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

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

    Författare :Anshuman Manickam Vinoth; [2021]
    Nyckelord :;

    Sammanfattning : 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.

  2. 2. 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

  3. 3. 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
