Abstract

An example electrolyte includes a solvent mixture, a lithium salt, a non-polymerizing solid electrolyte interface (SEI) precursor additive, and a solvent additive. The solvent mixture includes dimethyl carbonate (DMC) and fluoroethylene carbonate (FEC) present in a volume to volume ratio ranging from 20 to 1 to 1 to 20. The non-polymerizing SEI precursor additive is present in an amount ranging from greater than 0 wt % to about 10 wt % of a total wt % of the electrolyte, and the solvent additive is present in an amount ranging from greater than 0 wt % to about 10 wt % of the total wt % of the electrolyte.
