A thermal ink jet ink composition includes one or more volatile organic solvents, wherein the one or more volatile organic solvents comprise a solvent selected from C-Calcohols, C-Cketones, C-Cesters, C-Cethers, and mixtures thereof. The one or more volatile organic solvents are present in an amount at least 60% by weight of the ink composition. The ink composition includes one or more binder resins present in an amount from 1% to 10% by weight of the ink composition, and one or more dyes. If water is present, it is present in amount less than 5% by weight of the ink composition. The ink composition includes less than 2% by weight of any humectant and/or wetting agent with a relative evaporation rate less than 0.3. The ink composition is suitable for use in a thermal ink jet printer.

A liquid catholyte for a Li&#x2014;S battery comprises a non-aqueous solution of at least one lithium polysulfide of formula LiS(wherein x is selected from 4, 6, and 8) and an anion receptor compound capable of complexing with polysulfide anion. The non-aqueous solution typically is composed of the LiSand the anion receptor compound dissolved in a non-aqueous solvent (e.g., one or more organic ether or fluorinated ether solvents). The anion receptor compound typically is present in the catholyte at a concentration of about 0.1 M to about 4 M. Li&#x2014;S batteries comprise a metallic lithium anode; a porous conductive substrate; a separator membrane between the anode and the porous conductive substrate; and the liquid catholyte composition within pores of the substrate.
