(WO9515015-A1)      A multilayered electrolyte (56), for use in an electrochemical cell, comprises: (a) a primary electrolyte layer (58) comprising a polymer substrate impregnated with an active ingredient; and (b) a secondary electrolyte (60a, 60b), disposed on the side(s) of the primary electrolyte layer (58), fabricated of a material different to that of the primary electrolyte.    Also claimed is a lithium polymer electrochemical cell comprising: (i) a lithium contg. negative electrode (52); (ii) a positive electrode (54) fabricated of a material having high electrode potential versus lithium; and (iii) a multilayered electrolyte, as above, disposed between the positive and negative electrodes.    USE -   The electrolyte is used in rechargeable electrochemical battery cells for applications such as radio communication, satellites, portable computers, electric vehicles, etc.    ADVANTAGE -   Has enhanced conductivity, yet reduces the occurrence of deleterious reactions taking place at the negative and positive electrode/electrolyte interfaces.
