16. Highly Concentrated Electrolytes for Lithium Batteries : From fundamentals to cell tests
Sammanfattning : The electrolyte is a crucial part of any lithium battery, strongly affecting longevity and safety. It has to survive rather severe conditions, not the least at the electrode/electrolyte interfaces. LÄS MER
17. The role of interfaces in oxide thin films
Sammanfattning : The role of interfaces in oxide thin films has been investigated from a microstructural point of view. Thin films of manganites and titanates have been investigated by transmission electron microscopy (TEM). LÄS MER
18. LiFeSO4F as a Cathode Material for Lithium-Ion Batteries : Synthesis, Structure, and Function
Sammanfattning : In this thesis, two recently discovered polymorphs of LiFeSO4F, adopting a tavorite- and triplite-type structure, were investigated as potential candidates for use as cathode materials in Li-ion batteries. The studies aimed at enriching the fundamental understanding of the synthetic preparations, structural properties, and electrochemical functionality of these materials. LÄS MER
19. Nanoconfined imidazolium ionic liquids
Sammanfattning : Long-chain ionic liquids are attracting interest as alternatives to their short-chain analogues as electrolytes. At the same time, they are also considered as alternatives to mesogens and conventional surfactants as templates. LÄS MER
20. Semiconductor-ionic Materials for Low Temperature Solid Oxide Fuel Cells
Sammanfattning : Solid oxide fuel cell (SOFC) is considered as an attractive candidate for energy conversion within the fuel cell (FC) family due to several advantages including environment friendly, use of non-noble materials and fuel flexibility. However, due to high working temperatures, conventional SOFC faces many challenges relating to high operational and capital costs besides the limited selection of the FC materials and their compatibility issues.
