Synthesis and Characterization of Novel Ionic Liquids: Pyrrolinium with Alkoxy Substituents as Electrolytes for Lithium Ion Battery |
| 초록 |
Lithium ion batteries (LIBs) have some advantages such as a high energy density, negligible memory effect, high open circuit voltage and a less self-discharge. Although LIBs have been considered to be promising rechargeable power sources for next-generation HEVs, the safety issue of LIBs, especially electrolyte such as carbonate, must be found a solution to realize large, high-power, and high-voltage LIBs. The highly flammable carbonate type solvents that are used in common liquid electrolytes can be major causes of fire and explosion. Thus, ionic liquids (ILs) have attracted much attention due to their superior thermal stability. Due to the ionic nature in bonding, ILs show unique properties such as high ionic conductivity and high thermal stability. In the present work, novel pyrrolinium-based ILs were studied as electrolytes for LIBs to overcome safety problem and improve electrochemical stability. |
