1. A scalable furnace technique to grow silicon nanoparticles for high-performance Li-ion battery anodes
Sammanfattning : Lithium-ion batteries are one of the key technologies to address the global climate challenge. Higher battery capacity could also be seen as indirectly influencing the entire value chain. One way to increase capacity is to add silicon to the graphite anode, since silicon can store much more lithium ions than graphite. LÄS MER
2. Mechanical Pulp-Based Nanocellulose : Processing and applications relating to paper and paperboard, composite films, and foams
Sammanfattning : This thesis deals with processing of nanocellulose originating from pulps, with focus on mechanical pulp fibres and fines fractions. The nanocellulose materials produced within this research project were tested for different purposes ranging from strength additives in paper and paperboard products, via composite films to foam materials.

5. Low-Cost, Environmentally Friendly Electric Double-Layer Capacitors : Concept, Materials and Production
Sammanfattning : Today’s society is currently performing an exit from fossilfuel energy sources. The change to sustainable alternativesrequires inexpensive and environmentally friendly energy storagedevices. However, most current devices contain expensive,rare or toxic materials. These materials must be replaced bylow-cost, abundant, nontoxic components. LÄS MER
