AI Technical Summary
Existing electrolysis processes, especially those involving metals and alloys such as titanium and aluminum, suffer from high energy consumption, stringent requirements for electrode materials, poor compatibility and stability, and difficulty in using them in conjunction with advanced electrode materials such as novel inert anodes, thus limiting the development and improvement of electrolysis technology.
A low-temperature molten salt system, including AxBFy and an electrolytic stabilizer, is adopted, with preferred compositions such as KAlF4, K2TiF6, and Na2SiF6. Combined with an inert anode and a wettable cathode, DC electrolysis is performed at 700~850℃ to optimize the physicochemical properties of the molten salt, reduce the electrolysis temperature and equipment wear, and improve compatibility with new electrode materials.
It achieves low-temperature electrolysis operation, significantly reduces energy consumption and equipment wear, improves the stability and efficiency of the electrolysis process, is suitable for high-efficiency DC electrolysis, and is compatible with new electrode materials.
