【Abstract】 Chronoamperometry and cyclic voltammetry were employed to study the reduction and diffusion behavior of ferrate(VI)ion in NaOH solution.Diffusion coefficient of ferrate(VI)ion had been directly calculated on platinum micro-disk electrode.The impact of the mass transfer of ferrate(VI)ion in electrolyte on the super-iron battery which was in high rate discharging had also been discussed.In addition,the experiment results of cyclic voltammetry indicated that the electrochemical reduction of ferrate(VI)ion involved more than one step.更多还原
