  1. 1. Implications of different sensor resolutions and contrast settings in a roll-to-roll process, considering the speed of the process vs identifying defects, for manufacturing green batteries : A study on the effect of light conditions on thedetection of defects in cathode foil in batteries

    Master-uppsats, KTH/Mekatronik

    Författare :Behnam Yosef Nezhad Arya; [2021]
    Nyckelord :Contrast; Surface; Resolution; Speed; Defect; Sensor; Battery; Computer vision; Roll-to-roll; Contact Image Sensor; Mechatronics; Ljusinställning; Yta; Kontrast; Resolution; Hastighet; Defekt; skada; Sensor; Batteri; Computer vision; Roll-to-roll; Contact Image Sensor; Mekatronik.;

    Sammanfattning : This Master’s thesis work is about the conditions that can affect the identification of defects in lithium-ion batteries. In lithium batteries, there are cathode and anode, which are separated with electrically insulative but ionically conductive electrolytes and separators. LÄS MER

  2. 2. Combining Smart Energy Storage with a Nordic PV Park : An explorative study of revenue-improving and cost-reducing battery services

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Amanda Bränström; Jonna Söderberg; [2021]
    Nyckelord :battery storage; energy storage; PV park; primary frequency regulation; energy arbitrage; NPV; VRE; Li-ion; service stacking;

    Sammanfattning : With global climate change as the main driver, there is an increase towards including more variable renewable energy (VRE) sources in the electricity mix. Energy production from utilizing the photovoltaic effect, or PV power, is increasing rapidly and is visioned to cover 5 – 10 % of Sweden’s electricity demand in 2040. LÄS MER

  3. 3. Investigations of the Thermal Runaway Process of a Fluorine-Free Electrolyte Li-Ion Battery Cell

    Master-uppsats, KTH/Kemiteknik

    Författare :Tamara Patranika; [2021]
    Nyckelord :Lithium-ion batteries; Electrolyte; Non-fluorinated; Thermal stability; Litiumjonbatteri; Elektrolyt; Fluorfri; Termisk stabilitet;

    Sammanfattning : Detta projekt syftar till att undersöka den termiska rusningsprocessen hos ett litiumjonbatteri med en fluorfri elektrolyt och jämföra den med en kommersiellt använd fluor-innehållande elektrolyt. Battericellerna innehöll silikon-grafit som anod och LiNi0.6Mn0.2Co0. LÄS MER

  4. 4. Tjänster och lönsamhet med ett batterilager till en solcellspark : En fallstudie om att implementera ett batterilager till Vasakronans solcellspark i Uppsala

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö; Uppsala universitet/Byggteknik och byggd miljö

    Sammanfattning : The installed capacity of electricity produced from solar power has increased over the years and will do so even further. A lot of companies are investing in so-called solar parks to create large scale electricity production from solar power. LÄS MER

  5. 5. Six Sigma for quality assurance of Lithium-ion batteries in the cell assembly process : A DMAIC field study at Northvolt

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Mani Mostafaee; [2021]
    Nyckelord :Cell assembly process; ISO 14644; Lithium-ion battery; Particle contamination; Quality Cost; Technical cleanliness; VDA 19;

    Sammanfattning : Lack of technical cleanliness and particle contaminations in Lithium-ion battery manufacturing affect the performance of batteries which are a risk for the safety and quality of the product. Therefore, part of the manufacturing process occurs inside the Clean and Dry room area to maintain technical cleanliness. LÄS MER
