REDOX FLOW BATTERY THAT REVERSIBLY CONVERTS CHEMICAL ENERGY INTO ELECTRICITY

摘要

The invention relates to a redox flow battery that can be used to convert chemical energy into electricity in a reversible manner, comprising: - an anolyte tank (1), containing species of a redox couple, - a catholyte tank (2), containing species of another redox couple, and - at least one electrochemical cell (10), in which a flow of anolyte (A) originating from and sent back to the anolyte tank circulates, in which a flow of catholyte (C) originating from and sent back to the catholyte tank circulates, and which is provided with two electrodes (13), which are respectively in contact with the flow of anolyte (A) and with the flow of catholyte (C), and which collect an electric charge/discharge current of the redox flow battery. The flow of anolyte and the flow of catholyte in the electrochemical cell are laminar, and, in the electrochemical cell, a laminar flow of electrolyte (E) also circulates which is inserted between the flow of anolyte (A) and the flow of catholyte (C) so as to form, at the same time, a first liquid-liquid interface between the flow of anolyte and the flow of electrolyte and a second liquid-liquid interface between the flow of catholyte and the flow of electrolyte.
