High-efficiency electrodes with ultralight fabric-based current collectors for li-ion batteries

Lithium-ion batteries (LIB) are indispensable key components for electro mobility and the success of the energy transition. They offer high energy density and high cycle stability. Eight partners from industry and science are developing technologies and components in the funded project "revoLect" (funding reference: 03ETE041) in order to be able to produce resource-saving and more efficient LIBs. The project is pursuing two key innovations: the replacement of the usual metal foils with a metallized fabric structure and the use of silicon as anode material.

Fraunhofer FEP: Retrofittable electrochromic films for windows and glass facades control light incidence

Controlling light and heat radiation through windows and glass facades at the push of a button, saving energy and still maintaining a clear view? Switchable electrochromic films that turn dark but remain transparent are expected to make this possible in the future.

Fraunhofer FEP: Ultra-low power OLED microdisplays are ready for transfer to industry

OLED microdisplays researched and developed at the Dresden Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP have already been offered for several years as evaluation kits for potential exploitation partners. In addition to the design of application- and customer-specific microdisplay chips made possible by means of integrated circuit design, the industry-compatible, standardised manufacturing process technology development up to testing and characterisation methods plays an important role. For the latter, a 64-device microdisplay test unit for characterisation upon delivery or/and receipt of goods by customers will now be presented for the first time at embedded world 2023 (14-15 March in Nuremberg, Germany), at the Fraunhofer joint booth (Hall 4, No. 422).
