Alkaline total-iron flow battery and preparation method of electrode material

The invention discloses an alkaline total-iron flow battery and a preparation method of an electrode material. The alkaline total-iron flow battery is characterized in that a positive electrolyte of the alkaline total-iron flow battery takes ferrocyanide as an active substance and one or two of NaOH and KOH as supporting electrolyte, and a negative electrolyte of the alkaline total-iron flow battery takes complex iron formed by reaction of 3-[N-N-bis (2-ethoxyl) amino]-2-hydroxypropanesulfonic acid and ferric chloride as an active substance and one or two of NaOH and KOH as supporting electrolyte. And one or two of NaOH and KOH are used as supporting electrolyte to form the alkaline total-iron flow battery. The reaction active sites of the positive and negative electrode electrolyte active substances on the surface of the electrode are respectively increased, so that the charge and discharge capacity of the flow battery is improved. 本发明公开了一种碱性全铁液流电池及电极材料的制备方法。其特征是：所述的碱性全铁液流电池的正极电解液是以亚铁氰化物为活性物质，NaOH和KOH中的一种或两种
