1. Mesoporous Titania for High Rate Electrochemical Energy Storage
Sammanfattning : Mesoporous titanium oxides are increasingly attracting interest as potential candidates for fast electrochemical energy storage. In this thesis, mesoporous titania of different polymorphs have been evaluated in relation to their ability to reversibly store Li+ ions inside their structure. LÄS MER
2. Novel electrolytes for next-generation hybrid supercapacitors - Investigating the interaction between electrolyte and electrode
Sammanfattning : The storage of electrical energy is of outmost importance in today’s society, ranging from cell phones to large scale energy storage of intermittent electricity sources. Batteries, that are most commonly used, struggle with low power density and limited cycle lifetime. LÄS MER
3. Biohybrid Polymer Electrodes for Renewable Energy Storage
Sammanfattning : Daily and seasonally fluctuating energy supply and demand requires adequate energy storage solutions. In recent years electrochemical supercapacitors have attracted considerable attention due to their ability to both store and deliver electrical energy efficiently. LÄS MER
4. Modelling and Experimental Investigation of the Dynamics in Polymer Electrolyte Fuel Cells
Sammanfattning : In polymer electrolyte fuel cells (PEFC) chemical energy, in for example hydrogen, is converted by an electrochemical process into electrical energy. The PEFC has a working temperature generally below 100 °C. Under these conditions water management and transport of oxygen to the cathode are the parameters limiting the performance of the PEFC.
