(EP910874-A1)      A non-aqueous electrolyte for a secondary lithium battery contains solvents, one or more soluble lithium salts other than an lithium polysulphide, and an effective lithium stripping enhancing amount of soluble lithium polysulphide(s) to increase lithium stripping efficiency at the anode-electrolyte interface.    Also claimed are: (1) the above cell with a lithium anode; and (2) the preparation of an electrolyte by combining the active electrolyte with other electrolyte materials selected from porous separator materials, ionically conductive solid polymers and ionically conductive gel polymers.    ADVANTAGE -   Improved cycle life and safety during the first few charge-discharge cycles, and throughout the useful life of the cell. The soluble additive is easily added, and excess amounts of cathode reduction discharge products are prevented from diffusing into the electrolyte. The electrolyte is useful with both lithium metal and lithium ion anodes.
