Characterisation of nickel electrodes by electrochemical impedance spectroscopy
thesis
posted on 2013-04-29, 13:21 authored by Ray T. BartonThe thesis describes an electrochemical investigation of different types of nickel
electrode used in nickel-cadmium cells, which are available commercially or currently
under development. Impedance spectroscopy has been used to determine the
electrochemical characteristics of these electrodes. The electrochemistry of the nickel
electrodes was modelled by the electrical analogue method. Allowance was made within
the model for porosity and adsorption effects. Component values were initially estimated
by graphical techniques and the computer fitting procedure was then completed by an
iterative process to provide kinetic parameters which were used to compare and contrast
the characteristics of the nickel sintered, pocket and plastic bonded electrodes.
The technological target of this work was establish a possible method by which
the residual capacity remaining within nickel-cadmium cells could be determined. The
kinetic parameters generated by the electrical analogue technique have provided data on
which to base a measurement for the prediction of the state of charge in nickel-cadmium
cells.
