  1. 1. Investigating Brønsted Acidic Deep Eutectic Solvents for Recycling of Lithium Cobalt Oxide

    University essay from Uppsala universitet/Strukturkemi

    Author : Mattias Lindgren; [2022]
    Keywords : Deep eutectic solvents; Recycling; Lithium-Ion Batteries; Cathode Materials; LCO;

    Abstract : Recently, the production of lithium-ion batteries (LIB) has grown rapidly, highlighting the need for efficient and environmentally friendly recycling of LIB waste. In this work, the usage of so-called deep eutectic solvents (DESs) for the leaching of the LIB cathode material lithium cobaltoxide is investigated. READ MORE

  3. 2. Recycling of Textile and Plastic from an Interior Vehicle Component

    University essay from KTH/Fiber- och polymerteknologi

    Author : Esther Wennerstrand; [2021]
    Keywords : Polycarbonate; ABS; poly ethylene terephthalate ; mechanical recycling; chemical recycling; Polykarbonat; ABS; polyetylentereftalat; mekanisk återvinning; kemisk återvinning;

    Abstract : På grund av den rådande klimatförändringen och de globala problem som plast orsakar i miljön blir det allt viktigare att dagens linjära materialanvändning ändras till en cirkulär användning. Inom fordonsindustrin har kravet på ökad tillgänglighet och kvalitet på återvunna material identifierats. READ MORE

    Author : Sandra Mattsson; [2019]
    Keywords : CLEM; correlative light and electron microscopy; correlative microscopy; fluorescence microscopy; scanning electron microscopy; phase contrast microscopy; polymer blend; morphology; super yellow; PEO; poly ethylene oxide ; CLEM; korrelativ ljus- och elektronmikroskopi; korrelativ mikroskopi; fluorescensmikroskopi; svepelektronmikroskopi; faskontrastsmikroskopi; polymerblandning; morfologi; super yellow; PEO; poly etylenoxid ;

    Abstract : Semiconductors are used in many electronic applications, for example diodes, solar cells and transistors. Typically, semiconductors are inorganic materials, such as silicon and gallium arsenide, but lately more research and development has been devoted to organic semiconductors, for example semiconducting polymers.

  5. 4. Creating nanopatterned polymer films for use in light-emitting electrochemical cells

    University essay from Umeå universitet/Institutionen för fysik

    Author : Thomas Moberg; [2018]
    Keywords : Thermal nanoimprint lithography; soft stamp; intermediate polymer stamp; Light-emitting electrochemical cell; LEC; Super Yellow; polystyrene; poly ethylene oxide ; nanopattern;

    Abstract : Thermal nanoimprint lithography (T-NIL) is a cheap and fast technique to produce nanopatterns in polymeric materials. It creates these patterns by pressing a stamp down into a polymer film that has been heated above its glass transition temperature. READ MORE

  6. 5. Polymeric single Li+-ion conductors: preparation and characterisation

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Hannes Nederstedt; [2016]
    Keywords : single ion conductors; electrolytes; polymers; lithium ion batteries; polymer technology; polymerteknologi; Chemistry; Technology and Engineering;

    Abstract : Lithium-ion batteries are a common type of light-weight, rechargeable batteries. There are safety concerns because these batteries typically use an organic solvent electrolyte which presents fire hazards. By using dry polymer electrolytes, the fire hazards can be eliminated. READ MORE
