Miniaturized Power Supplies: Research on Micro-fluidic Rechargeable Batteries
The micro-fluidic batteries have great potential to be employed as the standard power source in MEMS and LOC devices. Also, it is attractive to number up these devices to obtain power systems for conversion and storage of larger amount of energy, e.g. combined with photovoltaic cells or wind turbines as an autonomous (remote) energy supply system. The potential of this project include sustainability and environmental considerations. Miniaturized rechargeable batteries decrease the need for raw material. The enhanced lifetime as well as the less waste generated by production, effects positively the entire cradle-to-grave cycle of small scale power sources.
The student will be involved with the identification of the physical and chemical phenomena occuring in the micro-fluidic battery on the basis of a literature research. After the identification of the relevant phenomena, the governing equations for electrolyte flow, mass transfer of species, chemical reactions, and thermodynamics/heat transfer have to be identified.
The primary goal is to set-up a simple but effective 1-D model of the phenomena within the micro-fluidic battery. The model should reflect the essential physicochemical features with a low level-of-detail and should be solved with either MATLAB or a commercial CFD code.
