How to fit transmission lines with ZFit (EIS transmission lines) – Battery – Application Note 43

Latest updated: August 31, 2021

Abstract

This application note describes how to fit transmission lines using one equivalent circuit elements contained in Z Fit. For example, the Warburg impedance is equivalent to that of a semi-infinite large network i.e. a transmission line.

 

Introduction

ZFit is the impedance fitting tool of EC-Lab®. This note will describe how to fit transmission lines using one equivalent circuit elements contained in ZFit. It has been well known for a long time that the Warburg impedance is equivalent to that of a semi-infinite large network i.e. a transmission line, as shown in Fig. 1 [1, 2].
