| description | The invention discloses a preparation method of an alkaline all-iron flow battery electrode material, which comprises the following steps: uniformly mixing ferrous salt, a surfactant and water according to a certain proportion range, then soaking a graphite felt pretreated by nitric acid in the mixed liquid, adding a sodium hydroxide solution to adjust the pH value to 8-9, adding an oxidant for oxidation, and finally, carrying out vacuum drying to obtain the alkaline all-iron flow battery electrode material. And adjusting the pH value of the impregnated mixture to 10-13 by using a sodium hydroxide solution at 90-100 DEG C, refluxing for 1-3 hours, finally taking out the graphite felt, washing, and carrying out vacuum drying, thereby obtaining the ferroferric oxide modified graphite felt electrode material. And reaction active sites of positive and negative electrode electrolyte active substances on the surface of the electrode are obviously increased. The preparation method has the advantages of easily availa |
