  1. 1. Lithium-ion Battery Modeling and Simulation for Aging Analysis using PyBaMM

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Amina Coric; [2022]
    Keywords : Battery charging; Lithium-ion; Doyle-Fuller Newman; P2D; Single Particle Model; Pulse Charging; Constant Current Constant Voltage; Solid Electrolyte Interphase; SEI; Lithium Plating; Cycle Life; Cyclic Aging; PyBaMM; Batteri laddning; Litiumjonbatteri; Doyle-Fuller Newman; P2D; Singelpartikelmodell; Pulsad Laddning; Konstant Ström Konstant Spänning; Fast Elektrolytinterfas; SEI; Litiumplätering; LP; Cykellivslängd; Cykliskt Åldrande; PyBaMM;

    Abstract : The rate of degradation of a lithium-ion battery depends on its use i.e. how it is charged and discharged. Physics-based models are used to represent the processes inside a cell as well as the degradation mechanisms. READ MORE

  3. 2. Modelling of Fluid Flow and Contaminant Transport in Fractured Rock : Case Study

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ebba Pegestam; [2022]
    Keywords : Contaminant transport; Discrete Fracture Network; Geology; Geohydrology; Groundwater transport; Fracture; Drinking water; Contamination; Föroreningar; flödestransport; spricknätverk; geologi; geohydrologi; grundvattentransport; sprickor; dricksvatten;

    Abstract : Drinking water contamination is a big concern in Sweden and is commonly traced back to being waste from former manufacturing industrial sites. Pollutants in the topsoil can be remediated by several techniques, such as decontamination or excavation but the toxins already enclosed in the bedrock cannot be treated the same and is harder to track possible contaminant pathways.

  4. 3. Physics-Based Modelling for SEI and Lithium Plating During Calendar and Cycling Ageing

    University essay from KTH/Kemiteknik

    Author : Oskar Nordlander; [2022]
    Keywords : Lithium-ion Battery; Calendar Ageing; Cycling Ageing; Battery Degradation; Physics-Based Modelling; SEI; Lithium Plating; Litium-jonbatterier; Kalenderåldring; Cykling åldrande; Batteriåldrande; Fysikbaserad Modellering; SEI; Litium Plätering;

    Abstract : Målet med projektet var att undersöka samt implementera en fysikbaserad DFN modell för att simulera kalender samt cyklingåldrande av litiumbatterier som används i elbilar. Den fysikbaserade modellen var konstruerad baserad på ett Python biblioteket vid namn PyBaMM, vilket till skillnad från datadrivna modeller ger essentiell information om de kemiska processerna inuti batteriet.

  6. 5. Elastic properties of the Singö zone from a discrete approach

    University essay from KTH/Skolan för arkitektur och samhällsbyggnad (ABE)

    Author : Amanda Åkerlind; [2019]
    Keywords : Elastic properties; deformation zones; Forsmark; Singö zone; DFN; Deformationsegenskaper; deformationszoner; Forsmark; Sinözonen; DFN;

    Abstract : A rock mass is characterised by the properties of the intact rock and the fractures. Considering the impact of both constituents is of vital importance for assessing the behaviour of the rock mass. In particular in the case of complex or heterogeneous rock mass compositions. READ MORE
