摘要
Silver vanadate(Ag_(0.33)V_(2)O_(5))nanorods were successfully synthesized by the pre-intercalation of Ag+into the interlayer of V_(2)O_(5)through a sol-gel method,which presented a favorable electrochemical performance of high capacity,rate capacity,and cycle stability.Specific ally,Ag_(0.33)V_(2)O_(5)electrode presented a high capacity of about 311 mAh·g^(-1)at the current density of0.1 A·g^(-1).It also delivered long-term cycling stability(144 mAh·g^(-1)after 500 cycles at 2 A·g^(-1)).The reasons for the superior electrochemical performance were the preintercalation Ag^+extended interlayer distance,and the introduction of elemental silver improved conductivity during charge/discharge.Additionally,the Zn^(2+)storage mechanism was revealed by various characteristic measurements.The prepared Ag_(0.33)V_(2)O_(5)nanorods from the sol-gel method were demonstrated as a promising cathode material for aqueous Zn^(2+)batteries.
