Synthesis and electrochemical properties of LiV3O8 phase

Improvement in electrochemical performance of V2O5 by Cu doping

“…Vanadium based oxides such as V 2 O 5 , LiV 3 O 8 , V 6 O 13, and some transitional metal vanadates (MeV 2 O 6 ) have been considered as cathode materials for rechargeable lithium batteries because of their high energy densities, low price and good safety properties [1][2][3][4][5][6][7][8][9]. Among these vanadium oxides, V 2 O 5 has gained the most attention for more than two decades [10].…”

Influence of pH and ionic strength on vanadium(v) oxides formation. From V2O5·nH2O gels to crystalline NaV3O8·1.5H2O

“…Vanadium oxide based materials have been extensively studied for their electronic and ionic properties. [1][2][3][4][5][6][7] Some of them appear to be promising candidates as reversible cathodes in lithium batteries but their properties strongly depend on their structural features. [8][9][10][11] For instance, the low-temperature form of Li x V 3 O 8 is able to accommodate 4.5 mol of Li + ions per formula unit, instead of 3 mol for the high temperature trivanadate.…”

A new low-temperature synthesis and electrochemical properties of LiV3O8 hydrate as cathode material for lithium-ion batteries

“…It is known that a low degree of crystallinity of LiV 3 O 8 enhances the electrochemical performance of LiV 3 O 8 [17][18][19]. The enhanced cycle stability of our materials attributes to the enlarged inter-plane spacing that provides larger interstitial and good channels for lithium transfer and diffusion [14]. The 200 • C products show similar phase structural behavior, which account for the similar discharging performance of the 200 • C products.…”

“…precursors followed by heating. Liu et al [14] prepared LiV 3 O 8 from V 2 O 5 and LiOH in their aqueous solution by heating at 480 • C for 10-12 h, and obtained an initial discharge capacity of 258 mAh g −1 measured at a low current density of 0.3 mA cm −2 . Guyomard and co-workers [8] prepared LiV 3 O 8 from V 2 O 5 and Li 2 CO 3 by sol-gel method and heated at 650 • C for 10 h. The products show an initial discharge capacity of 210 mAh g −1 at ∼90 mA g −1 current density.…”

“…The cyclic stabilities of their materials decrease with the increasing of cycling. These studies involve heating of the reactants at a higher temperatures, between 300-600 • C [8,14]. It is known that the crystallinity of the phase has large effects on the electrochemical performance of LiV 3 O 8 [5].…”
