| 1 | A highly concentrated vanadium protic ionic liquid electrolyte for the vanadium redox flow battery显示文摘A protic ionic liquid is designed and implemented for the first time as a solvent for a high energy density vanadium redox flow battery.Despite being less conductive than standa rd aqueous electrolytes,it is thermally stable on a 100 ℃ temperature window,chemically stable for at least 60 days,equally viscous and dense with typical aqueous solvents and most importantly able to solubilize to 6 mol L^(-1) vanadium sulfate,thus increasing the VRFB energy density by a factor of 2.5.Electrochemical measurements revealed quasi-reversible redox transitions for both catholyte and anolyte at 25 ℃ while a proof-of-concept redox flow cell with the proposed electrolyte was tested for a total of 150 cycles at 25 ℃,showing an open circuit potential of 1.39 V and energy and coulombic efficiencies of 65% and 93%,respectively.What’s more,the battery can be equally cycled at 45℃ showing good thermal stability.This study underlines a new route to improve the energy-to-volume ratio of energy storage system. | Georgios Nikiforidis Amal Belhcen Mérièm Anouti | 2021 | Journal of Energy Chemistry2021，30，6： | 4 |
| 2 | Protic ionic liquids/poly(vinylidene fluoride) composite membranes for fuel cell application显示文摘Poly(vinylidene fluoride), PVDF, membranes have attracted considerable attention as polymer electrolytes for fuel cells. This study explores the effect of solvent on the spherulite size and the crystallinity of the polymeric membranes. Based on Hansen solubility parameters theory, the mixture of DMC and DMSO was selected among a dozen of solvents for the preparation of PVDF membranes by thermally induced phase separation. The addition of two protic ionic liquids(PILs), bis(2-ethyl hexyl) ammonium hydrogen phosphate [EHNH_2][H_2PO_4], and imidazolium hexanoate [Im][Hex] to PVDF membranes at concentrations(10% < wP IL< 50%) has been investigated by SEM, FTIR, DSC, TGA, EIS, and DMA. The inclusion of ionic liquids into the polymer matrix influences structural parameters(degree of crystallinity and electroactive phases), thermal stability, proton conductivity and mechanical properties of the membranes. The membranes become transparent regardless type of ionic liquid employed. A small amount of ionic liquids increases the degree of crystallinity and facilitates the production of polar β and γ crystals. The proton conductivity mechanism(Grotthuss) is dependent on the ionic liquid structure(due to its selforganization in water) and the content in the PVDF membrane, as well as the membrane water uptake.Different behavior has been observed for the two ionic liquids, which stresses the challenge on selecting an appropriate cation and anion combination. The obtained composite membranes exhibited excellent mechanical performance and reduced elastic modulus, with respect to the pure polymer matrix. These results indicate that PVDF/IL composite membranes have a high potential for PEMFC applications. | Isabel Vazquez-Fernandez Mohamed Raghibi Adnane Bouzina Laure Timperman Janick Bigarre Meriem Anouti | 2021 | Journal of Energy Chemistry2021，30，2： | 3 |
| 3 | Effect of cation(Li^+, Na^+, K^+, Rb^+, Cs^+) in aqueous electrolyte on the electrochemical redox of Prussian blue analogue(PBA) cathodes显示文摘Prussian blue analogue(PBA)material is a promising cathode for applications in Na-ion and K-ion batteries which can support high c-rates for charge and discharge.In this study,the material of composition[K2 CuIIFeII(CN)6]was synthesized and its structural and electrochemical redox behavior was investigated with 5 different alkali insertion cations(Li^+,Na^+,K^+,Rb^+,Cs^+).Galvanostatic measurements indicate that the redox potential strongly depends on the ionic radius of the inserted cation.The redox potential varies by 400 m V between using Li^+(0.79A)or Cs^+(1.73A)in the electrolyte.The underlying modification of the Fe2^+/Fe3^+redox potential in PBA is proposed to be due to the weakening of the Fe–C bond in the material.This hypothesis is supported by XRD measurements which reveal that the lattice parameter of the de-intercalated host structure follows the same trend of monotonic increase with the cation size.The relatively minor volume changes accompanying the redox(1.2%–2.4%)allow the PBA to accommodate differently sized cations,although the structural hindrances are quite pronounced at high c-rates for the larger ones(Rb^+and Cs^+).Cycle aging studies indicate that the minimum capacity fade rate is observed in case of K^+ and Rb^+ containing electrolyte.The peak intensity corresponding to the[220]crystallographic plane varies depending on the state of charge of PBA,since this plane contains the insertion cations.Owing to the sensitivity of the redox potential to the insertion cation coupled with the observed fast ion-exchange ability,the PBA material may find additional analytical applications such as ion sensing or filtration devices. | Satyajit Phadke Roman Mysyk Meriem Anouti | 2020 | Journal of Energy Chemistry2020，29，1： | 2 |

| 12 | Effect of fluorinated additives or co-solvent on performances of graphite//LiMn2O4 cells cycled at high potential显示文摘Herein,a comprehensive study of electrochemical performances of the combined effect of fluorinated additives;fluoroethylene carbonate(FEC);and tris(2,2,2-trifluoroethyl) phosphite(TTFP) or the 2,2,2-trifluoroethyl methyl carbonate(TFEMC) as co-solvent,on Graphite//LiMn2O4 cells cycled at high potential is reported.On one side,each additive has a specific function,the FEC is dedicated to the negative electrode and the TTFP to the opposite one.The electrolyte mixture with(4% FEC+1% TTFP) additive has shown the best ability to reduce fading of the LiMn2O4 electrode,especially at high rates.On the other side,by studying the comparative thermal and transport properties of the formulated electrolytes with different proportions of TFEMC,we demonstrate that the difference in charge distribution of EMC and TFEMC molecules induced by the presence of fluorine atoms,modifies the solvation model of the Li+cation,and changes its behavior at the CEI interface and impact strongly the electrochemical performances.Finally,the EIS investigation of the LMO/electrolyte interfaces in the presence of TFEMC demonstrates that despite a spontaneous chemical reactivity of the TFEMC at the cathode interface over time,the conductive and good quality CEI is formed,which positively impact the cyclability.This study shows that against LMO surface phenomena,the combination in adequate proportions of fluorinated additives or solvent can be a solution not only to avoid the oxidative reactivity of LMO-cathode,but also to prevent its harmful consequences on the Li-metal or graphite-anode by controlling the solvation of lithium-ion. | Benjamin Flamme Darius JYeadon Satyajit Phadke Mérièm Anouti | 2021 | Journal of Energy Chemistry2021，30，1： | 1 |
