  3. 2. Ageing of NCA/Graphite-Silicon Cells : Investigating the feasibility of accelerated ageing

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Gustav Giske; [2022]
    Keywords : ;

    Abstract : 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.
