Computational Electrochemistry. Voltages of Lithium-Ion Battery Cathodes
Theoretical studies on the electrode materials in lithium-ion batteries provide information on the structural changes during the charging and discharging processes. In the present study, we tested the M06-L and N12 exchange-correlation functionals on some well studied lithium-containing materials. These functionals, which have already shown good performance for a variety of databases, outperform the widely used PBE functional for reproducing the experimental structures and averaged intercalation potentials. It is especially noteworthy that the M06-L, functional gives voltages as accurate as those provided by the Heyd-Scuseria-Ernzerhof (HSE06) hybrid functional, but with less computational cost.
