Doped Vanadium Oxides as Host Materials for Lithium Intercalation

Abstract: Doped vanadium pentoxides with a doping ratio M/V (M = Ag and Cu) ranging from 0.01 to 0.5 were synthesized. With the successful doping, the electronic conductivity of V2O5 was increased by two to three orders of magnitude. The electrochemical performance of the doped materials is very high. Up to 4 moles of lithium per mole of doped V2O5 were found to be reversibly intercalated. The composite cathodes containing the doped materials also showed very high intercalation rate performance. In addition, copper‐… Show more

“…However, the development of rechargeable lithium batteries with V2O5 as a cathode material has been limited due to its poor structural stability, low electronic and ionic conductivity, and slow electrochemical kinetics [14,15]. It is well known that the structure and morphology of V2O5 can strongly influence its electrochemical performance.…”

“…V 2 O 5 matrix has been widely studied due to its properties, such as being an important semiconductor whose electronic conductivity is associated to the electronic jump between V 5+ and V 4+ ions. 1 V 2 O 5 xerogels have been used as host materials for several metal cations 2 and they are also studied as cathodes for secondary lithium batteries. 3,4 The lamellar structure allows Li + intercalation/deintercalation during the reduction/ oxidation of vanadium cations.…”

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Layerstructured vanadium pentoxide is one of the most studied vanadium oxides despite its low discharge voltages, low electric conductivity, and slow diffusion kinetics of lithium ions. [6][7][8][9][10][11][12][13] In order to improve the performance of lithium batteries by employing vanadium pentoxide as a cathode material, a few methods have been used to prepare vanadium pentoxide with better characteristics, which includes the use of aerogels, xerogels, nanocomposites of LiV 2 O 5 with electronically conducting organic polymers and nanostructured materials. [9][10][11][12] There have been a few recent attempts to develop synthetic methods for nanomaterials of vanadium oxides but preparation of single-crystal vanadate nanostructures still remains challenging.…”
