1. A rechargeable lithium battery device comprising:

  • an anode current collector comprising a metal material selected from copper, nickel, chrome ferrous alloy, a refractory metal, or stainless steel, the metal material being substantially inert toward a lithium metal material;

    an anode overlaying the anode current collector, and the anode being electrically coupled to the current collector and comprising lithium metal material;

    a first electrolyte layer overlaying the anode consisting of Li2S, Li2O, or combinations thereof, the first electrolyte layer being substantially stable toward lithium metal material, the first electrolyte layer being characterized by a first deposition rate and a thickness of 10-100 nm;

    a second electrolyte layer in direct contact with the first electrolyte layer and comprising at least one of lithium nitride, lithium fluoride, or lithium aluminum fluoride, the second electrolyte layer being characterized by a second deposition rate;

    a cathode overlaying the second electrolyte layer; and

    a cathode current collector overlaying the cathode;

    wherein the first electrolyte layer and the second electrolyte layer are characterized by a total thickness of less than 20 um.
