What is Cyclic Voltammetry and how to use it in Arbin software

Cyclic Voltammetry sweeps a potential (or current) linearly between set limits at a fixed scan rate, then reverses it to form a complete cycle. It’s used to study redox reactions, kinetics, and the electrochemical behavior of materials.

In Arbin, a CV routine is defined at two levels:

• CV level: identifier (CV Label), number of sweep segments (Number of Stages), how many times it repeats (Repeat Number), the swept variable (CV 类型, e.g. Voltage), and the Base starting value.

• Stage level: each stage sets a Start, End，以及 Scan Rate for one linear ramp.

In the example above (CV_A), the Base stage sweeps 0 → 3 mV at 1 mV/s and Stage 2 sweeps 3 → 0 mV, producing the triangular potential-vs-time waveform shown.
