Zusammenfassung:	The invention provides a preparation method and application of a zinc potassium hexacyanoferrate/carbon cloth composite electrode material, and relates to the technical field of electrochemistry. The preparation method of the zinc potassium hexacyanoferrate/carbon cloth composite electrode material comprises the following steps: S1, carrying out hydrophilic treatment on carbon cloth to obtain hydrophilic carbon cloth; s2, the hydrophilic carbon cloth serves as a working electrode, a zinc salt solution serves as an electro-deposition precursor solution, and elemental zinc is electrochemically deposited on the surface of the hydrophilic carbon cloth under the condition of constant current; s3, after the reaction is finished, taking out the carbon cloth, washing the carbon cloth with deionized water, and performing vacuum drying to obtain an elemental zinc/carbon cloth composite material; and S4, placing the elemental zinc/carbon cloth composite material in a potassium ferricyanide aqueous solution, carrying out
