Khan Inayat Ali, Ion Transport and Electrochemical Properties of Fluorine-Free Lithium-Ion Battery Electrolytes Derived from Biomass / Inayat Ali Khan, O. I. Gnezdilov, A. Filippov, and Faiz Ullah Shah// ACS Sustainable Chem. Eng. - 2021. -N. 9. - P. 7769−7780. |

Unlike conventional electrolytes, ionic liquid (IL)-based electrolytes
o ff er higher thermal stabil ity, acceptab le ionic c onductivit y, and a higher electrochemical stability window (ESW), which are indispensable for the proper functioning of Li-ion batteries. In this study, fl uorine-free electrolytes are prepared by mixing the lithium furan-2-carboxylate [Li(FuA)] salt with the tetra(n -butyl)-phosphonium furan-2-carboxylate [(P4444)(FuA)] IL in diff erent molar ratios. The anion of these electrolytes is produced from biomass and agricultural waste on a large scale and, therefore, this study is a step ahead toward the development of renewable
electrolytes for batteries. The electrolytes are found to have T onset higher than 568 K and acceptable ionic conductivities in a wide temperature range. The pulsed field gradient nuclear magnetic resonance (PFG-NMR) analysis has con firmed that the
(FuA)− anion di ff uses faster than the (P 4444)+ cation in the neat (P 4444)(FuA) IL; however, the anion diff usion becomes slower than cation di ffusion by doping Li salt. The Li + ion interacts strongly with the carboxylate functionality in the (FuA)− anion and diff uses slower than other ions over the whole studied temperature range. The interaction of the Li+ ion with the carboxylate group is also confi rmed by 7 Li NMR and
Fourier transform infrared (FTIR) spectroscopy. The transference number of the Li+ ion is increased with increasing Li salt
concentration. Linear sweep voltammetry (LSV) suggests lithium underpotential deposition and bulk reduction at temperatures
above 313 K. |
