1. Diffraction as a tool in the study of mechanisms for ionic conductivity in solids
Sammanfattning : .... LÄS MER
2. Exploring the dual nature of engineering education : Opportunities and challenges in integrating the academic and professional aspects in the curriculum
Sammanfattning : Engineering education is both academic, emphasising theory in a range of subjects, and professional, preparing students for engineering practice. Ideally, these aspects are also in a meaningful relationship in the curriculum, but the dual nature ideal is simultaneously a source of tensions. LÄS MER
3. The Electrochemistry of LiNi0.5-xMn1.5+xO4-δ in Li-ion Batteries : Structure, Side-reactions and Cross-talk
Sammanfattning : The use of Li-ion batteries in portable electronic products is today widespread and on-going research is extensively dedicated to improve their performance and energy density for use in electric vehicles. The largest contribution to the overall cell weight comes from the positive electrode material, and improvements regarding this component thereby render a high potential for the development of these types of batteries.

4. Multifunctional Carbon Foams by Emulsion Templating : Synthesis, Microstructure, and 3D Li-ion Microbatteries
Sammanfattning : Carbon foams are among the existing electrode designs proposed for use in 3D Li-ion microbatteries. For such electrodes to find applications in practical microbatteries, however, their void sizes, specific surface areas and pore volumes need be optimized. LÄS MER
5. Avoiding ageing : Surface degradation of commercial electrode materials in lithium-ion batteries
Sammanfattning : The battery market today expands rapidly, not least for electric vehicles. But to compete against the combustion engine, the cost of batteries must be reduced. After years of usage, the batteries degrade and need to be exchanged, increasing the cost over the vehicle lifecycle. LÄS MER
