Electrolyte Formulations for Ultra-Fast Chargeable Battery Electric Vehicle Cell

An electrolyte for a battery cell, a battery cell for a vehicle, and a method of forming an electrolyte. The electrolyte includes a carbonate solvent, a primary lithium salt present in the solvent at a concentration in the range of 0.6 M to 2.0 M, a secondary lithium salt optionally present in the solvent at a concentration in the range of 0.1 M to 0.5 M. The electrolyte further includes a phenyl additive including at least one of a fluorine substituent and a fluorinated substituent, the phenyl additive present in an amount of 0.5 percent by weight to 20 percent by weight of the total weight of the electrolyte, and a co-additive present in the range 0.1 weight percent to 20 weight percent of the total weight of the electrolyte.
