High voltage and safe electrolytes based on ionic liquid and sulfone for lithium-ion batteries

Interface modification in high voltage spinel lithium-ion battery by using N-methylpyrrole as an electrolyte additive

“…These results imply that the rate performance is dominated by the transportation of Li + through electrode/electrolyte interface in this case. Generally, a high resistance film formed on the cathode always hampers the Li + transport, thereby, increase the cell polarization and decrease the rate capability [38]. Since the interface between LiNi0.5Mn1.5O4 and electrolyte is stabilized by MPL built conductive network, Li + can more easily pass through the CEI film and make it insensitivity to rate variation.…”

A facile approach of introducing DMS into LiODFB–PYR14TFSI electrolyte for lithium-ion batteries

“…ethylene carbonate (EC) and diethyl carbonate (DEC)). [4][5][6][7] In order to tackle this limitation, ionic liquids combined with organic solvents appear to exert a positive inuence on application of ILs for lithium ion batteries. 2 Intensive research efforts have been devoted to ionic liquids (ILs), known as environmentally benign and 'designer' solvents, which exhibit low vapor pressures and wide electrochemical stability windows and are considered as a potential substitute for organic carbonates due to their advantage of non-ammability.…”

Three-dimensional-network Li3V2(PO4)3/C composite as high rate lithium ion battery cathode material and its compatibility with ionic liquid electrolytes

“…Ionic liquids (ILs), on the other hand, have been receiving greater attention in the lithium ion battery field because of their non-flammability, negligible vapour pressure, and high thermal, chemical, and electrochemical stability. Among the large family of ILs, pyrrolidinium bis(trifluoromethanesulfonyl) amide salts in particular show high cathodic stability against lithium metal, relatively high ionic conductivity, non-flammability and also good electrochemical properties in battery tests [23][24][25].…”
