Solid State Li-Ion Batteries

Li-ion batteries dominate the portable electronics market. However, the current electrode materials are still far away from satisfying the large energy density required for various applications (e.g. electric vehicles). Solid inorganic electrolytes become quite important at this point that can enable the use of high capacity electrode materials, which are otherwise not very stable and safe to be used in liquid electrolytes. Li7La3Zr2O12 and doped variants are especially interesting solid electrolyte candidates with high Li-ion conductivities in the range of ~ 10-4 S/cm at RT and with possible large thermal operation windows, up to 1000˚C.
