  • ELECTROLYTES COMPRISING THIOAMIDES FOR USE IN ELECTROCHEMICAL BATTERIES
    Publication number: 20240113339
    Abstract: Electrolytes for improved electrochemical batteries are provided. A carbonate-based electrolyte can include a thioamide compound (e.g., thioacetamide (TAA), thiourea (THU), or thioformamide). The electrolyte can include a salt, a carbonate solvent, and the thioamide compound as an additive. The thioamide compound can be present in a concentration of, for example, 1 millimolar (mM) to 100 mM.

  • BATTERY COMPRISING A METAL INTERLAYER
    Publication number: 20230006213
    Abstract: Batteries having a metal interlayer that acts as an ion conductor are provided, as well as methods of forming the same. The metal interlayer can include, for example, palladium, platinum, iridium, rhodium, ruthenium, osmium, gold, silver, or a combination thereof, and can act as a conductor while also inhibiting the transport of other species that would produce byproduct films and cause capacity degradation in the battery.
