Effective Teaching Method on Impedance Spectrum of Electrochemical Cell using Microsoft Excel for Beginners in Electrochemistry

This study examined an impedance learning methodology applicable to electrochemical cells using Microsoft (MS) Excel Software. MS Excel, a tool commonly used by practitioners in chemical engineering, can provide an educational platform for analysing and understanding the complex impedance characteristics of electrochemical cells. The impedance learning method using MS Excel aims to increase the efficiency of impedance education by providing a user-friendly interface for beginners and experts in electrochemistry. This paper proposes using the MS Excel functions to simplify data input, processing, and interpretation for each component within the various impedance circuit patterns in electrochemical cells. This information caters to students aspiring to engage in the research and development of next-generation electrochemical cells, serving as an educational resource for grasping the concept of impedance with ease. This study will also be helpful to researchers in various application fields, including the development of electrochemical sensors and energy storage systems.
