Abstract: A sulfur cathode generated at least in part by in situ electrochemical pulverization of a metallic sulfide compound is provided. The in situ generated sulfur cathode suppresses the unfavorable process of polysulfide shuttling to provide enhanced sulfur cathode performance and is envisioned for use in Li—S, Na—S, K—S, Ca—S, Mg—S or Al—S batteries used to support rechargeable electronic devices and electric vehicles.

Abstract: The invention provides a membrane-free redox cell utilizing auxiliary electrodes that facilitate fast charging and discharging of anolyte and catholyte for electrochemical energy storage. The anode and cathode chambers are ionically separated, and electrically connected through a conductor joining auxiliary electrodes comprised of a redox material. In use, charging/discharging of the galvanic cell takes place between primary electrodes, and the redox material is immersed in the electrolyte in both anode and cathode chambers.

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.

Abstract: Disclosed herein is a re-chargeable Li-air battery cell comprising a Li-based garnet-type Li6.5La2.5Ba0.5ZrTaO12 (LLBZT) electrolyte and the like. The Li-rich LLBZT is adjacent to a ceramic wall which, in turn, is adjacent to a porous or dense cathode which, in turn, is adjacent to a porous or dense current-collecting layer. Two or more re-chargeable Li-air battery cells comprising LLBZT may be connected in series. The barium component of the LLBZT may be substituted or doped with an alkaline rare earth metal, for example one of beryllium, magnesium, calcium, strontium, and radium. The tantalum component of LLBZT may be substituted or doped with niobium or lanthanum.

Abstract: Solid-state, ion-conducting batteries with an ion-conducting, solid-state electrolyte. The solid-state electrolyte has at least one porous region (e.g., porous layer) and a dense region (e.g., dense layer). The batteries are, for example, lithium-ion, sodium-ion, or magnesium-ion conducting solid-state batteries. The ion-conducting, solid-state electrolyte is, for example, a lithium-garnet material.
