Electrochemical performance of Zn-MnO2 cells in 3 M Zn(CF3SO3)2 electrolyte with 0.1 M Mn(CF3SO3)2 additive. a Discharge/charge profiles at varying C rates. b The Ragone plots of Zn-MnO2 battery and ZIBs with other reported cathode materials. Values are based on the total active mass of both cathode and anode. c Long-cycle performance at rate of 6.5 C. Inset shows the capacity evolution at the initial 19 cycles
