ELECTROLYTE FOR LITHIUM-ION BATTERIES WITH SILICON-BASED ANODES

An electrochemical cell has an anode comprising a silicon-based active material, a cathode comprising a cathode active material, and an electrolyte. The electrolyte is formulated with a propionate-based solvent, a carbonate-based solvent, trifluoro toluene, a lithium salt with a molar concentration of 2.0 M or greater, and less than or equal to 5.0 wt. % of fluoroethylene carbonate.
