  • Flame Retardants For Lithium Batteries
    Publication number: 20220416299
    Abstract: This invention provides nonaqueous electrolyte solutions for lithium batteries which contain one or more brominated flame retardants. The nonaqueous electrolyte solutions comprise i) a liquid electrolyte medium; ii) a lithium-containing salt; and iii) at least one brominated flame retardant. The brominated flame retardant is present in the electrolyte solution in a flame retardant amount, has a boiling point of about 60° C. or higher, and has a bromine content of about 55 wt % or more based on the weight of the brominated flame retardant.
