CHM3005 – Batteries, Fuel Cells and Supercapacitors
Interactive tools to support your learning in electrochemistry
These interactive models help visualise key electrochemistry concepts covered in CHM3005. Use the sliders and controls to explore how changing parameters affects electrochemical systems.
Voltage & Current Explorer
Understand the relationship between voltage (thermodynamic driving force), current (kinetic flow rate), and resistance in electrochemical systems. Watch ions migrate and accumulate at electrodes as you apply voltage.
Launch Tool →
Electrochemical Series & Nernst Equation Explorer
Build custom electrochemical cells by selecting half-reactions from the electrochemical series. Calculate cell potentials and see how concentration affects voltage through the Nernst equation.
Launch Tool →
Butler-Volmer: Single Electrode Kinetics
Explore the Butler-Volmer equation for hydrogen reactions on platinum catalysts. Adjust overpotential and exchange current density to see how electrode kinetics determine current flow in fuel cells and electrolysers.
Launch Tool →
Butler-Volmer: Dual Electrode Kinetics
See how Butler-Volmer kinetics at two electrodes combine to determine battery performance. Explore charge and discharge modes, and understand how exchange current density at each electrode affects voltage losses in NiMH batteries.
