Abstract

For the purpose of electrochemical applications (such as Ni-Zn batteries), we have experimentally studied the electrical impedimetric response of electrochemical systems (ECSs), in which the anodes were fabricated from nano-sized ZnO material doped with high-temperature superconducting ceramics Bi1.7Pb0.3Sr2CaCu2Oy (B(Pb)SCCO 2212) at concentration of either 5, 7, or 10 wt%. The electro-conducting properties of such ECSs with alkaline electrolyte were characterized at ambient temperature by measurements with electrochemical impedance spectroscopy in the frequency range 0.1 Hz –100 kHz. The effect from the ceramics additives on both complex electrical impedance and electrical conductivity of the examined ECSs was estimated.
