  1. 31. 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.

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Lucas Van Genechten; [2023]
    Nyckelord :Recycling; lithium-ion battery; deep discharging; external short-circuit; internal pressure; thermal stability; Electrochemical impedance spectroscopy; Återvinning; litiumjonbatteri; djupurladdning; extern kortslutning; internt tryck; termisk stabilitet; electrochemical impedance spectroscopy;

    Sammanfattning : In response to the present and projected growth of the EV industry, the development of a large-scale, reliable and efficient lithium-ion battery recycling sector is vital to ensure circularity of the embedded valuable metals and ensure overall sustainability of the technology. One of the main recycling procedures under development is based on hydrometallurgy. LÄS MER

  4. 33. 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

  5. 34. Electrochemical Characterisation of LiFePO4-Coated Carbon Fibres: A Comparative Electrochemical Analysis of Three Coating Methods

    Master-uppsats, KTH/Tillämpad elektrokemi

    Författare :Julia Szecsödy; [2023]
    Nyckelord :Structural battery composite; Carbon fibres; Lithium-ion battery; Electrophoretic deposition; Spray coating; Powder impregnation; Strukturella batteri kompositer; Kolfiber; Litiumjon batteri; Elektroforetisk beläggning; Sprutbeläggning; Pulverimpregnering;

    Sammanfattning : Kolfiber CF kan användas som positiv elektrod i strukturella batterier om de beläggs med ett aktivt material, såsom litiumjärnfosfat LFP. Fördelen med att använda kolfibrer som elektroder är att de samtidigt kan bära mekanisk belastning och lagra elektrisk energi. Det finns flera tekniker för att belägga kolfibrerna. LÄS MER

  7. 35. Sustainability and circularity metrics for EV batteries: Enabling circular economy strategy decision making and value communication

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :Gunjan Kolhe; [2023]
    Nyckelord :Sustainability metrics; Circularity metrics; LIB CE strategies; Second life battery energy storage system; Product service system; Earth and Environmental Sciences;

    Sammanfattning : The increasing focus on lithium-ion batteries (LIBs) in the context of electrification of transport sector has raised concerns about their high costs, resource and energy demands, environmental impact, and social supply chain risks. To address these challenges and maximize the value of LIBs throughout their lifecycle, circular economy (CE) strategies, such as reusing and repurposing, are being explored. LÄS MER
