Powerful, durable, safe, and low production costs: batteries Made in Germany could soon secure a place among the best in the world. This will be realized by including advanced approaches to quality assurance and analytics in production, which are now being developed and tested at Karlsruhe Institute of Technology (KIT). The activities in the AQua battery research cluster are part of the Battery research factory initiated by the Federal Ministry of Education and Research (BMBF).

Powerful, durable, and safe: these properties, combined with a low price, could soon secure batteries “Made in Germany” a place among the best in the world. This will be realized by including advanced approaches to quality assurance and analytics in production, which are now being developed and tested at the Karlsruhe Institute of Technology (KIT). The activities in the AQua battery research cluster are carried out in close cooperation with research partners in the “Battery research factory” initiated by the Federal Ministry of Education and Research (BMBF).

Tungsten has the highest melting point of all metals, 3,422 degrees Celsius. This makes the material ideal for use at high temperatures in e.g. space rocket nozzles, heating elements of high-temperature furnaces, or the fusion reactor. However, the metal is highly brittle and, hence, difficult to process. Researchers of Karlsruhe Institute of Technology (KIT) have developed an innovative approach to making this brittle material soft. To process tungsten, they have determined new process parameters for electron beam melting.
Tungsten is a metal with very attractive properties: It is corrosion-resistant and as heavy as gold. In the form of tungsten carbide, it is as hard as diamond. And it has the highest melting point of all metals, 3,422 degrees Celsius. However, the metal is highly brittle at room temperature. Due to its properties, tungsten is dif
