| 제목 | Binary Mixture of Carbonate and Ionic Liquids as Electrolyte for Lithium Ion Battery |
| 초록 | Lithium ion batteries (LIBs) have been researched to apply large-scale devices such as electric vehicles or energy storage systems. However, LIBs must overcome safety issues in explosion caused by flammable carbonate electrolytes. In this regard, ionic liquids (ILs) could be candidates as alternative electrolyte due to their non-flammable and non-volatile properties. To obtain the advantages of each electrolyte of ionic liquid and carbonate, we propose a mixed system of ILs and commercial carbonate. Herein, we analyze the physicochemical properties of binary electrolytes while differentiate the ratio between prepared ILs and carbonates. In thermal behavior, we make certain that the higher ratio of the ILs have a positive effect on the thermal stability. Furthermore, the 6:4 ratio (ILs:carbonate) of mixed electrolyte shows better properties than the other mixed system in electrochemical and physicochemical characteristics. |
