Moreover, RPTs display a decreasing trend in cell capacity, even at slower cycling rates, suggesting that the active sites on the cathode material responsible for zinc storage were depleting. 62 In published reports, the lower initial capacity of EMD has been attributed to the mixture of phases (ε-MnO 2 (53%), ramsdellite (34%), and γ-MnO
