Advantageously, the fatty acid capping, avoiding particle agglomeration upon the synthesis of the TiO2 nanoparticles, is subsequently carbonized. The resulting carbon surface layer surrounding the TiO2 nanoparticles further prevents particle agglomeration upon electrode preparation and significantly improves the electric conductivity of the thus resulting electrodes.
Commercial Opportunities: Electrodes based on this TiO2/C composite provide an improved cycling stability and an increased specific capacity compared to the use of conventional TiO2 anodes. Additionally, they show an advanced high rate capability, particularly when compared to common graphite based anodes, still mostly used in current commercial lithium-ion batteries.
Moreover, as TiO2 based anodes operate within the electrochemical stability window of conventional liquid organic electrolytes, they offer improved operating safety compared to usual graphite systems.
Further advantages of the herein presented invention are amongst others the cost-effective, fully environmentally friendly and easy up-scalable manufacturing process, which is thus easy to be integrated into an industrial production line for modern secondary batteries.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
