How to Set Up a GITT Test Schedule in Arbin MITS Software

发布在

I. Introduction The Galvanostatic Intermittent Titration Technique (GITT) is an electrochemical method commonly used to study ion diffusion behavior and transport kinetics in battery electrode materials. A typical GITT test consists of a sequence of constant-current pulses followed by open-circuit relaxation periods. During each current pulse, the cell voltage changes as the state of charge […]

How Can Current Measurement Offset Make Coulombic Efficiency Appear to Exceed 100%?

发布在 , ,

One common reason that measured coulombic efficiency (CE) can appear to exceed 100% is a current measurement offset. In this example, assume the cycler has a constant negative current offset e. This means the measured current is lower than the true current by e throughout the test. To simplify the analysis, assume an ideal battery […]

Run the cycling test until the capacity decreases to 80% of original capacity

发布在 , ,

A common end-of-life criterion for lithium-ion cells is when the measured discharge capacity falls to 80% of its initial value. This document demonstrates how to configure an Arbin test schedule to automatically cycle a cell until this threshold is reached. Overall test procedure: Initial capacity measurement → Cycling loop → Compare capacity to 80% → […]
