A battery cells that include sulfide cathodes are described with examples being suitable for operation at elevated temperatures. Also described are methods of making and using these battery cells.

Solid state battery system usable at high temperatures and methods of use and manufacture thereof

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.

Auxiliary electrode mediated membrane-free redox electrochemical cell for energy storage

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.
