Effect of ionic liquid as a flame-retarding additive on the cycling performance and thermal stability of lithium-ion batteries
چکیده انگلیسی

Different ionic liquids based on the 1-butyl-1-methylpyrrolidinium cation are added as a flame-retarding additive to a standard organic electrolyte, and their influences on the cycling performance and thermal stability of lithium-ion cells are investigated. The self-extinguishing time and DSC results demonstrate that the addition of the ionic liquids to the base electrolyte is effective in reducing the flammability of the electrolyte solution and improving the thermal stability of the cell. Among the ionic liquids evaluated in this study, 1-butyl-1-methylpyrrolidinium hexafluorophosphate was the most desirable flame-retarding additive for achieving the best cycling performance of lithium-ion cell.


► Different ionic liquids are added as a flame-retarding additive to base electrolyte.
► Addition of ionic liquid reduces the flammability and improves the thermal stability.
► BMP–PF6 is the best flame-retarding ionic liquid for good cycling performance.
