The limited ionic conductivities of these electrolytes indicate that high molecular flexibility alone does not guarantee fast ion transport in solid polymer electrolytes and that other factors, such as the polarity of the polymer host material, will also influence the transport properties of the electrolyte.
Another route to influence the ionic conductivity of ionic conducting materials is through modifying the microstructure.
Nevertheless, separators also increase electrical resistance and takes up limited space inside the battery, affecting ionic conductivity.
Therefore, extensive research work is devoted to enhance the ionic conductivity in LLT conducting garnets.

Unfortunately, the prominent problem of solid-state batteries is their low power densities compared with liquid-electrolyte lithium batteries, resulting from the low ionic conductivity of the solid electrolyte, the electrode/electrolyte interfacial compatibility, and limited kinetics of the electrodes [153, 154].
This led to the conclusion that limited use of intergranular additives to create superplastic Y-CSZ should not degrade the ionic conductivity for a specific engineered grain size.
These salts commonly exhibit ionic conductivity, which increases with temperature.
