Journal Title: Фізика і хімія твердого тіла - Year 2016, Vol 17, Issue 2
Abstract
The influence on specific discharge characteristics of redox - active iodide and bromide electrolytes of polyaniline as the cathode material in electrochemical energy sources with zinc anode was studied. Electrochemical and capacitive properties of PAN cathode was investigated using galvanostatic, potentiostatic, cyclic voltampermetric and impedance methods. It was established that PAN cathode inherent discharge specific capacity of Ср = 126 A × h × kg-1 with current load і = 103 A × kg-1 in zinc - sulfate electrolyte and Ср = 301 A × h × kg-1 in the same conditions in the presence of KI. Thus there is a reverse transition of various forms of PAN leucoemeraldine / emeraldine, that among the redox electrolyte causes increase in electrical capacitance and conductivity of PAN electrodes in the charged state.
