at the Technology Center Energy in Ruhstorf/Rott

The Technology Center Energy (TZE) of the University of Applied Sciences Landshut offers a thesis for a  

Master or bachelor student

in the field of lithium-ion battery development/production at the earliest possible date. The topic is

Preparation and optimization of lithium-iron-manganese-phosphate cathodes

Lithium-ion batteries (LIB) have been established over many years as an efficient storage medium with high energy and power densities. Several promising active material are being used or are under development. One of these active materials is lithium-iron-manganese-phosphate (LFMP), which shows a higher energy density compared to lithium-iron phosphate (LFP) as well as good properties concerning safety and performance. In standard use, LFMP is processed with a PVDF-binder by using NMP as a solvent. This solvent should be replaced by more compatible and ecologic substances. One approach is the use of acetone or/and the combination with another binder. The prepared electrodes will be later electrochemically tested in pouch cell format. This assignment provides an interesting introduction to the ever-growing field of energy storage research with a focus on LIB  and materials research. The activities in a pilot line as well as various characterization instruments offer the opportunity to gain a broad insight into the battery production and quality assurance possibilities.

The thesis will include:

·        Literature research on possible combinations of active material and binder or electrolyte

·        Production and characterization of electrodes in pouch cell format

·        Mechanical, morphological and electrochemical analysis of the prepared electrodes

Requirements:

·        Bachelor or master study (chemistry, material sciences, energy management, or equivalent)

·        Motivated, proactive personality, ability to work in a team

Set-up of an electrospinning-unit to optimize battery electrodes

Lithium-ion batteries have been established over many years as an efficient storage medium with high energy and power densities. Several promising active materials are being used or are under development. Due to progressive cost pressure, all other components of the cells (separator, binder, electrolytes) are also subjected to a permanent optimization process. One possible optimization step is the spinning of separators by fine polymer fibers, which is to be achieved by electrospinning. In this technique, the strong electric fields in a range of 100 – 500 kV/m are used to synthesis the fibers in the micro- to nanometer range between a metallic needle and a counter electrode. As a part of the thesis, experimental techniques for the spinning of polyolefin-materials shall be developed. Influence factors as polymer concentration (viscosity), applied voltage and ambient conditions are to be investigated. Subsequently, the materials are characterized both optically (light microscope, SEM) and mechanically. The main focus of the optical characterization is on the degree of wetting and its influencing factors.

The topic will include:

·        Literature research on useable and spinnable polymers

·        Spinning of membranes via electrospinning

·        Analysis of main influencing factors by optical and mechanical characterisation

Requirements:

·        Bachelor or master study (chemistry, physics, mechanical engineering or equivalent)

Use of electrospinning technique to optimize the battery electrodes

Lithium-ion batteries (LIB) have been established over many years as an efficient storage medium with high energy and power densities. Several promising active materials such as lithium titanate (LTO, Li₄Ti₅O₁₂), lithium iron phosphate (LFP) or lithium iron manganese phosphate (LFMP) are being used or are under development. Due to the high cost of active materials, all other components of the cells (separator, binder, electrolytes) are also subjected to a permanent optimization process. One possible optimization step is the spinning of separators by fine polymer fibers, which is to be achieved by electrospinning. In this process, strong electric fields in a range of 100 – 500 kV/m are used to synthesis the fibers in the micro- to nanometer range between a metallic needle and a counter electrode. As a result, a very precise application of fibers with variable degrees of wetting can be achieved. As a part of Master's thesis, separators are spun with different polymers and different factors such as polymer concentration, applied voltage and ambient conditions are investigated. Subsequently, the separators spun with the polymer fibers are characterized both optically (light microscope, SEM) and with regard to their electrochemical performance in the complete cell. The main focus of the optical characterization is on the degree of wetting and its influencing factors.

Am Technologiezentrum Energie der Hochschule Landshut wird eine Abschlussarbeit im Forschungsgebiet der Energiesystemanalyse ausgeschrieben. 

