Electrode foils play a decisive role in the production of batteries and accumulators for electric cars, smartphones, and laptops. In the case of lithium-ion batteries, for example, the coating of electrodes ensures that lithium can be stored and released again. The electrode material is applied as a thin paste to a copper or aluminum foil. As yet, this foil coating process has been taking very much time and thus has been driving up manufacturing costs. Researchers at Karlsruhe Institute of Technology (KIT) now are able to significantly increase the production speed with a new intermittent, i.e. interrupting, process. A special membrane
is used which cyclically stops and restarts the application of the coating paste.
Superconductors can transport electrical current at low temperatures, usually below 25 K (-248°C) without any losses. For operation at comparably high temperatures, ...
