Regulating the manganese cathode interface of zinc-manganese batteries with a quasi-eutectic electrolyte
(a) Schematic diagram of the structure and potential, and (b) schematic diagram of mass-charge transfer. φ represents the potential at different distances from the cathode interface. The substitution of OTf– by urea at the cathode interface achieves an increase in cathodic potential while differentiating the kinetics of desolvation of Mn2+ and Zn2+. This modulation of the cathode interface ultimately results in a high-capacity, long-cycle battery. Credit: Science China Press
