The demand for high-energy-density lithium-ion batteries (LIBs) is increasing due to the growing need for portable electronic devices and electric vehicles. Within this work we show innovative approaches for current collectors and anodes, including the preparation of a light-weight current collector by metallization polymer films and the synthesis of pure silicon anodes by physical vapor deposition (PVD).From the production point of view, vacuum thin film technologies can offer process alternatives for battery anodes. Fraunhofer FEP offers several technologies and development platforms to provide innovative approaches inside the battery eco-system.
In the poster, we present recent results and possibilities for further upscaling of the process.
