This work was aimed to investigate a new type of solid state lithium (Li) ion conductor as electrolyte for all solid-state Li-ion batteries. A metal organic framework (MOF) MIL-121 was modified in two different ways in order to become Li-ion conductive. The post synthetic modifications (PSM) were lithiation with lithium acetate (LiAc) and lithium hydroxide (LiOH) as well as esterification of the carboxylic groups of MIL-121 with methanol (MeOH), ethanol (EtOH) and isopropanol. After PSM the porous samples were soaked with different liquids like common liquid electrolytes, which leads to a…mehr

This work was aimed to investigate a new type of solid state lithium (Li) ion conductor as electrolyte for all solid-state Li-ion batteries. A metal organic framework (MOF) MIL-121 was modified in two different ways in order to become Li-ion conductive. The post synthetic modifications (PSM) were lithiation with lithium acetate (LiAc) and lithium hydroxide (LiOH) as well as esterification of the carboxylic groups of MIL-121 with methanol (MeOH), ethanol (EtOH) and isopropanol. After PSM the porous samples were soaked with different liquids like common liquid electrolytes, which leads to a decreased activation energy of Li-ion jumps in the crystal lattice meaning an increased Li-ion conductivity of the material. Esterified MIL-121 was soaked with ionic liquids containing lithium bis(trifluoromethane)sulfonimide (LiTFSI), because the introduction of Li-ions to the structure was necessary.
