21. Advancements in Lithium-Based Batteries : Unraveling and Mitigating Performance-Limiting Phenomena in Negative Electrodes
Sammanfattning : The development of lithium-based batteries, especially lithium-ion batteries, has changed our daily lives significantly. The technologies first enabled by lithium-based batteries are now in turn creating a demand for better lithium-based batteries with higher energy densities and longer cycling lifetimes. LÄS MER
22. Strategies for finding new magnetic materials
Sammanfattning : Magnetic materials are indispensable in modern day society. The vast majority of energy generation and conversion involves some kind of magnetic material, and several other applications such as data storage also use them. LÄS MER
23. Synthesis and Characterization of Multifunctional Carbide- and Boride-based Thin Films
Sammanfattning : This thesis present research on synthesis, microstructure, and properties of carbide- and boride- based thin films. The films have been synthesized by dc magnetron sputtering, and their microstructures have been characterized mainly by X-ray photoelectron spectroscopy (XPS), X-ray diffraction, and transmission electron microscopy.

24. Investigation of compositionally complex refractory metal based thin films
Sammanfattning : The search for new and improved materials has led to the discovery and establishment of compositionally complex or high-entropy materials. The work in this thesis is focused on the investigation of new compositionally complex materials based on the refractory metals of groups 4-6. LÄS MER
25. Cladophora Cellulose-based Separators for Lithium Batteries
Sammanfattning : The development of lithium-ion batteries (LIBs) has been focused on exploring and improving the electrode materials and electrolytes in the past decades. An indispensable component, the separator, is however not studied as extensively. In general, a separator has two functions, i.e. LÄS MER
