Abstract
The electrochemical behavior of V2O5·0.6H2O nanoribbons in 0.5mol/L Li2SO4, Na2SO4, and K2SO4 aqueous solutions is compared. The electrochemical reaction of V2O5·0.6H2O in these neutral aqueous electrolyte solutions was elucidated by analyzing the different electrochemical behavior, structural and composition changes of V2O5·0.6H2O electrodes during charge/discharge. Results show, that V2O5·0.6H2O exhibits the largest specific capacity in K2SO4 electrolyte attributed to the most facile intercalation/deintercalation of K+-ions into/from the interlayer space of V2O5·0.6H2O.
