  1. 16. Wood-based Materials for Lithium-ion Batteries

    Författare :Lu Huiran; Göran Lindbergh; Ann Cornell; Claudio Gerbaldi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; binder; lignin; TEMPO-oxidized cellulose nanofibrils; flexible paper electrodes; lightweight; eco-friendly; Li-ion batteries; Chemical Engineering; Kemiteknik;

    Sammanfattning : Lithium-ion batteries (LIB) have become very important recently as power sources for portable electronics and electric vehicles. Today non-renewable petroleum-based polymers are used as binders in state-of-the-art LIB. Therefore, it is essential to investigate alternative binders, which are environmentally friendly and inexpensive. LÄS MER

  3. 17. Life cycle assessment of electric vehicle batteries and new technologies

    Författare :Mats Zackrisson; Magnus Wiktorsson; Martin Kurdve; Christina Jönsson; Anders Nordelöf; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life cycle assessment; LCA; electric vehicle; sustainability; eco-design; Production Engineering; Industriell produktion;

    Sammanfattning : Electrification of vehicles has for decades been explored as a possible solution to the problem of climate change. Today, in 2021, the issue is no longer whether the electrification of vehicle fleets ought to happen but rather how it can be achieved with as little environmental impact as possible. LÄS MER

  4. 18. Microbial Electrochemical System: extracellular electron transfer from photosynthesis and respiration to electrode

    Författare :Kamrul Hasan; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biological photovoltaics; electron transfer; electrode; Rhodobacter capslatus; thylakoid membranes; cyanobacteria; algae; photosynthesis; light; photocurrent; electrochemistry;

    Sammanfattning : The electrochemical communication between microorganisms and electrodes has substantial implications both for basic understanding of biological electron transfer as well as in diverse applications, such as, microbial electrochemical system (MES), microbial biosensors and in production of valuable chemicals. In these systems the extracellular electron transfer (EET) from microbial metabolism to electrodes is restricted due to the insulated cellular exterior made of lipid structures. LÄS MER

  5. 19. Experimental investigations of ageing of commercial BEV Li-ion batteries

    Författare :Kristian Bartholdsson Frenander; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon oxide; lithium plating; ageing; Physics-based modelling; Electric Vehicles; Lithium Ion Batteries; lifetime; NCA; State of Charge;

    Sammanfattning : The rapid development of lithium-ion batteries has enabled changes in widespread applications ranging from portable electronics to electric vehicles and large scale grid energy storage. However, battery ageing remain a challenge in all these applications, and this thesis seeks to contribute to the understanding of Li-ion battery degradation. LÄS MER
