Crystalline Li₃V₆O₁₆ rods as high-capacity anode materials for aqueous rechargeable lithium batteries (ARLB)

Abstract

Li3V6O16 rods are hydrothermally synthesized from aqueous mixtures of LiOAc and V2O5 (autoclave, 200 °C, 48 h), followed by heat treatment at 400 °C.

High‐Energy Aqueous Lithium Batteries

“…For instance, although the formation of solid electrolyte interphase (SEI) is of utmost importance for the cyclability of LIB, the significant role of the electrolyte does not allow to exclusively study the electrochemical behavior of the electrode material under consideration. The current research has specifically targeted the development of ARLBs, but in practice, most of the recent papers have followed the same line of research in investigating a limited range of cathode and anode materials in the same aqueous electrolytes . A possible reason is that the key advantage of ARLBs was low cost, and thus, the focus was limited to a few inexpensive materials (e.g., lithium salts).…”

Reconciled Nanoarchitecture with Overlapped 2 D Anatomy for High‐Energy Hybrid Supercapacitors

“…The signal at a BE of 162.15 eV indicates the existence of low‐coordination sulfur ions at the surface, and the signal at a BE of 163.25 eV indicates metal bonding to sulfur . The V 2p spectrum in Figure D shows two signals at BEs of 513.38V and 520.65 eV, and they can be attributed to the +4 valance state of vanadium . The XPS chemical composition measurements reveal a 1:1.99 atomic ratio of V/S, which is almost identical to the stoichiometric ratio of VS 2 .…”

“…[22] TheV 2p spectrum in Figure 1D shows two signals at BEs of 513.38Va nd 520.65 eV, and they can be attributed to the + 4v alance state of vanadium. [19,23] TheX PS chemical composition measurements reveala1 :1.99 atomic ratio of V/S,w hich is almost identical to the stoichiometric ratio of VS 2 .T he XPS analysis of SG is shown in Figure S2 b, c, and the results indicate the successful introduction of sulfur into the graphene sheets. To examine the percentages of VS 2 and graphene in VS 2 / G, TGA was utilized, as shown in Figure 1E.T he measurements were performed in airf rom room temperature up to 700 8Cw ith ar amp rate of 10 8Cmin À1 .T he results show that VS 2 comprises 90.10 %( wt %) of the material.…”

Design and Fabrication of Novel Sheet-like Iron Vanadate Photocatalyst for the Photoreduction of Chromium

“…Due to its magnetic behavior for easy recycle and high potential performances, Fe 2 V 4 O 13 is expected to be a superior material for the removal of hazardous heavy metal ions into the aquatic environment. Very few efforts have been made to examine lithium-ion batteries, Fenton-like catalyst, photocatalytic reduction CO 2 and degradation gaseous isopropyl alcohol applications of Fe 2 V 4 O 13 nanomaterials [13][14][15][16]. The photocatalytic activity strongly depends on the crystalline nature, specific surface area and surface morphology [17].…”
