High solubility positive electrolyte was prepared by chemical oxidation and electrochemical oxidation, and high solubility negative electrolyte was prepared by chemical coupling and electrochemical reduction. At the same time, the electrochemical reaction window of positive and negative electrolyte was located within the electrochemical window of water decomposition; The anion exchange membrane for hydrophilic flow battery with high strength and electrochemical corrosion resistance was prepared by continuous thermally induced phase separation method; Continuous laser welding and integrated molding technology are used to realize the preparation of non leakage liquid flow battery stack.
The R & D team of the company, together with relevant domestic universities such as University of science and technology of China and Changzhou University, has overcome the technical barriers of high water solubility, high purity, wide voltage window and low-cost anode and cathode electrolytes, overcome the technical bottleneck of industrialized production of anion exchange membranes with high strength, low resistance, low swelling and corrosion resistance, achieved the production of non permeable stacks, and broken the international technical barriers. We have developed the whole process low-energy production process and key equipment preparation technology, and formed independent intellectual property rights. The products of this project have low cost, high yield, green production, and strong market competitiveness.
