- Аннотация: Autonomous and portable electronic devices require cheap energy storage unitsof ever-increasing power and energy densities. Zinc/halogenate flow battery isproposed as a new type of reserve or emergency power supply unit. The batteryuses a mechanically rechargeable zinc anode in contact with neutral aqueous saltelectrolyte, cation-exchange membrane, and a carbonaceous flow throughcathode, at which aqueous acidified halogenate is reduced to halide in a sixelectronprocess. A new multielectron oxidizer, aqueous iodate, that can be usedin other electrochemical power sources, is introduced. It is shown that iodate canbe readily reduced in acidic media at cheap carbonaceous electrodes.Electrochemical experiments with stationary and rotating disk glassy carbonelectrodes reveal that in acidic aqueous electrolytes reduction of iodate can be asfast as earlier studied reduction of bromate. Theoretical energy densities perreactants of Zn/bromate and Zn/iodate batteries are 1.2 and 1.45 kWh L1,respectively. Area-specific power of the single cells of these batteries reaches0.57Wcm-2 at 50 oC.
