Template-free synthesis of Na0.95V3O8 nanobelts with improved cycleability as high-rate cathode material for rechargeable lithium ion batteries

Ultra-long Na2V6O16·xH2O nanowires: large-scale synthesis and application in binder-free flexible cathodes for lithium ion batteries

“…Na + ) have been investigated and alternately incorporated into the (V 3 O 8 ) À layers for a larger interlayer distance than that of LiV 3 O 8 to obtain good cyclic stability. [13][14][15] Zhou et al synthesized Na 0.33 V 2 O 5 $1.3H 2 O nanowires using hydrothermal method, based on the reaction of V 2 O 5 and Na 2 HPO 4 $12H 2 O. 16 Yu et al has successfully synthesized Na 2 V 6 O 16 $3H 2 O nanobelts using V 2 O 5 and NaF as raw materials by hydrothermal method without using any templates or catalysts.…”

Effect of crystalline structure on the electrochemical properties of K0.25V2O5 nanobelt for fast Li insertion

“…There is a great interest to increase specific capacity, power density, life span and safety [13][14][15][16][17]. In the last few years, vanadium-based oxides and their derivative compounds have been extensively investigated as cathode materials due to their high specific capacity, large energy density, and low cost [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34].…”

“…Among the potential candidates, copper vanadates and silver vanadium oxides can deliver high initial specific capacity but suffer from irreversible structure change and rapid capacity fade upon cycling [32,33,[35][36][37][38][39]. Lithium trivanadate (LiV3O8) and sodium vanadium oxides can have good structural stability and high specific capacity [19][20][21][22][23][24][25][26][27][28]40]. Na1.1V3O8 shows 95% capacity retention after 200 cycles [28].…”
