The evaluation of self-diffusion, viscosity, and ionic conductivity highlights the importance of striking the right balance between lithium salt and G3 solvent, in particular for possible applications as an electrolyte system for batteries. Adding G3 to the lithium salt results in a significantly improved mobility of all particles in the system. However, for high G3 concentrations, the mixture's ionic conductivity is harmed due to the decreasing charge density. Therefore, a well-considered trade-off between different properties of the system needs to be found.
