How to Set Up a GITT Test Schedule in Arbin MITS Software
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%?
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
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% → […]
Application Examples of User-Defined MetaVariables (MV_UD)
In Arbin software, MV_UD (short for User-Defined Meta Variables) is a powerful tool for controlling battery testers. This article explains how to use MV_UD in Arbin MITS software. Storing Values in MV_UD with SetValue(s) In the Control Type list, select SetValue(s). SetValue(s) assigns a fixed value of a physical quantity at a specific moment to […]

Accuracy and Precision: Impact of Precision
We previously examined the impact of measurement accuracy in an earlier article. In this article, we shift our focus to the influence of a battery tester’s precision on battery research. In many research applications, parameters such as dV/dt and dQ/dV are widely used. The reliability of these measurements depends heavily on the precision of the […]
