High voltage electrolyte for Lithium Battery/Super Capacitor
 
Research of ionic liquids for high voltage electrolyte used in the lithium battery and super capacitor has been developed, because of the wide electrochemical windows and the designed structrue. A series of 4.9V electrolyte with ionic liquids as additive for LNMO battery have been investigated, which improve the cyclic performances. A series of 4.35Velectrolyte with ionic liquids as additive for LCO battery have been investigated, which can improve the cyclic performance of LCO battery. The energy density of super capacitor can be increased to 1.32 times than that of traditional electrolytes, by enhancing the voltage from 2.7V to 3.1V. The production plant in large scale has been established and the ionic liquids additive has won high praise at domestic and abroad (Fig. 5). Scientific and technological achievement appraisal of Research of New Type of Ionic Liquids Electrolyte for Lithium battery was obtained in the Chinese Academy of Sciences at the end of 2013, which reached the international leading level.
