The claimed group of inventions relates to the energy industry, particularly, to electrochemical technologies for energy accumulation and storage, and it relates to a method for preparing a precursor for electrolytes of an all-iron flow battery and to a method for producing electrolytes based on this precursor. According to the first invention, the method for preparing the precursor comprises steps of mixing an iron chloride crystal hydrate and distilled water, while simultaneously passing an inert gas through a solution during its formation, separating the solution into two parts and reducing Fe3+ to Fe2+ in one of the parts, and oxidizing, in another part, Fe2+ ions to form Fe3+ ions in an electrochemical cell during a charging process. At the same time, an excess of a reducing agent may be added to the solution prior to the step of separating. The claimed method allows to purify the reduced part of the solution from Fe impurities and to stabilize a content of Fe2+ ions therein. According to the second invention, the electrolytes are produced from the reduced part of the precursor solution by adding electrically conductive additives and successively adjusting an acidity to a specific limit. The electrolytes are produced under vigorous stirring and heating, while the negative electrolyte is produced in an inert gas or hydrogen atmosphere. Said solution allows to provide a stable composition of the electrolytes and to ensure a high round-trip efficiency of the all-iron batter
