ELECTROLYTE FORMULATION FOR NICKEL-RICH CATHODE AND SILICON-RICH ANODE BATTERY CELLS

An electrolyte, a battery cell, and a vehicle with a vehicle battery is provided. The electrolyte includes a ternary salt, dual-cyclic solvents, a linear carbonate solvent, and quaternary additives. The ternary salt includes lithium hexafluorophosphate (LiPF), lithium bis(fluorosulfonyl)imide (LiFSI), and lithium difluoro(oxalate)borate (LiDFOB). The dual-cyclic solvents include ethylene carbonate (EC) between 0-30% by volume and fluoroethylene carbonate (FEC) between 0-30% by volume. The linear carbonate solvent includes at least one of ethyl methyl carbonate (EMC), dimethyl carbonate (DMC), or diethyl carbonate (DEC). The linear carbonate solvent is between 60-80% by volume. The quaternary additives include vinylene carbonate (VC) between 0.5-2% by weight, trimethylsilyl (TMSi) between 0.25-1% by weight, bis(2,2,2-trifluoroethyl) carbonate (DFDEC) between 0.5-2% by weight, and succinic anhydride (SA) between 0.25-1% by weight.
