The increasing energy demand of mankind, the consumption of fossil fuels and the climate-influencing emissions of greenhouse gases made it necessary to rethink energy production. Electric energy from renewable sources in most cases is depending on climatic or environmatal conditions as for example the presence of wind, sun or floating water. For this reason, it is as necessary to strive for highest efficiency in converting of photonic or mechanic energy into electricity as to also significantly increase efficiency and capacity in storage. Storing high loads of electricity in smallest possible storage devices goes along with high energy densities implying security considerations to avoid fire and explosion. To safely meet given requirements, compliance of surface geometries and structures is indispensable and requires constant monitoring throughout the manufacturing process.
