| Summary: | 碩士 === 國立中興大學 === 化學系所 === 107 === This thesis discuss the MnO2 nanomaterials composited zinc ion on nickel foam as cathode electrode in Zinc Ion Battery. The materials fabricated by electrodechemical deposition from aqueouse 1 M Na2SO4 solution and 0.01 M MnSO4 solution as soure of MnO2 and ZnSO4 solution as source of zinc ion on nickel foam substrate. The electrodeposited MnO2 composite zinc (Zn-MnO2) result MnO2 gamma plane. The Zn-MnO2 electrochemical properties has been characterize by using cyclic votammetry and galvanostic charge/discharge analysis on coin cell 2032 type with potential range 1.0-1.8 V. The cyclic voltammograms shows of Zn-MnO2 is higher than pristine MnO2 as cathode on Zinc ion battery. Galvanostatic charge shows specific capacity of Zn-MnO2 ( 77.59 mAh/g) almost three times higher than pristine MnO2 (28.34 mAh/g) at current density 0.05 mA/cm2. The zinc composite improving the electrochemical activity of MnO2 conduce the specific capacity in Zinc Ion Battery. The Zn-MnO2 is a promissing cathode material for used in Zinc ion batteries.
