Abstract
Free-solvent-free lithium sulfonimide salt compositions that are liquid at room temperature, and methods of making free-solvent-free liquid lithium sulfonimide salt compositions. In an embodiment, the methods include mixing one or more lithium sulfonimide salts with one or more ether-based solvents and then removing the free solvent(s) under suitable vacuum, temperature, and time conditions so as to obtain a free-solvent-free liquid lithium sulfonimide salt composition that is liquid at room temperature. In an embodiment, the only solvent molecules that remain in the liquid lithium sulfonimide salt composition are adducted with lithium sulfonimide salt molecules. An example automated processing system for making free-solvent-free liquid lithium sulfonimide salts is also disclosed.
