abstract = {The influence of urea on the conducting salt lithium
bis-(trifluoromethanesulfonyl)-imide (LiTFSI) in terms of
lithium ion coordination numbers and lithium ion transport
properties is studied via atomistic molecular dynamics
simulations. Our results indicate that the presence of urea
favors the formation of a deep eutectic electrolyte with
pronounced ion conductivities which can be explained by a
competition between urea and TFSI in occupying the first
coordination shell around lithium ions. All simulation
findings verify that high urea concentrations lead to a
significant increase of ionic diffusivities and an
occurrence of relatively high lithium transference numbers
in good agreement with experimental results. The outcomes of
our study point at the possible application of deep eutectic
electrolytes as ion conducting materials in lithium ion
batteries.},
