    Abstract: An electrolyte solvent having a dielectric constant of 10 or less comprising: a) 0% to 30% by volume of one or more of components i)-iii), based on a total volume of the electrolyte solvent: i) one or more unsubstituted cyclic carbonate(s): ii) one or more unsubstituted lactone(s); and iii) one or more unsubstituted oxazolidine(s); and b) 70% to 100% by volume of one or more of components iv)-vii), based on the total volume of the electrolyte solvent: iv) one or more substituted cyclic carbonate(s) having 3-15 carbon atoms: v) one or more substituted lactone(s) having 3-15 carbon atoms; and vi) one or more substituted oxazolidine(s) having 3-15 carbon atoms; and vii) one or more acyclic carbonate(s) having 2-20 carbon atoms. A method of making a cathode and cathodes and batteries made by the methods are also disclosed.
