A Pulse Voltammetry Analysis Toolkit for Battery and Fuel Cell Materials
Abstract
Pulse voltammetry (PV) encompasses a range of electroanalytical techniques utilizing a series of voltage pulses to study electrochemical reactions. These techniques provide numerous advantages over other electroanalytical techniques such as cyclic voltammetry (CV) and impedance spectroscopy by providing high sensitivity and discrimination against charging currents. Critically, this enables a more quantitative analysis of the voltammogram than is typical. In conjunction with mathematical models, PV can provide valuable quantitative information on the reaction kinetics, thermodynamics, and consistency with a hypothetical mechanism. Regression of experimental PV data against simulations, as opposed to comparing a limited set of features such as peak heights or full width at half-height, also enables the researcher to evaluate statistical confidence in the model and estimated parameters.
