  Lithium chloride LiCl is widely used as a prototype system to study the
strongly dissociated 1-1 electrolyte solution. Here, we combined experimental
measurements and classical molecular dynamics simulations to study the ion
conduction in this system. Ionic conductivities were reported at both
20$^\circ$C and 50$^\circ$C from experiments and compared to results from
molecular dynamics simulations. The main finding of this work is that
transference numbers of Li$^+$ and Cl$^-$ become comparable at high
concentration. This phenomenon is independent of the force fields employed in
the simulation and may be resulted from the ion-specific concentration
dependence of mobility.
