In August 2017, a major breakthrough was made by Chongqing Tiantai Aluminum Industry Co., Ltd. and the Chongqing Institute of Technology for the “new low-energy electrolytic aluminum new technology based on the combination of a new anode and a heterotypic cathode” and supported by the Chongqing Science and Technology Commission. Application development major projects.

The joint project centered around the issue of high energy consumption in aluminum electrolyzers, and simultaneously improved the cathode and anode process structures of the electrolyzer, effectively reducing the thickness of the anode bubble layer and reducing the amplitude of aluminum fluid fluctuations. During this period, through the research and establishment of a physical and chemical property testing system and platform for aluminum electrolytes, the project investigated the effects of molecular ratios, additives and other parameters on the physical and chemical properties of aluminum electrolytes, and used Tiantai Aluminum Aluminum Electrolysis Big Data to research and develop suitable materials. Low-temperature, low-resistance electrolyte system for heterotypic cathode-perforated anode aluminum cells.

At the same time, the project aims at optimizing the structure of the copper plate by calculating the thermoelectric coupling field of the anode steel jaws for the problem of high resistivity of the steel claws, thereby reducing the pressure drop of the steel claws. By August 2017, the average voltage of the three experimental electrolyzers was 3.75V, the current efficiency was increased from less than 90% to 91%, and the DC power consumption was reduced to 12282kWh/t-Al. The results were obtained by the Chongqing technological invention. Awards.
