Investigation of Dynamic Colloidal Thin Film Microstructure Using Electrochemical Impedance Spectroscopy (EIS)

Understanding the microstructural formation of colloidal films under varying processing conditions is relevant in applications like paints, food stuffs, and energy storage. The most common type of carbon-black thin film is a battery electrode, and recent studies have shown that the carbon distribution is largely responsible for electrode performance. This project aims to use electrochemical impedance spectroscopy (EIS), specifically dielectric spectroscopy, to discover facts about the behavior of a carbon black slurry under different processing conditions. This, in theory, will be an in-situ and non-invasive method of characterizing the carbon microstructure of a battery electrode in real time.
