SYNTHESIS AND CHARACTERIZATION OF LiFSI DERITATIVE CONTAINING FLUOROSULFONYL ESTER LITHIUM SALT FOR LI-ION BATTERIES |
| 초록 |
Lithium-ion batteries have gained an unprecedented importance in the energy storage of portable devices such as cell phone, and tablet personal computer in the last several years. Our purpose in the present work is to synthesize a new electrolyte based on fluorosulfonyl isocyanate that can be used in lithium-ion battery. The most popular subject Lithium bis(fluorosulfonyl)imide (LiFSI) electrolyte salt has a thermal stability and a high ionic conductivity. We synthesized a new type of electrolyte having a functional group of fluorosulfonyl imide like LiFSI that can more effectively provide lithium ions. Isocyanate was reacted with allyl alcohol and created a ester form which can make the structure to increase further portion of lithium ions. The resulting electrolytes were characterized by FTIR, 1H NMR spectroscopy and thermogravimetric analysis (TGA). The ionic conductivity of FSE form was compared by LiPF6. |
