Электрохимический импеданс щелочного Mn-Zn элемента при различных температурах

Abstract

Electrochemical behavior of a Mn – Zn battery upon varying temperature was studied by electrochemical impedance spectroscopy. An equivalent circuit was proposed enabling one to numerically estimate the irreversible degradation of the battery. Analysis shows that on rising the temperature above 50 °C the corrosion rate of the anode material increases resulting in an increase in the inner resistance and decrease in the capacity of the battery.
