„Europa hat in der Batteriezellenproduktion Aufholbedarf!“ “Europe has some catching up to do in battery cell production!”

Bernd Eschelmüller wollte beruflich immer etwas mit Fahrzeugen machen. Dieses Ziel hat er in den vergangenen Jahren konsequent verfolgt: von der Maschinenbau-HTL mit Schwerpunkt Kraftfahrzeugtechnik bis zum Master­ abschluss in Green Mobility an der FH Campus Wien. Heute arbeitet er als Junior Research Engineer am AIT Austrian Institute of Technology GmbH und forscht dort im Bereich Battery Technologies an der industrienahen Optimierung von Batterieproduktionsprozessen für die Elektromobilität.

Bernd Eschelmüller always dreamed of working with cars. He has consistently pursued this goal in recent years: from the mechanical engineering college with a focus on automotive engineering to the master’s degree in Green Mobility at FH Campus Wien. Today, he works as a Junior Research Engineer at the AIT Austrian Institute of Technology GmbH, where he conducts research in the Battery Technologies division on the industry-oriented optimization of battery production processes for electromobility.

In Kontakt mit dem AIT Austrian Institute of Technology GmbH kam Bernd Eschelmüller im Zuge seiner Masterarbeit, die er im Rahmen einer befristeten Diplomandenstelle an Österreichs größter außeruniversitärer Forschungseinrichtung schrieb. „Bekanntlich tragen Elektrofahrzeuge besonders im Individualverkehr wesentlich dazu bei, den Treibhausgasausstoß zu reduzieren. Li-Ionen-Batterien spielen dabei eine zentrale Rolle. Sie speichern elektrische Energie, und wie gut sie das tun, wird maßgeblich vom Produktionsprozess beeinflusst“, erklärt Eschelmüller. In seiner Abschlussarbeit untersuchte der Green Mobility-Absolvent die kritischen Produktionsparameter in der Batteriezellenfertigung, um daraus Informationen abzuleiten, die die Leistungsfähigkeit zukünftiger Batterien verbessern. „Es gibt bei der Herstellung von Li-Ionen-Batterien einen definierten Prozess, der sich in mehrere kleinere Teilschritte gliedert. In meiner Masterarbeit habe ich mich auf den Bereich der Zell­ assemblierung, also den Zellzusammenbau, konzentriert.“

Bernd Eschelmüller came into contact with the AIT Austrian Institute of Technology GmbH in the course of his master’s thesis, which he wrote as part of a temporary diploma position at Austria’s largest non-university research institution. “It is well known that electric vehicles make a significant contribution to reducing greenhouse gas emissions, especially in private transport. Li-ion batteries play a central role in this. They store electrical energy, and how well they do so is largely influenced by the production process,” explains Eschelmüller. In his thesis, the Green Mobility graduate examined the critical production parameters in battery cell production in order to gain information that will improve the performance of future batteries. “There is a defined process in the production of Li-ion batteries that is divided into several smaller sub-steps. In my master’s thesis, I focused on the area of cell assembly.”

Know-how aufbauen Der Zellproduktionsprozess wird von verschiedenen Parametern beeinflusst. Bernd Eschelmüller untersuchte, welche davon wirklich kritisch sind und wieweit Fehler die Performance einer Zelle beeinträchtigen. In 16 Versuchsreihen, in die er verschiedene simulierte Fehler einbaute, identifizierte er, welche Fehler welchen Einfluss auf die Zellfunktion haben. Er quantifizierte die

Building know-how The cell production process is influenced by various parameters. Bernd Eschelmüller examined which of them are truly critical and to what extent errors affect the performance of a cell. In 16 test series, in which he incorporated various simulated errors, he identified which errors have which influence on the cell function. He quantified the influences of the examined process parameters and carried out a screening design in order to obtain a trend of the effects of the process errors on the performance character-
