Abstract
The invention is directed in a first aspect to an ionic liquid of the general formula Y+Z−, wherein Y+ is a positively-charged component of the ionic liquid and Z− is a negatively-charged component of the ionic liquid, wherein Z− is a boron-containing anion of the following formula:
The invention is also directed to electrolyte compositions in which the boron-containing ionic liquid Y+Z− is incorporated into a lithium ion battery electrolyte, with or without admixture with another ionic liquid Y+X− and/or non-ionic solvent and/or non-ionic solvent additive.
