1. Electrochemical Investigation of the Reaction Mechanism in Lithium-Oxygen Batteries
Sammanfattning : Lithium-oxygen batteries, also known as Lithium-air batteries, could possibly revolutionize energy storage as we know. By letting lithium react with ambient oxygen gas very large theoretical energy densities are possible. LÄS MER
2. High Bandgap FAPbBr3 Perovskite Solar Cells : Preparation, Characterization, and Application
Sammanfattning : High bandgap lead-halide perovskite solar cells (PSCs) have gained interest as top cells for tandem solar cells and photoelectrochemical applications due to their suitable energy bands. However, the PSCs have limited stability and performance, and their fabrication in a glovebox and utilization of expensive metal contacts increase the cost and limit their application. LÄS MER
3. LiNi0.5Mn1.5O4 cathodes for lithium-ion batteries : Exploring strategies for a stable electrode-electrolyte interphase
Sammanfattning : Climate change, a pressing global issue, can be partially addressed by using electric vehicles to reduce CO2 emissions. In this context, high-energy and high-power density batteries are vital. The LiNi0.5Mn1. LÄS MER
4. Novel electrode and photoelectrode materials for hydrogen production based on molecular catalysts
Sammanfattning : The PhD project focussed on the application of a cobalt tetraazamacrocyclic complex, in the literature commonly referred to as [Co(CR)Cl2]+ as a molecular catalyst for the hydrogen evolution reaction (HER). This was within the broader scope of the EU MSCA H2020 ITN ‘eSCALED’ project, which primarily aimed to create artificial leaf devices for the storage of solar energy in chemical fuels and, as part of this, sought the development of novel bio-inspired and scalable materials.

5. Operando Characterisation of Lithium–Sulfur Batteries
Sammanfattning : Lithium–sulfur (Li–S) batteries have been under the spotlight of research on electrochemical energy storage systems, primarily owing to their high theoretical specific energy (2552 Wh kg-1). So far, Li–S cells on the market have presented a specific energy of 400 Wh kg-1, which is superior to many commercial alternatives, but far below the theoretical value. LÄS MER
