  3. 2. Pulse Charging of Li-ion Batteries for Enhanced Life Performance

    Master-uppsats, KTH/Kemiteknik

    Författare :Josefin Strandberg; [2023]
    Nyckelord :Li-ion battery; Pulse charging; Cyclic aging; Capacity fade; Internal resistance; Battery impedance; Litiumjonbatteri; Pulsad laddning; Cyklisk åldring; Kapacitetsminskning; Inre resistans; Batteriimpedans;

    Sammanfattning : Det överhängande behovet av att minska utsläppen av växthusgaser för att uppfylla Parisavtalet har väckt ett ökat intresse för elektrifiering som en strategi för att mildra klimatförändringarna. Litiumjonbatterier spelar en central roll vid elektrifiering och har framträtt som det primära alternativet för batteridrivna elfordon. LÄS MER

  4. 3. On the stability of current collectors in high-voltage lithium-ion batteries containing LiFSI electrolytes

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Oorganisk kemi

    Författare :Kevin Carlö; [2023]
    Nyckelord :LiFSI; high-voltage; anodic dissolution; corrosion; aluminum; current collector; electrolyte; battery;

    Sammanfattning : The increasing energy demand requires a transition from fossil fuels to renewable resources. Lithium-ion batteries (LIBs) offer a promising solution as efficient energy storage devices. However, the aluminum current collector (CC) in LIBs is susceptible to anodic dissolution above 3 V vs. LÄS MER

  5. 4. Comparative Analysis of the Inverse Kinematics of a 6-DOF Manipulator : A Comparative Study of Inverse Kinematics for the 6-DOF Saab Seaeye eM1-7 Manipulator with Non-Conventional Wrist Configuration

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Anton Larsson; Oskar Grönlund; [2023]
    Nyckelord :;

    Sammanfattning : This report presents various methods for solving the inverse kinematic problem for a non-conventional robotic manipulator with 6 degrees of freedom and discusses their respective advantages and disadvantages. Numerical methods, such as gradient descent, Gauss-Newton and Levenberg-Marquardt as well as heuristic methods such as Cyclic Coordinate Descent and Forward and Backward Reaching Inverse Kinematics are discussed and presented, while the numerical methods are implemented and tested in simulation.

  7. 5. Central Banks' Effect on Bitcoin Returns: An Event Study

    Kandidat-uppsats, Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Författare :Filip Lundqvist; Christian Olivefors; [2022-07-08]
    Nyckelord :Event Study; Bitcoin; Efficient Market Hypothesis; Cryptocurrency; Monetary Policy Tool; Blockchain;

    Sammanfattning : Bitcoin has become established in the financial system and has a volatile price development. Lacking trust in the financial system and monetary policy has led to increased adoption of Bitcoin. The regulation of Bitcoin can be hard to succeed with. The thesis will study the impact of central bank statements from ECB and FED on Bitcoin’s returns. LÄS MER
