Lithium solvation in dimethyl sulfoxide-acetonitrile mixtures [PDF]
, 2014 We present molecular dynamics simulation results pertaining to the solvation of Li+ in dimethyl sulfoxide-acetonitrile binary mixtures. The results are potentially relevant in the design of Li-air batteries that rely on aprotic mixtures as solvent media.
