Brief description of 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 electrolyte cost has been further reduced. Japanese and Korean companies It has also begun to transfer manufacturing plants to China. It is believed that in the near future, my country's electrolyte will go abroad and into the world. As lithium batteries are used more and more widely, 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 continue to discharge at a high rate. The main reason is that the battery lugs 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 electrolyte self-analysis and intensified side reactions between materials and electrolyte parts at high temperatures; at low temperatures, electrolyte salt precipitation and negative SEI film impedance may increase exponentially. The so-called wide temperature electrolyte is to make the battery have a wider working environment. 4. Safety The safety of electrolyte batteries is currently burning or even exploding. First of all, the battery itself is flammable. Therefore, when the battery is overcharged, overdischarged, short-circuited, When the outside temperature is too high, it may cause safety accidents. Therefore, flame retardancy is an important direction for the research of safe lithium battery electrolyte. After all, the 3C market is in small batches and many batches. With the development of the new energy vehicle market, the demand for power lithium batteries is very large. We have to stand higher, to meet the needs of new energy vehicles, and look at the electrolyte from the perspective of automobiles. Demand, there will be a new understanding of the electrolyte. Therefore, it is proposed that the industry be integrated. The existing electrolyte plants and battery plants must be integrated to meet the needs of new energy vehicles for batteries. Since the core technology of electrolyte products lies in additives, the current global electrolyte giants such as Japan's Mitsubishi Chemical, Japan's Ube, Samsung SDI, etc. have their own magical additive technology. They purchase raw materials and then carry out appropriate production and modification before proceeding. sell. Therefore, in the future, the development trend of the lithium battery electrolyte industry will gradually show that the company has mastered the core technology and reduced company costs and improved processing efficiency through outsourcing.
