In the present research, we utilized the single-folding model to develop a systematical optical potential for ${}^6\mathrm{Li}$ and ${}^7\mathrm{Li}$, employing the nucleon-nucleus global potentials introduced by Koning and Delaroche (KD02). We analyzed the elastic scattering angular distributions of ${}^6\mathrm{Li}$ and ${}^7\mathrm{Li}$ on targets with mass numbers ranging from 24 to 209 using the single-folding potential. Incident energies between 5 and 55 MeV/nucleon were considered. The real part of the single-folding model potential was renormalized with one free parameter, while leaving its imaginary part unchanged. The resulting renormalization factors of the single-folding model potentials show consistent systematics. Our approach effectively reproduced the elastic scattering and reaction cross sections of the targets in our current study. In addition, we also compared the prediction abilities of our systematic optical potentials with those of others.
