This programme aims to synthesize oriented MOF films via electrodeposition method toward highly selective and efficient electrochemical reduction of CO2. Explicitly, the electrodeposition method for synthesizing oriented MOF films and the mechanism of it are to be proposed. Various parameters of the method (including temperature, pressure, modulator and gradient fields) will be investigated. Also, the associations (1) between the orientation ...

Rechargeable lithium-based batteries are mainly used in portable devices, due to their high specific energy. In the future they will also play an important role for grid-scale storage and the electrification of vehicles. In this PhD thesis, three types of batteries were investigated in the frame of three research projects. Each type of battery has certain improved properties compared to current lithium-ion batteries.

In a first project, ...

The shortage of fossil fuels and the environmental impact of their use are continuing to exert pressure on an already stretched world energy infrastructure. The pursuit of sustainable energy storage technologies has been a worldwide research target to resolve the energy and environmental crisis. Currently, the two cutting-edge technologies of energy storage are batteries and supercapacitors. Supercapacitors are regarded as promising energy ...

The ever-increasing demand of energy, which has a very negative ecological impact on our planet and is one of the main causes of global warming, has created the necessity for a transition to a sustainable and more responsible energy and resource policy. Electrochemical energy storage systems (i.e. secondary batteries) that are capable of grid-scale storage are a valuable tool to improve the efficiency of our existing power plants, as ...

The past decades have witnessed the ever-growing research and development efforts in the field of electrochemical devices. Metal compounds and composite materials play a critical role in these devices. In order to increase the electrochemical active sites in these devices, nano-scale materials are widely explored. However, the electronic conductivity, aggregation and degradation issues of these materials impede their wide applications. Among ...

Although the highest combined energy and power density of rechargeable lithium-ion (Li-ion) batteries should make them an optimal energy storage solution for miniaturized devices, small Li-ion batteries exhibit only a fraction of the energy density of their bigger counterparts. To increase the energy density of small batteries, the superficial loading of energy-storing components needs to be increased by, for example, coating active materials ...
