Unlocking Mo, P co-doping to boost proton intercalation in MnO2 as a high-performance cathode material for aqueous zinc-ion batteries

Mo, P co-doping can reduce the insertion energy of H + , which is beneficial to the intercalation of H + , and explains the increase in the contribution of H + intercalation. The capacity of Mo, P–MnO 2 is 216 mA h g −1 after 1100 cycles.
