ELECTROCHEMISTRY / TOOL 02

Tafel analysis calculator.

Estimate electrode potential and activation overpotential from current density and fitted kinetic parameters.

INPUT PARAMETERS

Tafel parameters

Reference potential, E₀ (V)

Tafel slope, b (mV dec⁻¹)

Exchange current density, j₀ (mA cm⁻²)

Current density, j (mA cm⁻²)

Branch

Model: η = b log₁₀(|j|/j₀). E = E₀ ± η according to the selected branch. Use parameters fitted with consistent reference and unit conventions.
