1. 1. Adding utility to carbon materials: introducing dopants using highly soluble metal salts and functionalizing surfaces via bromomethylation

   Författare :Samuel Joseph Fretz; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbon; Doping; Surface functionalization; Li-S batteries; Fuel cell;

   Sammanfattning : Carbon-based materials have received intense research interest over the past few decades due to their outstanding combination of properties including porosity, non-toxicity, chemical inertness, low density, and electrical conductivity, which has allowed them to find a wide array of applications including supercapacitors, batteries, CO2 capture, fuel cells and catalysis. To expand their utility, a variety of techniques have been developed to enhance their reactivity and functionality. LÄS MER

4. 3. Modelling of Battery Electrolyte Interactions

   Författare :Gustav Åvall; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion batteries; semi-empirical Methods.; sodium-ion batteries; ab initio molecular dynamics; electrolytes; density functional theory;

   Sammanfattning : The rechargeable lithium-ion battery (LIB), powering our portable electronics, has transformed our everyday lives. Even though the success of the LIB there is a need for next generation batteries, due to a lack of abundant lithium and a need for greater performance and sustainable chemistries, in order to move towards a sustainable society with applications such as hybrid and electrical vehicles (EVs) and large scale energy storage for solar and wind power.
