V2O5发泡材料的制备及电化学性能
Preparation and electrochemical performance of V2O5 foaming material
摘要
Abstract
Vanadium pentoxide(V2O5) xerogels were prepared by melt cooling method with V2O5 as raw material,V2O5 materials with layered structure were obtained using organic amine as intercalation compounds and structure directing agent.The SEM,XRD and BET were used to analyses V2 O5 raw material,xerogel and foaming material.The electrochemical performance was tested by cyclic voltammetry,galvanostatic charge-discharge and AC impedance methods.While m(V2 O5)∶ m(C16 H35 N)∶ m (H2 O2) =1∶ 2∶ 50,V2 O5 foaming material had better electrochemical performance.When charged-discharged with the current of 0.2 A/g in-0.2-0.8 V,the charge specific capacitance was 170.3 F/g in the solution of 1mol/L Na2SO4.关键词
