Cyclic voltammetry performance of negative electrode in Zn/Ni battery

TANG You-gen, TANG Zan-qian, SANG Shang-bin(Chemical Power Source and Material Institute, College of Chemistry & Chemical Engineering, Central South University, Changsha, Hunan 410083,China)  
The cyclic voltammetry performance of active material which was respectively made of ZnO,CaZnO_2 and Zn_4SO_4(OH)_6 in negative electrode of Zn/Ni battery was tested by powder microelectrode in 1.8?mol/L K_2CO_3,1.8?mol/L KF and 3?mol/L KOH alkaline electrolyte. The relationship between current,potential in peak value and scan rate was studied as well as the reversible interval of cyclic voltammetry of active materials in negative electrode of Zn/Ni battery was derived. The reversibility among active materials was compared and the result showedthe reversibility of zinc oxide was the best. The equal electrode potentials of negative electrodes were calculated in the reversible interval.
