Cerenergy® – "Welcome to the post-lithium era!"
The transition to a sustainable energy supply is one of the central tasks in the 21st century. Fraunhofer IKTS makes a contribution to this. The ceramic high-temperature battery cerenergy® for stationary energy storage will be shown as a compact battery module. It is currently the cheapest and safest battery in the world, as it is based exclusively on harmless and readily available raw materials such as nickel, aluminium and common salt. With an energy density comparable to that of Li-ion batteries, their system costs amount to less than 300 Euro/kWh.

Fascination high-tech ceramics
With their extraordinary range of properties, ceramics are problem solvers in a wide variety of applications. Where conventional materials reach their limits, ceramics ensure more efficient processes, more reliable plant operation and more sustainable products. The test procedures developed at the institute also contribute to quality assurance.
Porous ceramics for safe melting metallurgical processes
Ceramic foams can be used in many different ways. Due to the combination of their extraordinary properties, such as their high temperature resistance and the type of pore morphology, Fraunhofer IKTS ceramic foams are predestined for use as filters, catalyst supports, burners, reformers, solar receivers, heating elements or as bone replacement materials. For the first time, IKTS scientists present an active safety device for melting metallurgy. A new type of gas-permeable porous ceramic stabilizes deflection and guide rollers in hot-dip systems. Gases that expand thermally when the rollers are lowered into the hot melt are dissipated through the microporosity of the ceramic. Overpressure, which up to now often led to the rollers bursting, is prevented. The pores are also so fine that the melt cannot flow in, and reliable plant operation is guaranteed. A fixture developed at IKTS ensures that the ceramic is sealed in the rollers.
Complex microreactors for optimized mixing and reaction processes
With new additive manufacturing technologies, complex geometries can be produced quickly and economically that cannot be achieved with any other shaping process to date. On display are 3D-printed ceramic components with complex internal structures that optimize mixing and reaction processes in the chemical industry, for example – in the smallest of spaces. Research is currently focused on developing multimaterial components or integrating additional electrical, sensory or fluidic functions. This makes it possible to create new combinations of properties in components.
Surface refinement of lightweight components with ceramics
Energy-efficient lightweight construction with carbon fiber- or glass fiber-reinforced plastics (CFRP, GFRP) is of increasing importance for mechanical engineering. CFRP or GFRP components are high-strength and very light, but less resistant to chemical and tribological stress. Ceramic coatings can significantly improve the surface resistance and quality of CFRP/GFRP parts, for example with regard to wear protection, non-stick effect or insulation behavior. At Hannover Messe, Fraunhofer IKTS will be showing CFRP and GFRP components that have been refined by atmospheric plasma spraying with various layers. Protective coating can, for example, increase the service life of components by a factor of 2 to 100, depending on the wear load.
Closing the loop from waste water to service water
Water is indispensable for both food and means of production in agriculture and industry. Wastewater must therefore be cleaned as efficiently as possible from salts, color pigments or pharmaceutical residues. Ceramic membranes make this possible. A variety of membrane-coated pipe geometries will be shown, with which up to 200 Dalton small molecules can be separated from liquids. The pilot plants equipped by IKTS with a membrane area of several hundred square meters demonstrate the economic use of this efficient and sustainable technology.
Diamond- and transparent ceramics for extreme conditions
A casting process developed at IKTS allows extremely wear- and corrosion-resistant components made of SiC-bonded diamond materials to be produced cost-effectively. The components shown on the booth are predicted to be maintenance-free for up to 30 years in use, e.g. in pumps.
The transparent ceramic developed at Fraunhofer IKTS is also suitable for use under extreme conditions and high pressure. In combination with glass, it offers a higher level of protection and weight and area saving of more than 30 % compared to conventional bullet-proof glass systems. Due to its numerous advantages, it can be used in machine and plant construction, medical technology, optical applications and in the fields of lighting or architecture, among others.
Novel glass heating elements
The powder technology route developed at Fraunhofer IKTS for the economical mass production of complex electrically conductive components made of glass-carbon offers a new generation of glass and thus a promising alternative to expensive metal-based power resistors and heating elements. The energy- and cost-efficient process allows targeted microstructuring and high edge sharpness without post-processing.
Component testing with eddy current
Eddy current processes have become a key technology in quality assurance. They function without coupling agents, there are no radiation protection requirements and they can be easily integrated into industrial production processes. With the EddyCus® device platform, Fraunhofer IKTS offers a reliable technology with which e.g. metallic materials, non/low-conductive materials such as plastics or ceramics can be tested non-destructively. This allows statements to be made on the homogeneity of infiltrations, density, inclusions or defects.

Green chemistry – fuel cells for climate-friendly gas production
Fuel cell systems no longer only generate electricity and heat. Researchers at Fraunhofer IKTS adapted the heart of these systems – a stack of high-temperature stable ceramic solid oxide cells – for co-electrolysis. In the electrochemical conversion step, synthesis gas is produced from a water-carbon dioxide mixture and renewable energy. Coupled with a Fischer-Tropsch reactor, CO2-neutral, high-qualtiy fuels, chemicals or waxes can thus be produced.
