    Abstract: An example of a three-electrode test cell includes a negative electrode, a positive electrode having an aperture defined therein, a reference electrode, and a first microporous polymer separator soaked in an electrolyte. The reference electrode is disposed within the aperture of the positive electrode and physically separated from the positive electrode. The first microporous polymer separator is disposed between the negative electrode and the positive electrode.

    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.

    Abstract: An electrolyte solution for a lithium sulfur battery contains a lithium oxalatoborate compound in a 0.05-2 M solution in conventional lithium sulfur battery electrolyte solvents, optionally with other lithium compounds. Examples of solvents include dimethoxyethane (DME), dioxolane, and triethyleneglycol dimethyl ether (TEGDME). Electrochemical cells contain a lithium anode, a sulfur-containing cathode, and a non-aqueous electrolyte containing the lithium oxalatoborate compound. Lithium sulfur batteries contain a casing enclosing a plurality of the cells.
