1. Characterisation of a structural battery composite and its constituents
Sammanfattning : The structural battery composite is a recently successfully developed multifunctional lithium-ion battery. It is safer and capable to carry mechanical load compared to commercially available liquid electrolyte batteries. LÄS MER
2. Proton-Conducting Sulfonated and Phosphonated Polymers and Fuel Cell Membranes by Chemical Modification of Polysulfones
Sammanfattning : The proton exchange membrane fuel cell (PEMFC) is currently emerging as an efficient and environmentally friendly power source. The technology is very complex and relies ultimately on materials and components which need further development. LÄS MER
3. Poly(phenylene oxide)s functionalized with cationic side chains: design, synthesis and properties as anion exchange membranes
Sammanfattning : Anion exchange membrane fuel cells (AEMFCs) are considered as one of the most important next-generation energy conversion technologies. AEMFCs convert chemical energy into useful electrical energy and have great potential forachieving high conversion efficiencies. LÄS MER
4. Structural Changes in Lithium Battery Materials Induced by Aging or Usage
Sammanfattning : Li-ion batteries have a huge potential for use in electrification of the transportation sector. The major challenge to be met is the limited energy storage capacity of the battery pack: both the amount of energy which can be stored within the space available in the vehicle (defining its range), and the aging of the individual battery cells (determining how long a whole pack can deliver sufficient energy and power to drive the vehicle).

5. Design and Characterisation of new Anode Materials for Lithium-Ion Batteries
Sammanfattning : Reliable ways of storing energy are crucial to support our modern way of life; lithium-ion batteries provide an attractive solution. The constant demand for higher energy density, thinner, lighter and even more mechanically flexible batteries has motivated research into new battery materials. Some of these will be explored in this thesis. LÄS MER
