Cyclic Voltammetry is an analysis technique for characterizing the behaviours of electrochemically active materials by measuring current via defined potential sweeps. The current& amp; ndash; potential relationship depends on crucial variables such concentration associated with electrolyte, electron-transfer rate, as well as the distance and time of species in relation in order to the electroactive surface associated with the material. A MATLAB& amp; reg; simulation was developed on a diffusion plus kinetics basis, simulating the particular equations of Fick& amp; rsquo; s second law and Butler& amp; ndash; Volmer, respectively, towards understanding the energy-storage mechanisms associated with cobalt hydroxide electrodes. The particular simulation was compared to a real cobalt hydroxide system, showing an precise approximation to the experimentally obtained response and deviations possibly associated with other physical/chemical processes influencing the included species.
