Cyclic (or linear sweep) Voltammetry Models

Soluble-Insoluble Reactions

Electrodeposition is a common soluble-insoluble reaction. A few models for calculating a couple properties are available at the github links below.

Advanced Simulator

This model simulates the cyclic voltammetry response of an electrodeposition reaction in molten salts. It accounts for uncompensated resistance, semi-infinite linear diffusion, migration, adsorption (deposition onto a foreign substrate), and activity effects of dissolved analytes. It is currently under development to account for radial diffusion and natural convection. Additional effects, such as kinetics and surface area growth, will also be implemented, but will require longer developmental times.

Diffusion Coefficient

Two files are provided in the repository linked above. One uses the solver, and the other uses a macro. Descriptions of each file are provided in the linked repository. These files account for the activity effects encountered when depositing onto a foreign substrate and/or using a digital staircase instead of a true linear (analog) scan for reversible reactions. However, it does not account for uncompensated resistance.

Standard Apparent (or Formal) Potential

The linked file can be used to calculate the standard apparent potential from the peak potential of cyclic voltammetry reduction peaks correlated to the deposition of metal onto a foreign substrate. The model assumes semi-infinite linear diffusion and reversible soluble-insoluble reactions. The model accounts for: (1) reversible reactions, (2) deposition onto a foreign substrate, (3) digital staircase instead of a true linear scan, and (4) uncompensated resistance.
