Novel pyrrolinium-based ionic liquids with an allyl substituent as electrolytes for lithium secondary batteries |
초록 |
Ionic liquids (ILs) are salts existing in liquid at room temperature even if they are composed of ionic species, cations and anions. Due to the ionic nature in bonding, they show unique properties such as high ionic conductivity and high thermal stability. In the present work, pyrrolinium-TFSI ILs having an allyl substituent have both higher decomposition temperature and wider electrochemical windows than the carbonate electrolytes. [A(OEt)]Pyrl-TFSI with both an ethoxy and an allyl substituent showed the lowest viscosity among them. These results seem to indicate that the allyl substituent together with the ethoxy group have some positive effects on its physicochemical and electrochemical properties. |
