Solvents in salt electrolyte: Benefits and possible use as electrolyte for lithium-ion battery
An EC/DEC [40:60% (v/v)] solvent mixture has been added in various amounts to the ionic liquid (IL) hexyltrimethylammonium bis(trifluoromethylsulfonyl)imide (N 1116-NTf 2) in the presence of LiNTf 2 (lithium bis(trifluoromethylsulfonyl)imide) as lithium salt for possible use as electrolytes in lithi...
