The melting curve of lithium was computed using the \\textit{Z}-method technique for pressures up to 30 GPa, which agrees well with the experimental and two-phase simulated results. The change of the melting line slope from positive to negative was predicted by the characteristic shape inversion of the \\textit{Z} curve at about 8.2 GPa.
