Characterization of vanadium oxide sol as a starting material for high rate intercalation cathodes

Using an Atmospheric Pressure Chemical Vapor Deposition Process for the Development of V2O5 as an Electrochromic Material

“…Additionally, it is well known that the Li + intercalation/deintercalation response is dependent on the diffusion coefficient of the species; consequently, a large diffusion coefficient will result in a fast response [40]. The diffusion coefficient of APCVD V2O5 estimated in this work is higher than V2O5 grown by atomic layer CVD [41], solution process [42], spin-coating [43], and pulsed spray pyrolysis [44], strengthening the growth of large area electrodes by APCVD with good electrochemical performance. …”

Electrospun porous vanadium pentoxide nanotubes as a high-performance cathode material for lithium-ion batteries

“…In addition, V 2 O 5 has advantages of low cost, abundance and better safety, which make it a promising cathode candidate. However, the practical application of V 2 O 5 has been seriously hindered by the slow lithium-ion diffusion, low electronic conductivity, which leads to poor cycling stability and poor rate capability [6][7][8]. To improve electrochemical performance of the V 2 O 5 electrode, fabricating nanostructured V 2 O 5 materials such as nanofibers [9], nanowires [10] and nanospheres [11][12][13] has become one of the most effective methods to enhance the electrochemical performance due to the improved lithium-ion diffusion and electronic conductivity.…”

High Pseudocapacitance from Ultrathin V2O5Films Electrodeposited on Self‐Standing Carbon‐Nanofiber Paper

“…[ 24,25 ] The effects of thin V 2 O 5 layers on conductive materials such as metal fi bers and carbonaceous materials have been studied recently. [26][27][28][29][30] The issue at hand is how to design the electrode structure with a metal oxide rather than choose the oxide material, since most metal oxides provide more-or-less similar pseudocapacitance. Metal oxides have a high resistivity, which is detrimental for high-power capacitance and cycle performance.…”
