  1. 6. Battery Storage as Grid Reinforcement for Peak Power Demands

    Master-uppsats, Linköpings universitet/Energisystem

    Författare :Jesper Hilleberg; [2023]
    Nyckelord :Battery Storage; Battery Energy Storage System; Grid Reinforcement; Flexibility; Lithium-ion battery; li-ion battery; Large Scale Grid Storage; BESS; Energy Storage; Peak Power Demand; Batterilagring; Batterilagringsystem; Nätförstärkning; Nätförstärkningsåtgärd; toppeffektlaster; Flexibilitet; Flexibilitetslösning; litiumjonbatteri; li-ion batteri; BESS; energilagring;

    Sammanfattning : An increased amount of intermittent electricity production, more electric vehicles (EV), and an overall electrification of society may all cause a higher variability between the balance of supply and demand on the electric grid. Battery storage has been identified as a solution to the emerging problem asit can be charged during hours of low power demand and then discharged to help meet the power demand during peak loads.

  3. 7. Life cycle assessment on sodium-ion cells for energy storage systems : A cradle-to-gate study including 16 environmental perspectives, focusing on climate change impact

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Rebecca Nibelius; [2023]
    Nyckelord :Sodium-ion batteries; Life cycle assessment; Cradle-to-gate; Natriumbatterier; Livscykelanalys; Vagga-till-port;

    Sammanfattning : Because of the changing energy supply landscape, with the transition towards renewable energy, an emerging demand for energy storage systems (ESS) is expected in the near future. Battery energy storage is promising to contribute to mitigate the greenhouse gas emissions, but face issues considering resource use (IEA, 2023; IRENA, 2022). LÄS MER

  4. 8. Sublimation temperature prediction of OLED materials : using machine learning

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Analys och partiella differentialekvationer

    Författare :Niklas Norinder; [2023]
    Nyckelord :Semiconductors; OLED; machine learning; vapor deposition; sublimation; molecular property prediction; regression; ensemble learning; deep learning;

    Sammanfattning : Organic light-emitting diodes (OLED) are and have been the future of display technology for a minute. Looking back, display technology has moved from cathode-ray tube displays (CRTs) to liquid crystal displays (LCDs). Whereas CRT displays were clunky and had quite high powerconsumption, LCDs were thinner, lighter and consumed less energy. LÄS MER

  5. 9. Freestanding graphite cathode with graphene additive for aluminum dual-ion batteries

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Adam Rosvall; [2023]
    Nyckelord :Aluminum ion batteries; Dual-ion batteries; Graphite; Graphene; Ionic liquid; Phase inversion method;

    Sammanfattning : In today’s fast adjustment to renewable energy, new battery technologies are needed to meetthe ever-growing demands of energy storage. Cheaper and easier to produce materials areneeded, as well as materials with a lower environmental impact. LÄS MER

  7. 10. A method development and complete validation of coin half-cell test procedure

    Master-uppsats, KTH/Kemiteknik

    Författare :Prasad Korde; [2022]
    Nyckelord :Cathode; Validation; Gage R and R; Six Sigma; Impedance spectroscopy; katod; validering; Gauge R och R; sex sigma; impedansspektroskopi;

    Sammanfattning : ”Coin cell”-tillverkningen täcker hela processen från NMC-pulver till faktisk cell- och prestandautvärdering genom att cykla celler. Nydanande utveckling av elektrodmaterialen är nyckeln till att öka energitätheten hos litium-jon/metall-batterier för elfordon och nätlagring. LÄS MER
