The pressure-dependence of the ionic conductivity was calculated by using mode-coupling theory. The required equilibrium structure was obtained by using the hypernetted-chain integral equation. The pressure-dependence of the molar ionic conductivity exhibited a maximum value which was consistent with experiment. The conductivity slightly exceeded the value that was predicted by the Nernst–Einstein equation. It was also consistent with molecular dynamics simulations and experiment.
