Professor Pan Feng’s research group has recently made important progress in the research of new solid electrolytes and high-energy density solid-state batteries. Lithium-containing ionic liquids ([EMI0.8Li0.2][TFSI]) are loaded into porous metals as guest molecules- In the organic framework material (MOF) nanoparticle carrier, a new type of composite solid electrolyte material was prepared.

　　The next generation of lithium batteries for electric vehicles and mobile phones will choose all-solid-state lithium-ion batteries with higher energy density and better safety. In order to accelerate the research and development of new materials and all-solid-state lithium-ion batteries, the country established the “Material Genome Technology” national key research and development plan for the first time during the “13th Five-Year Plan” period, and hopes to pass the high-throughput calculation, synthesis, detection and database (big data) of the material genome. The new concept and new technology of machine learning and intelligent analysis) accelerate the research and development of all-solid-state lithium-ion batteries, and set up a national key special project of "All-solid-state battery research and development based on material genome technology". As the chief scientist, Professor Pan Feng took the lead in organizing the joint responsibility of 11 units.

　　An important part of the project's research and development includes the research and development of high-performance all-solid-state lithium batteries and key materials (for example: new solid electrolytes, etc.) and mechanisms (for example: the control of each interface of solid-state battery materials, etc.). Traditional inorganic ceramic electrolytes have the disadvantages of large interface impedance and poor matching with electrode materials. At present, it is difficult to obtain large-scale application in the field of solid-state batteries. Therefore, the development of new solid-state electrolytes with smaller interface impedance has an impact on the energy density and electrochemical performance of solid-state batteries. Promotion is of great significance.

　　Among them, lithium-containing ionic liquids are responsible for lithium ion conduction, while porous metal-organic framework materials provide solid carriers and ion transmission channels, avoiding the risk of leakage of traditional liquid lithium-ion batteries, and at the same time, it has certain effects on lithium dendrites. Inhibition, so that metal lithium can be directly used as the negative electrode of solid-state batteries. The new solid electrolyte material not only has high bulk ionic conductivity (0.3mS·cm-1), but also has excellent interface lithium ion transport performance due to its unique micro-interface wetting effect (nano-wettedeffect), and The electrode material particles have good matching.
