Journal ArticleDOI
Transport coefficients, Raman spectroscopy, and computer simulation of lithium salt solutions in an ionic liquid
Marcelo José Monteiro,Fernanda Ferraz Camilo Bazito,Leonardo J. A. Siqueira,Mauro C. C. Ribeiro,Roberto M. Torresi +4 more
TL;DR: Molecular dynamics simulations showed that the coordination of Li+ by oxygen atoms of TFSI anions changes with Li+ concentration producing a remarkable change of the RTIL structure with a concomitant reduction of diffusion coefficients of all species in the solutions.
Journal ArticleDOI
Electrode passivation caused by polymerization of different phenolic compounds
TL;DR: An electrochemical quartz crystal microbalance was used to investigate the formation of polymeric products resulting from electrooxidation in aqueous solutions of phenolic compounds on the surface of Au and Pt electrodes as discussed by the authors.
Journal ArticleDOI
Accelerating rate calorimetry studies of the reactions between ionic liquids and charged lithium ion battery electrode materials
Yadong Wang,Karim Zaghib,Abdelbast Guerfi,Fernanda Ferraz Camilo Bazito,Roberto M. Torresi,J. R. Dahn +5 more
TL;DR: In this article, the authors used accelerating rate calorimetry (ARC) to compare the reactivity of six ionic liquids (with and without added LiPF6) and charged electrode materials.
Journal ArticleDOI
Calibration of the Electrochemical Quartz Crystal Microbalance
TL;DR: In this article, the average sensitivity of the quartz crystal microbalance was calculated for the case of localized mass perturbation, where the mass change is continuously but nonuniformly distributed across the surface.
Journal ArticleDOI
Synthesis and characterization of two ionic liquids with emphasis on their chemical stability towards metallic lithium
TL;DR: Two room temperature ionic liquids (RTILs) without acidic protons, based on different cationic species (BMMI) and N - n -butyl- N -methylpiperidinium (BMP) using (CF 3 SO 2 ) 2 N − (TFSI) as anion, were prepared by quaternization of their respective amines with an appropriate alkyl halide, followed by ion exchange reaction as mentioned in this paper.
