The latest research has revealed promising results for Silicon (Si) and Germanium (Ge) as anode materials for lithium-ion batteries. Owing to their high energy capacity these two semiconductors are considered auspicious alternatives to graphite anodes. In this study, we set the goal of synthesizing a porous silicon-germanium structure over a wet chemical sol-gel approach. Here, diblock copolymer polystyrene-block-polyethylene oxide is used as the structuring agent. Real-space data as SEM and microscopy images will be discussed with reciprocal-space analysis methods as grazing-incidence x-ray scattering in small and wide-angle mode.
