An interactive browser-based visualisation of Cyclic Voltammetry (CV), built with Chart.js and vanilla JavaScript. Designed as an educational tool and LinkedIn post companion for a series on electrochemical characterisation techniques in energy storage research.
Drag the sliders and watch a physically accurate voltammogram update in real time:
- Scan rate (ν) — peak current scales with √ν per the Randles-Ševčík equation
- Reversibility — peak separation ΔEp widens as the system moves from reversible → quasi-reversible → irreversible
- Number of electrons (n) — peaks sharpen and shift inward as n increases
Live metric cards update continuously:
| Parameter | Meaning |
|---|---|
| Epa | Anodic peak potential |
| Epc | Cathodic peak potential |
| ΔEp | Peak separation (59/n mV for ideal reversible) |
| |Ipa/Ipc| | Peak current ratio (≈ 1.00 for reversible) |
