1. Lithium-ion Behaviour in Hard Carbon Anodes: Insights from 7Li NMR Spectroscopy
Master-uppsats, KTH/KemiSammanfattning : Litiumjonbatterier (LIB) är viktiga komponenter i dagens teknologi och används för att driva en mängd olika elektroniska system, allt från datorer och mobiltelefoner till bilar och flygplan. Eftersom efterfrågan på effektiv energilagring fortsätter att växa finns ett fortsatt behov för forskning och utveckling inom området. LÄS MER
2. Developing an Environmentally Friendly Approach for Ash Removal in Hard Carbon Anodes
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Hard carbon is regarded as one of the most promising anode materials for sodium-ion battery. However, the ash content of the hard carbon anode inherited from the precursor have several negative impacts on the electrochemical performance of hard carbon. LÄS MER
3. Numerical Design of an Extremely High Temperature Thermochemical Reactor for Converting Biochar to Hard Carbon
Master-uppsats, KTH/Kraft- och värmeteknologiSammanfattning : Hard carbon is now a popular choice for the anode material in sodium-ion batteries. Converting biochar to produce hard carbon is considered carbon neutral and of great interest since it reduces the environmental impacts of biomass waste. LÄS MER
4. Techno-economic Analysis of Biomass Conversion to Hard Carbon Materials
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Hard carbon is an important material for future fossil-free transport systems, as it is a popular choice for the production of anodes for sodium-ion batteries. Biomass is a popular carbonaceous raw material for making hard carbon. LÄS MER
5. Binder Migration in Double Pressed Drill Bit Inserts
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysikSammanfattning : It is possible to produce functionally graded cemented carbides on a large scale by double pressing. Being able to predict the binder migration in WC-Co cemented carbides during the sintering is essential to the design of such cemented carbides. The cobalt content is one of the main factors determining the hardness gradient. LÄS MER
