Abstract
An electrochemical cell includes a cathode capable of reversibly releasing and receiving an alkali metal; an anode capable of reversibly releasing and receiving the alkali metal; and a non-aqueous electrolyte including one or more dissolved lithium salts, one or more nitriles, sulfur dioxide, and one or more other polar aprotic solvents. In some embodiments, the non-aqueous electrolyte is substantially free of one or more other polar aprotic solvents
