Electrolytic solvents and applications of such solvents including electric current-producing devices. For example, a solvent can include a sulfone compound of R1—SO2—R2, with R1 being an alkyl group and R2 a partially oxygenated alkyl group, to exhibit high chemical and thermal stability and high oxidation resistance. For another example, a battery can include, between an anode and a cathode, an electrolyte which includes ionic electrolyte salts and a non-aqueous electrolyte solvent which includes a non-symmetrical, non-cyclic sulfone. The sulfone has a formula of R1—SO2—R2, wherein R1 is a linear or branched alkyl or partially or fully fluorinated linear or branched alkyl group having 1 to 7 carbon atoms, and R2 is a linear or branched or partially or fully fluorinated linear or branched oxygen containing alkyl group having 1 to 7 carbon atoms. The electrolyte can include an electrolyte co-solvent and an electrolyte additive for protective layer formation.
电解质溶剂及其应用,包括产生电流的设备。例如,一种溶剂可以包括R1-SO2-R2的磺酰化合物,其中R1是烷基,R2是部分氧化的烷基,表现出高化学和热稳定性以及高氧化抗性。另一个例子是,电池可以在阳极和阴极之间包括电解质,其中包括离子电解质盐和非水电解质溶剂,其中包括非对称、非环状磺酰类。该磺酰类的化学式为R1-SO2-R2,其中R1是具有1至7个碳原子的线性或支链烷基或部分或完全氟化的线性或支链烷基,R2是具有1至7个碳原子的线性或支链或部分或完全氟化的含氧烷基。电解质可以包括电解质共溶剂和电解质添加剂,用于形成保护层。
