▎ 摘　　要

NOVELTY - A rechargeable lithium cell comprises (a) cathode having a cathode active material and a first electrolyte in ionic contact with the cathode active material; (b) anode having an anode current collector but no anode active material and having no lithium metal when the cell is made; (c) a porous separator electronically separating the anode and cathode; and (d) a second electrolyte comprising a polymer electrolyte in ionic contact with the first electrolyte, where the polymer electrolyte is disposed between the anode and cathode, between the separator and cathode, and/or between the separator and anode. USE - A rechargeable lithium cell e.g., lithium metal secondary cell, a lithium-ion cell, a lithium-sulfur cell, a lithium-ion sulfur cell, a lithium-selenium cell, or a lithium-air cell (all claimed) for battery-powered electric vehicles. ADVANTAGE - The rechargeable lithium cell provides a safe, non-flammable, quasi-electrolyte electrolyte system for a rechargeable lithium cell that is compatible with existing battery production facilities. The electrolyte must be sufficiently high in lithium salt concentration to ensure non-flammability and yet also maintain adequate flowability (fluidity) to enable injection of liquid electrolyte into dry battery cells. The battery exhibits a high energy density, high power density, long cycle life, and no danger of explosion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for producing the rechargeable lithium cell which involves (A) preparing a lithium cell comprising (i) a cathode having a cathode active material and a first electrolyte in ionic contact with the cathode active material, (ii) an anode having an anode current collector but no anode active material and having no lithium metal when the cell is made, (iii) an optional porous separator or ion-permeable membrane electronically separating the anode and cathode, and (iv) a protecting housing that encloses the cathode, the anode, the optional separator, where lithium cell has an unfilled space; and (B) introducing a second electrolyte into unfilled space, where the second electrolyte comprises a polymer electrolyte in ionic contact with first electrolyte and being disposed between the anode and the cathode, between the separator and the cathode, and/or between the separator and the anode.
