Abstract: The present invention relates generally to the field of nonaqueous electrolyltes for use in electric current producing cells. More particularly, the present invention pertains to nonaqueous electrolytes comprising a highly concentrated solution of one or more lithium salts in one or more nonaqueous solvents. More specifically, the present invention pertains to nonaqueous electrolytes, suitable for use in an electric current producing cell, comprising: (a) one or more lithium salts, dissolved in (b) one or more nonaqueous oxygen-containing solvents; wherein the concentration of said one or more lithium salts is: (i) greater than 110 % of the molar concentration of said one or more lithium salts which would provide maximum ionic conductivity at 25 DEG C in said one or more solvents; and, (ii) greater than 1.3 M. The present invention also pertains to electric current producing cells comprising such nonaqueous electrolytes, and methods for increasing the safety and cycle life of an electric current producing cell.
