  • CATHODES FOR LITHIUM-SULFUR BATTERIES WITH NANOCATALYSTS
    Publication number: 20240128444
    Abstract: Lithium-sulfur battery cathodes with a graded structure are provided and can include an actively electro-catalyzing and polysulfide-trapping system to improve sulfur utilization and capacity retention, as well as methods of fabricating the same and methods of using the same. The graded structure Li—S cathode can be prepared using economic and scalable synthesis and coating methods.

  • 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.
