteries requires surface customization to enable hydrophilicity and grafting of charged Al molecules. Employing a freeze-dried reduced graphene oxide (rGO) as the active electrode material, an aqueous Al-C battery is assembled with a high energy density (136 Wh kg−1 per cathode mass) and one of the best capacity retentions reported (≈60% across a range of current densities and constant Coulombic efficiencies close to unit). Furthermore, the rGO cathode more than doubles the benchmark for life cycles (to ≈200 cycles) and can be charged rapidly (
