Lithium battery new design or reduce dependence on rare metals

The results show that the key to enhance battery performance is solid polymer electrolyte. Researchers tested the new several variants of solid-state batteries to analyze its 50 ℃ high temperature in more than 300 times the performance of the charging and discharging cycle. Now new research has shown great potential, but the next step, the researchers must make new batteries instead of rare metal electrode of lithium ion batteries have the same capacity, and attenuation also meets the requirements, the state grid marks can we truly consider commercialized. Formula of heat transfer temperature difference polymer-based electrolyte has two outstanding advantages, one is in the loop when bending and adapt to fluoride iron swelling ability, 2 it is with iron to form very stable fluoride flexible interface, solved the previous battery design of using iron fluoride in key problems such as inflation and a large number of side effects. This lead to competition for raw materials such as cobalt and nickel increasingly fierce competition, and even to ensure the rare metal is already a national issue. Whether pure electric vehicles or renewable energy batteries, rare metals are necessary materials. According to the latest issue of 'nature & sdot; In the future, researchers will continue to improve and develop new solid electrolyte, in order to realize the fast charge, and the fusion of solid and liquid electrolyte in the new design, the best way to avoid monitoring with large battery factory is fully compatible with conventional batteries used in the manufacturing technology. Heat transfer temperature difference formula to calculate the new cathode active material and solid polymer (by iron fluoride A kind of plastic) Electrolyte nano composite materials. Cheaper than cobalt and iron 300 times, 150 times cheaper than nickel. To make the cathode, the researchers developed a solid polymer electrolyte penetration into the prefabricated iron fluoride electrode method, and then hot pressing the whole structure, in order to increase density and reduce the gap. This is expected to bring safer, lighter and cheaper lithium ion batteries. State grid marks the industrial silicon quotation analysis in addition, iron lithium fluoride capacity is a traditional cobalt base or more than twice the nickel-based cathode. Material 'report, in order to develop the lithium battery replacement, reduce the dependence on rare metal, the Georgia institute of technology researchers have developed a promising new cathode and electrolyte system, with lower cost of transition metal fluorides and solid polymer electrolyte instead of the expensive metal and traditional liquid electrolyte. So scientists set out to explore alternatives, the industrial silicon quotation analysis to alleviate dependence. When's the best way to avoid monitoring used with solid polymer electrolyte, even at high temperature, metal fluorides also showed remarkable stability.
