What are the development trends of lithium battery electrolyte?

The development trend of lithium battery electrolyte: As far as my country’s current lithium battery electrolyte market is concerned, the barriers to entry are not high, but there are barriers to invisible technology. With the localization of key raw materials, the current cost of electrolyte is also Following the further decline, Japanese and Korean companies have also begun to transfer their manufacturing plants to the country. It is believed that in the near future, my country's electrolyte will go abroad and into the world. As the application fields of lithium batteries become more and more extensive, all kinds of lithium batteries have different requirements for their electrolytes. Next, the author analyzes the electrolyte, the key raw material for lithium batteries, on the development trend of the electrolyte. 1. High specific energy electrolyte pursuing high specific energy is currently the biggest research direction of lithium batteries, especially when mobile devices occupy more and more proportions in people's lives, battery life has become the most critical performance of batteries. 2. High-power electrolyte. At present, it is difficult for commercial lithium batteries to achieve high-rate continuous discharge. The main reason is that the battery tabs generate serious heat, and the internal resistance causes the overall temperature of the battery to be too high, which is prone to thermal runaway. Therefore, the electrolyte should be able to prevent the battery from heating up too quickly while maintaining high conductivity. Regarding power lithium-ion batteries, fast charging is also an important direction for electrolyte development. 3. Wide-temperature electrolyte lithium batteries are prone to the decomposition of the electrolyte itself and the intensification of the side reactions between the material and the electrolyte parts at high temperatures; at low temperatures, there may be electrolyte salt precipitation and the negative electrode SEI film impedance doubled. The so-called wide temperature electrolyte is to make the battery have a wider working environment. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
