【Abstract】 CMD sample was made by direction oxidive method following the densification.The diffusion of proton in MnO2 affects the electrochemical activity in the alkali battery.The results show the CMD reveals the characteristics of n-type semiconductor.The concentration and transference of proton in CMD after densification are increased.The wide diffusion way for proton is important to improve the discharge behavior of CMD in 9 mol/L KOH.更多还原
