Title : Research on solid electrolytes for lithium batteries


Solid electrolytes are the key materials to solve the safety problem of lithium metal batteries and all-solid-state lithium batteries. They can reduce the side reaction and prevent lithium dendritic breaking through electrolytes, and therefore, improve the cycling stability and safety of lithium metal batteries. This presentation briefly shows the research progress on Li-ion solid state electrolytes in my group in recent years, including NASICON-type LiZr2(PO4)3, Garnet-type Li7La3Zr2O12, perovskite-type Li3/8Sr7/16Hf1/4Ta3/4O3 ceramic electrolytes and organic-inorganic composite solid electrolytes. The modification on interfaces between electrolyte and electrodes were also studied.
