An electrolyte for a lithium ion battery includes a vitreous eutectic mixture represented by the formula AB, where A is a salt chosen from a lithium fluoroalkylsulfonimide or a lithium fluoroarylsulfonimide, B is a solvent chosen from an alkylsulfonamide or an arylsulfonamide, and x and y are the mole fractions of A and B, respectively.

Lithium ion battery electrolyte including a vitreous eutectic mixture

Lithium salts with fluorinated chelated orthoborate anions are prepared and used as electrolytes or electrolyte additives in lithium-ion batteries. The lithium salts have two chelate rings formed by the coordination of two bidentate ligands to a single boron atom. In addition, each chelate ring has two oxygen atoms bonded to one boron atom, methylene groups bonded to the two oxygen atoms, and one or more fluorinated carbon atoms bonded to and forming a cyclic bridge between the methylene groups.
