چکیده
The formation potentials of solid-electrolyte interphase (SEI) were investigated in 1-butyl-1-methylpyrrolidinium bis(fluorosulfonyl)amide (BMPFSA) and bis(trifluoromethylsulfonyl)amide (BMPTFSA) containing LiFSA LiTFSA, respectively, by monitoring the redox reaction ferrocene with high sensitivity. SEI was found to affect electrode kinetics outersphere electron transfer reaction. SEIs thickness less than a few nm formed LiFSA/BMPFSA LiTFSA/BMPTFSA at 2.4 2.5 V vs Li?Li(I), respectively. cathodic decomposition FSA – TFSA considered be promoted interaction Li + based on ab-initio calculation.

Electrolyte and Solid-Electrolyte Interphase Layer in Lithium-Ion Batteries
The supply and the management of the energy are particularly at the centre of our daily concerns and represent a socio-economic priority. Indeed, while cars use fossil fuel as the main source of energy for over a century, the depletion of the oil reserves and the necessity to reduce the carbon dioxide emissions, stimulate the development of electric vehicles. Therefore, one of the main challeng...

Aiming at an improved knowledge of the formation of the solid electrolyte interphase (SEI), as basis for the safe and efficient use of new anode materials, we investigated the SEI formation on silicon and lithium titanate (LTO) anodes by electrochemical impedance spectroscopy (EIS) and ex situ X-ray photoelectron spectroscopy (XPS) measurements. While the EIS measurements performed at equidista...

Aqueous lithium energy storage systems address environmental sustainability and safety issues. However, significant capacity fading after repeated cycles of charge-discharge and during float charge limit their practical application compared to their nonaqueous counterparts. We introduce an artificial solid electrolyte interphase (SEI) to the aqueous systems and report the use of graphene films ...

The decomposition of ethylene carbonate (EC) during the initial growth of solid-electrolyte interphase (SEI) films at the solvent-graphitic anode interface is critical to lithium ion battery operations. Ab initio molecular dynamics simulations of explicit liquid EC/graphite interfaces are conducted to study these electrochemical reactions. We show that carbon edge terminations are crucial at th...
