Whether the common "salt bath" on the market can prolong the life of lithium battery

　　(1) Today, I bring you a very interesting technology "salt bath". It is reported that salt bath for rechargeable lithium ion batteries can extend the life of lithium batteries, and may even break through the limitation of the service life of rechargeable lithium ion batteries. This technology comes from Australian research organization and has a good commercial prospect.

　　(2) The Commonwealth Scientific and Industrial Research Organization (CSIRO) of Australia said on Thursday that its scientists had invented a simple salt bath method, which can extend the life of rechargeable lithium-ion batteries and break the bottleneck of battery life. On Thursday, CSIRO scientists invented a simple salt bath method, which can extend the life of rechargeable lithium-ion batteries, And it may break the battery life bottleneck of electric vehicles. CSIro cooperated with the Academy of the Royal Melbourne University of Technology and the Queensland University of Science and Technology, and found that after the battery assembly, the lithium metal electrode can be immersed in the mixed electrolyte containing ionic liquid and lithium salt, which can extend the battery life, improve performance and safety. Ionic liquid, also known as room temperature molten salt, is a transparent, colorless, tasteless and flame retardant ordinary liquid. These materials can form a protective film inside the electrode to maintain the stability of the battery during use, and handle rechargeable batteries that are prone to fire and explosion. In addition, treated batteries can be stored for up to one year without loss of performance. Adimbest, a battery expert at CSIRO, said that theoretically, the battery pretreated in this way is better than any traditional lithium-ion battery on the market. The new generation of power lithium battery is the key to the development of electric vehicle industry. This simple salt bath pretreatment will accelerate the development of a new generation of energy storage methods to cope with the anxiety of current battery life. In the electric vehicle industry, after improving battery life and charging capacity, electric vehicles can compete with traditional vehicles in the near future. Anthony bull, associate professor of Queensland University of Technology; According to Anthony battery manufacturer, it is easy to adopt new battery production process by replacing the existing production line. The mixed electrolyte used in the salt bath contains a variety of chemical components, and CSIRO has a patent. Researchers are developing batteries based on this technology and looking for partners to commercialize them.

　　(3) At present, this technology is really helpful to solve the life problem of rechargeable lithium ion batteries, but it is far from practical application and commercialization. It is possible that our existing rechargeable lithium ions can be treated with this technology in the near future to help them extend their service life. This prospect is undoubtedly very attractive!
