Abstract
(EN)
Improved battery systems have been developed for lithium-ion based batteries. The improved systems include a nonaqueous electrolyte including one or more lithium salts, one or more nonaqueous solvents, and an additive or additive mixture comprising one or more operative additives selected from a group of disclosed compounds, including 3-aryl substituted 1,4,2- dioxazol-5-ones and 3-phenyl-1,3,2,4-dioxathiazole 2-oxide.
