Project R-3264

Soft-chemical synthesis routes towards 3 dimensional nanoarchitectures for energy generation and storage (Research)

The current project develops innovative routes for the synthesis of new materials systems with controlled nanoarchitectures in three dimensions. The multimetal oxides and phosphates selected here, have been recognized to show strong potential for improved electrochemical energy storage and generation in the most recent scientific literature. The project addresses three challenges: the synthesis of phase pure new material compositions, the formation of complex shaped powder materials and 3D ordered nanoarchitectures, and achieving of controlled interfaces in functional device environments. Wet chemical synthesis routes are capable of tackling all of these issues. Sustainable, water based routes are preferred and new possibilities for obtaining the desired nanostructures are investigated. To achieve its goals, the project will develop new precursors for the synthesis of new materials with highly valent metal ions, requiring strong control over the oxidation states, it will develop hard or soft template based approaches, and it will realize deposition of ultrathin coatings onto active material components for devices. In this way, thorough insights are obtained in the factors determining the realization of new,functional 3D materials by "soft" chemical syntheses.
