Ion Clusters and Networks in "Water-in-Salt Electrolytes"
Michael McEldrew, Zachary A. H. Goodwin, Sheng Bi +2
Water-in-salt electrolytes (WiSEs) are a class of super-concentrated electrolytes that have shown much promise in replacing organic electrolytes in lithium-ion batteries. At the ex…
Theory of Ion Aggregation and Gelation in Super-Concentrated Electrolytes
Michael McEldrew, Zachary A. H. Goodwin, Sheng Bi +2
In concentrated electrolytes with asymmetric or irregular ions, such as ionic liquids and solvent-in-salt electrolytes, ion association is more complicated than simple ion-pairing.…
Adding salt to expand voltage window of humid ionic liquids
Ming Chen, Jiedu Wu, Ting Ye +5
Humid hydrophobic ionic liquids, widely used as electrolytes, have narrowed electrochemical windows, because their water, absorbed on the electrode surface, gets involved in electr…
Molecular understanding of charge storage and charging dynamics in supercapacitors with MOF electrodes and ionic liquid electrolytes
Sheng Bi, Ming Chen, Runxi Wang +4
We present a computational microscopy analysis (targeted molecular dynamics simulations) of the structure and performance of conductive metal organic framework (MOF) electrodes in…
Kinetics of Ion Transport in Ionic Liquids: Two Dynamical Diffusion States
Guang Feng, Ming Chen, Sheng Bi +4
Using classical molecular dynamics simulations, we investigate the mobility of ions in [Bmim][TFSI], a typical room temperature ionic liquid. Analyzing the trajectories of individu…
