Drawing on its long-standing experience in the field of material synthesis, and a close collaboration between the partner institutes, the Fraunhofer Battery Alliance develops innovative electrode materials and also offers the possibility to further develop these materials for use in industrial products.
A central underlying technology is chemical material synthesis. Examples include the synthesis of inorganic-organic hybrid polymers (ORMOCER®e), and sol-gel or solvothermal syntheses of numerous oxidic and non-oxidic materials (e.g. TiO2, Li4Ti5O12, cathode materials for lithium-ion batteries with olivine and spinel structures). Our chemical material synthesis technologies are complemented by our know-how in particle coating (core-shell structures). The Fraunhofer Battery Alliance also has competence in the field of surface modification with functional coatings (electrode layers on porous structures, protective layers, modification of the wettability of the liquids) and the manufacture of porous structures. Material development is enhanced by cutting-edge analytical facilities. These facilities are used in the context of industrial product development and optimization. Emphasis is placed on (electro)chemical analysis, nano-analysis, damage analysis, analysis of microstructures and layers, accredited product testing (DIN EN ISO/IEC 17025 – 2005), interface and surface analysis and radiography.
