At present, massive research is being conducted into a successor technology for the classic lithium-ion batteries. One of the most promising approaches for future energy storage systems is the so-called solid state battery, as ionically conductive solids are used instead of liquid electrolytes. This substitution is expected to result in considerably higher energy densities, while the use of a non-flammable solid will also increase safety. This new technology, however, brings new challenges for the manufacturing process. For example, an energy-intensive furnace sintering process is currently used for the layered composite production of cathode and solid electrolyte.
Within the scope of several student projects the laser sintering of a solid material for future solid state batteries is to be evaluated. Thereby, the laser-material interaction is analyzed by means of different laser parameters and subsequently evaluated by different characterization methods (optical, thermal, mechanical).
Literature research on the current state of research:
