  1. 1. 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

  2. 2. Integration of Hydrogen Production via Water Electrolysis at a CHP Plant : A feasibility study

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Anton Ottosson; [2021]
    Nyckelord :Electrolyzer; Energy; CHP; Hydrogen; Feasibility; PEM; water electrolysis; Elektrolysör; Energi; CHP; Vätgas; PEM; vattenelektrolys;

    Sammanfattning : Hydrogen gas (H2), that is not produced from fossil oil or natural gas, is expected to become a cornerstone in the energy transition strategy in Europe. The recent years, technological and economic advances in the electrolyzer area, along with political and corporate support, have put H2 at the forefront of many countries’ climate change agenda.

  3. 3. Multivariate Data Analysis on (Ti,Al)N Arc-PVD coating process : MVDA of the growth parameters thickness, stress,composition, and cutting performance

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Oorganisk kemi

    Författare :Per-Olof Öqvist; [2021]
    Nyckelord :chemistry; material; coating; statistics; PLS; PCA; kemi; material; beläggning; statistik; PLS; PCA;

    Sammanfattning : This diploma work was done at Seco Tools AB (SECO) in Fagersta and aimed to evaluate the possibility to model the relationship between deposition data, deposition properties and, cutting performance of a (Ti,Al)N coating on cutting inserts by applying the Multivariate Data Analysis (MVDA) modeling technique Partial Least Squares Projection to Latent Structures Modeling (PLS). Cathodic Arc Deposition (Arc-PVD) was the PVD technique focused on this study. LÄS MER

  4. 4. Ventilering av brännbara gaser vid batteribränder

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Nyckelord :Lithium-ion batteries; thermal runaway; energy storage; battery storage; ventilation; explosion; explosion hazard.; Litiumjonbatterier; termisk rusning; energilager; batterilager; ventilation; explosion; explosionsrisk.;

    Sammanfattning : The use of lithium-ion batteries is something that is becoming more common in today’s society. They are found in a variety of electronic equipment such as mobile phones, laptops and tools. Several incidents have been reported due to lithium-ion batteries ending up in a state called thermal runaway. LÄS MER

  5. 5. A NUMERICAL MODEL OF HEAT- AND MASS TRANSFER IN POLYMER ELECTROLYTE FUEL CELLS : A two-dimensional 1+1D approach to solve the steady-state temperature- and mass- distributions

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens högskola/Framtidens energi
