A new chemical route for the synthesis of β′-Li V2O5 for use as a high performance cathode

V2O5-P2O5-Fe2O3-Li2O Glass-Ceramics as High-Capacity Cathode for Lithium-Ion Batteries

“…Similar results had been reported when β′-Li x V 2 O 5 particles were coated with an amorphous vanadium oxysulfide film [3]. First, it is related to existence of the amorphous phase in the crystal interface.…”

“…3. On the other hand, the Li x V 2 O 5 glass-ceramics sample have plateau voltages and the related charge-discharge voltage curves are similar to those of Li x V 2 O 5 [3,16]. From the diffraction patterns, point (a) was amorphous and point (b) was a crystal.…”

“…Vanadium based materials such as V 2 O 5 , LiV 3 O 8 , and Li x V 2 O 5 has been extensively studied as a cathode for Li-ion batteries [1][2][3]. Their open structure combined with wide range of oxidation states for vanadium, which range from V 5+ to V 2+ , allows for a high theoretical specific capacity.…”

Electrochemical Properties of Na0.66V4O10 Nanostructures as Cathode Material in Rechargeable Batteries for Energy Storage Applications

“…It has been reported that depending upon the Li + /Na + intercalation amount, V 2 O 5 can yield high discharge capacities [44,45]. In Li-ion batteries, Li x V 2 O 5 is explored extensively [46][47][48][49], but it suffers significant capacity loss dur-ing repetitive charging/discharging for an intercalated amount of x >1 [45]. Analogous to Li x V 2 O 5 in Li-ion, Na x V 2 O 5 was also proposed for Na-ion battery, where the Na cations can be reversibly cycled along the b axis in a similar manner as the Li counterpart.…”

“…Among the vanadium-based oxides, V 2 O 5 has been studied extensively − and the formed bronze tunneled structure is not only more stable compared to the layered structures, but also provide fast ion reaction kinetics. It has been reported that depending upon the Li + /Na + intercalation amount, V 2 O 5 can yield high discharge capacity, i.e., 442 mAh g –1 for 3 Li + per formula. , Furthermore, Li x V 2 O 5 (Li-bronze) has been explored − for Li-ion batteries, but it suffers significant capacity loss during repetitive charging/discharging for an intercalated amount of x > 1 . Analogous to Li x V 2 O 5 in Li ion, Na x V 2 O 5 (Na bronze) was also proposed for Na-ion battery, where the Na cations can be reversibly cycled along the b axis in a similar manner to the Li counterpart.…”
