Battery cycling with reference electrodes using the PAT-cell test cell – Battery – Application Note 58

Latest updated: August 25, 2021

Abstract

Investigation on battery with a reference electrode becomes more and more common.  To achieve this goal, researchers need advanced testing cells along with advanced potentiostats/galvanostats. In this note, to show the advantage of a test cell equipped with a reference electrode, we describe a typical cycling experiment of a lithium-ion battery.

 

Introduction

 

Until recently, to study both the positive and the negative electrode of the battery, researchers investigated half-cells. Now it is becoming more and more common to study a battery with a reference electrode. [1-2] With this configuration, researchers can get information simultaneously from both electrodes. To achieve this goal, researchers need advanced testing cells along with advanced potentiostats/galvanostats. Because of the outstanding reliability of the built-in lithium metal reference electrode, the PAT-Cell is the ideal test cell for long-term 3-electrode experiments on Li-ion battery systems. In this device, the user can build an experiment cell and test the materials of the cathode and anode electrode. The Bio-Logic potentiostat/galvanostat is a perfect match for controlling this type of experiment, as it is capable of monitoring the half-cell voltages while controlling the full cell voltage. In this note, to show the advantage of the PAT-Cell equipped with reference electrode, we describe a typical cycling experiment of a lithium-ion battery comprised of an NMC…
