Abstract

We studied electrochemical alkaline systems whose Zn electrodes (anodes) contain active mass produced from composites of ZnO and B(Pb)SCCO 2212 conductive cuprate ceramics. The ceramics was added at concentrations of 5, 7 or 10 wt.%. The resulting material was structurally characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). Electrochemical cells assembled with anode prepared using active mass made by employing such composites, were examined by electrochemical impedance spectroscopy. The effect from the concentration of B(Pb)SCCO 2212 ceramics on the impedimetric response and tangent loss spectra of the electrochemical cells was studied. The results show that compared to 7 wt.% and 10 wt.% concentration of B(Pb)SCCO 2212 conductive ceramics added to the Zn material of the anode, the concentration of 5 wt.% leads to lower electric losses in the assembled electrochemical cells.