Aufgabenstellung:

Für den Wohnkomfort rückt die Gebäudekühlung immer mehr in den Fokus.  Um Kühlstrategien umzusetzen befinden sich verschieden Lösungen für große Wohn- und Geschäftshäuser auf den Markt.

In dieser Arbeit stehen jedoch moderne Einfamilienhäuser im Fokus, die kostengünstig und C0₂-arm gekühlt werden sollen. Es ist zu untersuchen welche Kühlleistung für diesen Gebäudetyp notwendig ist und welche Kühllösungen prinzipiell zum Einsatz kommen können (z.B. Luftwärmepumpe, zentrale/dezentrale Klimaanlage, Grundwassernutzung, …). Die Techniken sollen technisch, ökologisch und wirtschaftlich bewertet werden.  Die Techniken sollen per Parametervariation (Betrachtung von: 10 Jahre, Investitionskosten, laufende Kosten, Strompreisentwicklung, Primärenergieverbrauch etc.) verglichen werden.

Es stehen Daten für verschiedene moderne Einfamilienhäuser zur Verfügung, die als Referenz für die Auslegung genutzt werden können.

„CFD-Simulation der Umströmung eines Batteriewickels während eines Trock-nungsprozesses“ im Rahmen des Forschungsprojekts „InTenZ“

Projektpartner:
• Institut für Thermische Verfahrenstechnik, Karlsruher Institut für Technologie (KIT)
• Technologiezentrum Energie, Hochschule Landshut
• Institut für Partikeltechnik, Technische Universität Braunschweig

Das Projekt „InTenZ - Intensive Nachtrocknung von Komponenten für Lithium-Ionen-Zellen in diskon-tinuierlichen Trockenöfen“ adressiert diese Thematik und entwickelt ein Trocknungsmodell zur Be-schreibung der Wärme- und Stoffübertragung für Anoden-, Kathoden- und Separatorwickel während der Nachtrocknung. Über dieses Modell findet eine Prozessoptimierung zur Verkürzung der Prozess-zeiten bei gleichzeitiger materialschonender Wärmebehandlung statt. Die betrachteten Ebenen um-fassen dabei das Material, die Elektroden- und Separatorstruktur und komplette Wickel in verschie-denen Skalen.

Für das Wärmeübertragungsmodell wird konvektive und strahlungsbasierte Trocknung sowie die An-wendung von Inertgas und Unterdruck untersucht. Die Modelle und weitere Untersuchungen werden an industriell relevanten Stoffsystemen durchgeführt und auf weitere Materialien übertragen. Aus den Ergebnissen des Modells wird eine Prozessempfehlung für den diskontinuierlichen Trocknungs-schritt gegeben. Diese wird mit einem Demonstrator in Form eines Trockenschranks validiert. Durch Untersuchungen der Wiederaufnahme von Feuchte nach der Intensivtrocknung wird weiterhin eine Empfehlung zur Prozessumgebung gegeben.

Ihre Abschlussarbeit wird folgende Themenbereiche abdecken:

- Geometrieaufbereitung und Netzgenerierung
- Durchführung der CFD-Simulationen für konvektive Trocknung
- Durchführung des CFD-Simulationen für konvektive Trocknung mit Strahlungseintrag

Influence of different binder shares and electrolytes on the aging of electrodes

Lithium-ion batteries (LIB) have been established over many years as an efficient storage medium with high energy and power densities. A promising active material is lithium titanate (LTO, Li₄Ti₅O₁₂) with a working potential of 1.55 V against Li⁺/Li – the problem of electrolyte stability is thereby nearly excluded. High charging currents and very good chemical stability are further advantages of this material. To develop the existing technologies further, water based LTO electrodes will be prepared and electrochemically tested in LIB.  Different mixing formulations with various amounts of binders and electrolyte are to be compared and the influence of the individual materials examined. This assignment provides an interesting introduction to the ever-growing field of energy storage research with a focus on LIB and its materials research. The activities in a pilot line as well as various characterization instruments offer the opportunity to gain a broad insight into battery production and quality assurance possibilities.
