Analyze the future battery star solid-state lithium battery

How about solid-state lithium batteries In addition to the mainstream ternary lithium battery and lithium iron phosphate battery markets, solid-state lithium batteries are also receiving more and more attention and are called the new star battery in the future. The traditional liquid lithium battery is called a rocking chair battery, which has positive and negative poles at both ends and a liquid electrolyte in the middle. When lithium ions move back and forth on both ends of the rocking chair like an athlete, the battery will charge and discharge as the lithium ions move from the positive electrode to the negative electrode and then to the positive electrode. On the other hand, solid-state batteries have solid electrolytes. The density and structure of the electrolyte allow more charged ions to gather at one end, conduct more current, and increase the capacity of the battery. From the perspective of technical potential, it is relatively difficult to increase the energy density of ternary lithium-ion power lithium-ion batteries, but it is theoretically more feasible to increase the energy density of all-solid-state lithium batteries. First of all, the voltage platform of the solid lithium battery has been improved. Solid electrolytes have a wider electrochemical window than organic electrolytes, which is beneficial to further increase the energy density of the battery. Second, the solid electrolyte can isolate the dendrite growth of lithium, and the scale of the material application system has been greatly improved, laying the foundation for new lithium battery technology with higher energy density space. Third, the current energy density of the all-solid-state lithium battery is about 400wh/Kg, and the maximum potential value is estimated to be 900wh/Kg, there is more than 100% room for improvement. Solid lithium batteries inherit the advantages of traditional lithium batteries and have made great progress in safety and energy density. At present, the energy density of all-solid-state lithium batteries can be as high as 300~400Wh/kg, which is expected to become an important development direction of the next generation of high-energy-density power and energy storage battery technology, and it is also the consensus of academia and industry. In short, the lithium iron phosphate circuit is being replaced, the ternary lithium battery circuit has become the mainstream, all solid lithium batteries or new lithium battery circuits will gradually replace the ternary lithium battery. The health and large-scale promotion and application of new energy vehicles in the future depend to a large extent on the support strength of high-safety and long-distance power lithium-ion batteries. At present, the advancement of new energy vehicle power lithium-ion battery technology will be driven by national policies and the dual pressure of external competition, requiring the continuous improvement of existing ternary lithium battery skills, together with new lithium battery technologies and breakthroughs, in order to complete the disruptive Innovation. For battery companies, this is the best time and the worst time. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
