    Sammanfattning : Introduction: Research shows that the lifespan of large companies gets shorter and shorter, the average age of companies on the list of fortune 500 is 33 years, the average age is expected to decline to 12 years by 2027 (Anthony et al., 2018). LÄS MER

  2. 2. Safe, Sustainable Discharge of Electric Vehicle Batteries as a Pre-treatment Step to Crushing in the Recycling Process

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Nicole Nembhard; [2019]
    Nyckelord :;

    Sammanfattning : According to the Intergovernmental Panel on Climate Change, an increase in global temperature to above 1.5°C can be halted but would require immediate intervention to reach net zero emissions in the next 15 years. This intervention would have to make use of sustainable energy technologies such as net-zero carbon systems for automobiles. LÄS MER

  3. 3. Detection of lithium plating in lithium-ion batteries

    Master-uppsats, KTH/Kemiteknik

    Författare :Carl Johan Björkman; [2019]
    Nyckelord :Lithium plating; Batteries; Battery monitoring; Battery charging; Battery ageing; Litiumplätering; Batterier; Batteriövervakning; Batteriladdning; Batteriåldring;

    Sammanfattning : With an increasing demand for sustainable transport solutions, there is a demand for electrified vehicles. One way to store energy on board an electrified vehicle is to use a lithium-ion battery (LIB). This battery technology has many advantages, such as being rechargeable and enabling reasonably high power output and capacity. LÄS MER

  4. 4. Asymptotic Symmetries and Faddeev-Kulish states in QED and Gravity

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :David Gaharia; [2019]
    Nyckelord :Faddeev-Kulish; BMS; Bondi-Metzner-Sachs; Asymptotic Symmetries; Asymptotic States; Wilson Lines; Infrared Divergence; Bloch-Nordsieck; Large Gauge Transformations; Fock; QED; Quantum Electrodynamics; Perturbative Quantum Gravity; PQG; U 1 ; Transformations; Mandelstam Quantization;

    Sammanfattning : When calculating scattering amplitudes in gauge and gravitational theories one encounters infrared (IR) divergences associated with massless fields. These are known to be artifacts of constructing a quantum field theory starting with free fields, and the assumption that in the asymptotic limit (i.e. LÄS MER

  5. 5. Utformning av en standardiserad och utbytbar batterimodul till arbetsmaskiner

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Energy and Technology

    Författare :Martin Ericson; [2019]
    Nyckelord :elektrifiering av arbetsmaskiner; litiumbatteriets komponenter och system; modulsystem; framtidens lantbruk; skogsbruk och entreprenad;

    Sammanfattning : The purpose of this master thesis was to clarify how a standardized and replaceable battery module for working machines can be constructed together with the necessary components and systems. For example were battery technology, cell format, charge and discharge intervals, working temperature, the need of cooling etc. investigated. LÄS MER
