“…By an analogous procedure enlarged by addition of acetylene black, composite V 2 O 5 /C can be synthesised. There exist the literature data that in organic electrolyte solutions, both lithium and manganese ions may be reversibly intercalated into V 2 O 5 /C composite at an acceptably high rate [11,16,17]. However, similar examinations in aqueous solutions were not published thus far.…”

We synthesized both the V 2 O 5 xerogel and the composite V 2 O 5 xerogel/C starting from the solution of V 2 O 5 in hydrogen peroxide. After the characterization by XRD, thermal (TGA-DTA), SEM methods and by particle size analysis, the investigation of Li + and Mg 2+ intercalation/deintercalation reactions in an aqueous solutions of LiNO 3 and Mg(NO 3 ) 2 were performed by cyclic voltammetry. The composite material V 2 O 5 xerogel/C displayed relatively high intercalation capacity, amounting to 123 mA h g −1 and 107 mA h g −1 , in lithium and magnesium salt solutions, respectively.

“…40 Imamura et al further studied the structural evolution upon magnesiation/demagnesiation process through x-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR) techniques, which clearly identifi ed the intercalation of Mg 2+ ion in the layered structure. 41 Recent work by Aurbach's group on V 2 O 5 significantly advanced our understanding of this cathode material in Mg battery system. 42 They systematically investigated the morphology and structural change of V 2 O 5 thin fi lm in the three-electrode cell using 0.1 M Magnesium bis(trifluoromethanesulfonyl) imide/acetonitrile (Mg(TFSI) 2 /CAN) or 0.5 M Mg(ClO 4 ) 2 /ACN as electrolyte and carbon paper as counter electrode.…”

Current performance of Mg battery cathode is reviewed. Perspective for research in this fi eld is provided and discussed.Mg battery has recently gathered more and more interest as a high energy density replacement of current Li-ion battery. Signifi cant progress has been made in developing sustainable anode and novel electrolyte. However, the success of Mg battery still high demands the search of cathode material with high energy density, good rate capability, and nice cyclability. This current review focuses on the development of Mg battery cathode in the past 15 years. A detailed review about the performance and limitations of reported cathode material is provided.A perspective for this area is discussed with insights for future research direction. Three important areas that must be explored in this fi eld in near future are suggested: the investigation of high capacity cathode, the study of hybrid ion battery, and deeper understanding about the magnesiation chemistry of the cathode.

“…This material provides a high surface area with plenty of hydrophilic moieties on its surface, and is electrically well-networked such that the adsorbed polysulfide can be easily further reduced or oxidized on its surface [25][26][27].…”

The effect of V2O5/C additive on the suppression of polysulfide dissolution in Li-sulfur batteries

The effect of adding a V 2 O 5 /carbon nanocomposite to the cathode of a Li-sulfur battery on suppressing the polysulfide dissolution phenomenon was evaluated by comparing the amount of overcharge at the first dischargecharge processes. V 2 O 5 /carbon nano-composite was manufactured by forming V 2 O 5 ⋅H 2 O xerogel on the carbon black through a simple wet process. This provides a high surface area with plenty of hydrophilic moieties that can capture and store soluble polysulfides on its surface during the discharge-charge reactions, and also partly contributes to suppressing the excessive formation of Li 2 S which undergoes a large volume change during the cycling. From the electrochemical results, we could observe a significant reduction in the overcharge amount and improved cyclic performance by adding as little as 2 % of the nano-composite. UV-VIS spectra measured after a small addition of the nano-composite to the solution containing Li 2 S 6 polysulfide also confirmed that the V 2 O 5 /carbon nano-composite is highly effective in capturing long-chain polysulfides on its surface.
