Abstract

In lithium-ion batteries (LiBs), electrolyte plays an essential role in leading the performance of the cell. Room-temperature (RT) ionic liquids (ILs) are currently the utmost attractive research in the area of LiBs, owing to their intrinsic properties, like low volatility, non-flammability, good thermal stability, and electrochemically stable. In this present study, we report the electrochemical characterization of neat organic, neat ILs, and mixture of organic-ILs (1-Methyl-1-propylpyrrolidinum Bis (Trifluoromethanesulfonyl) Imide (MPPY+TFSI-)). An extensive molarity range has been examined to identify lithium transference numbers (LI-T) associated with symmetrical Li | electrolyte | Li cell. The safety test was performed using symmetrical Li | electrolyte | Li cell for prepared electrolytes.
