  1. 11. High entropy oxide electrodes with ionic liquid electrolyte

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Saron Abraham; [2022]
    Keywords : High entropy oxides; electrodes; Lithium batteries; ionic liquids; electrochemistry;

    Abstract : Metal-based high entropy oxides are considered promising electrode materials for use in Li- ion batteries. In this work, the most widely studied high entropy oxide Mg0.2Ni0.2Cu0. READ MORE

  3. 12. 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.

  4. 13. An Initial Exploration of Transition Metal Nitroprussides as Electrode Materials for Sodium-ion Batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Veronica Enblom; [2022]
    Keywords : Sodium-ion batteries; Transition metal nitroprussides; Electrode materials; Prussian blue analogues; Cathode materials; Nitrosyl redox; Anisotropic charge transfer; Hysteresis; Sustainable batteries;

    Abstract : Na-ion batteries (NIBs) are expected to revolutionise the battery sector by promising an affordable technology while capitalising on sustainable development. To compete with Li-ion batteries, however, electrode materials with higher capacities need to be developed. READ MORE

  5. 14. Investigating Particle Cracking in Single- and Polycrystalline Nickel-Rich Cathodes using In Situ Impedance Spectroscopy

    University essay from Uppsala universitet/Strukturkemi

    Author : Mattias Sjödin; [2021]
    Keywords : Electrochemical surface area; particle cracking; NMC811; transmission-line model; equivalent-circuit fitting; commercial Li-ion batteries;

    Abstract : State-of-the-art Li-ion cathode materials are based on LiMO2 (M=Ni, Mn, Co) layered transition metal oxides (denoted NMC) with Ni-rich composition because of their high specific capacity. Yet, these materials suffer from poor capacity retention due to crack formation during de-/lithiation cycling. READ MORE

  6. 15. REMOTE PULSE MONITORING USING MILLIMETER WAVES

    University essay from Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

    Author : PRAFULL GARG; [2021]
    Keywords : Frequency-Modulated Continuous Waveform; Pulse Monitoring; E-Health; Ultra-Wide Band; Millimeter Waves;

    Abstract : With the population aging worldwide, new solutions for non-invasive health monitoring are required. Radar systems have been proposed as a promising technology for monitoring vital signs in ambient assisted living (AAL) applications. READ MORE
