Module overview

Electrode reactions are inherently complex as they involve interfacial charge transfer, mass transport, many species, different timescales, thermodynamics and kinetics, as well as chemical, material and electrical properties. Furthermore the electron transfer may be complicated by adsorption and desorption of reactants or products, by solid state processes such as the insertion and extraction of ions and by the presence of two or three phases. To account for this complexity modern electrochemistry and electrochemical engineering research increasingly relies on simulations to predict the evolution of key electrochemical parameters, typically current, charge, electrode potential, cell voltage and impedance, during the course of an electrochemical process.

This module will introduce the key principles and techniques used to model electrochemical processes and produce qualitative and quantitative predictions of electrochemical parameters. Different computational and numerical methods will be considered through examples. Each case will start with the physical and chemical aspects of the model then move on to the computational or numerical approach appropriate for the problem. The module will consider dedicated electrochemistry modelling software such as DigiElch or DigiSim and general numerical modelling software such as Matlab and COMSOL Multiphyiscs.
