    Abstract: The present invention provides an anode composition comprising (i) a core material (10) comprising a microparticle; (ii) a lithium alloy of said microparticle (14) on a surface of said core material (10); and (iii) a solid electrolyte interface ( "SEP) comprising (a) a LiF and (b) a polymer. The microparticle comprises Si, Al, Bi, Sn, Zn, or a mixture thereof. The present invention also relates to an electrolyte comprising a high lithium fluoride salt concentration in a low reduction potential solvent that is used produce the solid electrolyte interface comprising LiF and a polymer. The anode composition of the invention has an initial coulombic efficiency of at least 90%, a cycling coulombic efficiency of at least 99%, or both.

    Abstract: Disclosed is a method of fabricating a battery or battery component having a solid state electrolyte. A scaffold is provided, the scaffold comprising: a dense central layer comprising a dense electrolyte material, the dense central layer having a first surface, and a second surface opposite the first surface; a first porous layer comprising a first porous electrolyte material, the first porous layer disposed on the first surface of the dense central layer, the porous electrolyte material having a first network of pores therein; wherein each of the dense electrolyte material and the first porous electrolyte material are independently selected from garnet materials. Carbon is infiltrated into the first porous layer. Sulfur is also infiltrated into the first porous layer. The battery component may be used in a variety of battery configurations.
