In liquid electrolytes, the transport of lithium ions involves their movement within the solvent medium. In contrast, in crystalline solids, the conduction of lithium ions requires passing through periodic BN points, creating an energy barrier between two local energy minima. The conductivity of ions in liquid electrolytes can be improved in two ways: first, by increasing the dissociation of salts or ions in solvents of higher dielectric constants. This promotes the increase of the solvated ion. Second, reducing the viscosity of solvents facilitates the movement of solvated ions.
