ELECTROLYTES COMPRISING THIOAMIDES FOR USE IN ELECTROCHEMICAL BATTERIES

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.
