2. 1. Avoiding ageing : Surface degradation of commercial electrode materials in lithium-ion batteries

   Author : Erik Björklund; Kristina Edström; Daniel Brandell; Reza Younesi; Frank Renner; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Li-ion battery; Ageing; Photoelectron spectroscopy; Nickel Manganese Cobalt Oxide;

   Abstract : 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. READ MORE

4. 2. Studies on the Recovery of Secondary Antimony Compounds from Waste

   Author : Toni Karlsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Morphology; Thermolysis; Leaching; Municipal Solid Waste; Zinc; Metal Oxide Varistor; Cementation; Fly Ash; Recycling; Antimony;

   Abstract : The global supply of antimony is dominated by one country which has led the European Union to classify antimony as a critical raw material. Other than the rare-earth elements antimony has the highest supply risk. Therefore, a feasibility study on the recycling of antimony and antimony compounds is of great importance. READ MORE

5. 3. Preparation of New Catalytic Materials by Small Particle Technology

   Author : Anders Törncrona; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : New techniques for preparation of catalytic materials with novel properties are presented in this thesis. Three new catalytic materials; washcoated fibres, highly dispersed metal oxides on titania coated silica particles and discrete colloidal ZSM-5 crystals with a low SiO2/Al2O3 ratio have been prepared and characterised.

   Abstract : This thesis explores how the systemic-level environmental footprint of light-duty vehicles could be reduced through integrative design using the Life Cycle Energy Optimisation (LCEO) methodology. This methodology aims at finding a design solution that uses a minimum amount of cumulative energy demand over the different phases of the vehicle's life cycle; while complying with a set of functional constraints, thereby avoiding any sub-optimal energy demand shifts between the vehicle's different life cycle phases.
