SYNTHESIS AND CHARACTERIZATION OF LiFSI DERITATIVE CONTAINING FLUOROSULFONYL UREA LITHIUM SALT FOR LI-ION BATTERIES |
| 초록 |
Lithium-ion batteries are a commonly used type of rechargeable battery with the advantages that are high energy density, relatively low self-discharge, low maintenance and high open-circuit voltage. 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 amine and created a urea 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 FSU form was compared by LiPF6. |
