  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

    University essay from KTH/Mekatronik

    Author : Behnam Yosef Nezhad Arya; [2021]
    Keywords : 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.;

    Abstract : 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. READ MORE

  2. 2. A DMAIC based framework to conduct Measurement System Analysis : A case study at Northvolt AB

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Anshuman Manickam Vinoth; [2021]
    Keywords : ;

    Abstract : The aim of the project was to develop a framework for the execution of a Measurement System Analysis (MSA) which would help determine capability of a measurement system. The strategy behind carrying out this thesis has been to draft a framework which is based on the Define, Measure, Analyze, Improve, Control (DMAIC) model for a Measurement System Analysis (MSA) which would enable to gain a better understanding of the capability of measurement instruments that are used to control the quality of production processes of lithium-ion batteries.

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

    University essay from KTH/Kemiteknik

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

    Abstract : 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. READ MORE

  4. 4. Optimizing Control Algorithm for Indirect Liquid ThermalManagement of Batteries : A Study Executed at Northvolt

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mantas Petrosius; [2021]
    Keywords : ;

    Abstract : The vast expansion of intermittent sustainable energy generation has favoured a gradual adoption of lithium-ion batteries in various industrial and automotive applications. Despite its many inherent merits, this storage technology is very vulnerable to temperature variations: the performance and lifespan of LIBs are substantially influenced by their load cycles, thermal behaviours, and operating temperature range.

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

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

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

    Abstract : 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. READ MORE
