  2. 16. Characterization of Reaction Products in the Li-O2 Battery Using Photoelectron Spectroscopy

    Author : Reza Younesi; Kristina Edström; Patrik Johansson; Fredrik Björefors; Gabriel Veith; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Li-O2 Battery; Surface Characterization; Lithium-Air Battery; Photoelectron Spectroscopy; XPS; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Abstract : The rechargeable Li-O2 battery has attracted interest due to its high theoretical energy density (about 10 times better than today’s Li-ion batteries). In this PhD thesis the cycling instability of the Li-O2 battery has been studied. READ MORE

  4. 17. Cost and financing of the sustainability transition of the Swedish road freight transport sector

    Author : Elmira Parviziomran; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Godstransporter; Hållbar utveckling; Fossila bränslen; Fordon; Kostnader; Finansiering; Batterier; Sustainable development; Electric batteries; Vehicles; Freight and freightage; Fossil fuels; Sustainability transition; Decarbonization; Heavy-duty vehicles; Cost; Financing; Battery; Circular economy; Diesel fuels;

    Abstract : The cost and financing of the road freight sector’s sustainability transition, driven by significant greenhouse gas (GHG) emissions and cost considerations, represent an urgent yet underexplored research focus. This study investigates the costs of fleet replacement with zero-emission powertrains, battery electric vehicles (BEVs) and fuel cell vehicles (FCVs), emphasizing cost variables that have been overlooked in transition research.
