1. Advancements in Lithium-Based Batteries : Unraveling and Mitigating Performance-Limiting Phenomena in Negative Electrodes
Abstract : 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. READ MORE

2. DIFFUSION OF IONS IN WOOD
Abstract : Wood sourced from well managed plantations or forests, is a renewable material with many advantages over non-renewable (fossil) material, and also wood lignocelluloses are the only type of biomass that is a seasonal-independent product. In addition to direct utilization as a building material, major uses of wood are currently for making pulp and paper products, and fuel. READ MORE

3. Electrical Properties of Gold-related Defect Complexes in Silicon
Abstract : This thesis describes three extensive experiments concerning the properties of gold as an impurity atom in crystalline silicon. The first study is an investigation of the effect of phosphorus diffusion on the distribution of gold atoms within a silicon crystal. READ MORE

4. An Experimental and Theoretical Study of the Mass Transport in Lithium-Ion Battery Electrolytes
Abstract : Lithium‐ion batteries are particularly suitable as energy storage solutions in high power applications, such as hybrid electric vehicles. It is generally considered that one of the processes that limit the power density for lithium‐ion batteries is the mass transport in the electrolyte. READ MORE

5. Electrochemical characterisations of TiO2 nanotube and lithium-metal electrodes for lithium-based batteries
Abstract : Lithium-ion batteries have since their introduction on the commercial market in the early 1990s played an important role within the field of energy storage. In this thesis both titanium dioxide, TiO2, and lithium metal are investigated based on their properties as anodes for lithium-based battery technologies. TiO2 nanotubes with lengths between 4.
