1. Investigation of the Microstructure of Plastically Deformed Cemented Carbide
Master-uppsats, KTH/MaterialvetenskapSammanfattning : During machining operation, cemented carbide tools are exposed to high loads and temperatures, which eventually leads to plastic deformation of the tool material. The aim of this work was to investigate if the microstructures of creep deformed micro grain cemented carbides can be linked to alloying elements and mechanical properties. LÄS MER
2. Discharge and Flame Chemistry in Lithium-Ion Battery Vent Gases : Investigations using Breakdown Experiments with Laser-Based Diagnostics
Master-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionenSammanfattning : Due to the environmental impact of fossil fuels, there has been a growing interest in lithium-ion batteries for electric vehicles. However, safety concerns have arisen regarding potential fire hazards associated with the vent gases of these batteries. LÄS MER
3. Fällning av Råmaterial för Batteriåtervinning
Kandidat-uppsats, KTH/KemiteknikSammanfattning : This report explores simultaneous crystallization in multicomponent solutions to intensification of metal recovery in lithium-ion batteries. The main focus is to evaluate and compare the efficiency of sodium hydroxide and sodium carbonate as precipitating agents in recovering cobalt, nickel, manganese and lithium. LÄS MER
4. Power in the Age of the Green Energy Transition: Multinational Corporations, the State, and Cobalt in the Democratic Republic of Congo
Master-uppsats, Lunds universitet/Statsvetenskapliga institutionenSammanfattning : This thesis investigates the power balance between states and multinational corporations, and how the green energy transition impacts this balance, a connection commonly overlooked by researchers. I have sought to remedy this gap by conducting a qualitative case study of the relationship between the Democratic Republic of Congo, which holds the majority of global cobalt reserves, and major cobalt producer Glencore.
