    Nyckelord :;

    Sammanfattning : As the energy transition progresses, the demand for green storage solutions is ever-increasing. Hydrogen storage is receiving increased interest and support due to its promising sustainability and flexibility. Proton-exchange, or polymer electrolyte, membrane (PEM) electrolyzers are a key technology supporting hydrogen storage systems. LÄS MER

  4. 3. Waste-derived hard carbon anode materials for sodium-ion batteries : The potential of using cardboard as precursor material in sodium-ion batteries for hard carbon production in Sweden

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Axel Björlin; Alexander Hansson; Yanxi Lucie Zhou; [2023]
    Nyckelord :;

    Sammanfattning : In recent years, sodium ion batteries (SIBs) have emerged as a strong contender to lithium-ion batteries (LIBs). The most promising anode for the SIBs is hard carbon (HC), which can be derived from a wide variety of raw materials and waste globally. LÄS MER

  5. 4. A method development and complete validation of coin half-cell test procedure

    Master-uppsats, KTH/Kemiteknik

    Författare :Prasad Korde; [2022]

    Sammanfattning : ”Coin cell”-tillverkningen täcker hela processen från NMC-pulver till faktisk cell- och prestandautvärdering genom att cykla celler. Nydanande utveckling av elektrodmaterialen är nyckeln till att öka energitätheten hos litium-jon/metall-batterier för elfordon och nätlagring. LÄS MER

  7. 5. Ageing of NCA/Graphite-Silicon Cells : Investigating the feasibility of accelerated ageing

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Gustav Giske; [2022]
    Nyckelord :;

    Sammanfattning : Reliable test data on cell ageing is important to have when deciding on which cell to use in a vehicle. Accelerated ageing could, if performed in a good way, increase the amount of information about the cell ageing in an early stage of a vehicle project, reducing the risk of costly battery replacements.
