Publication number: 20250029975Abstract: The invention relates to a method for solvent-free production of an electrode. By means of the method it is possible to produce an electrode which has high mechanical stability and which provides a high specific capacitance. The method also enables the production of an electrode which can be used as an anode in a lithium-ion battery, without giving rise to unstable operation with undesirable and irreversible degradation reactions. An electrode is also provided, which has the above-mentioned advantages. In addition, uses of the electrode according to the invention are proposed.Type: ApplicationFiled: August 17, 2022Publication date: January 23, 2025Applicants: FRAUNHOFER-GESELLSCHAFT ZUR FÖRDERUNG DER ANGEWANDTEN FORSCHUNG E.V., TECHNISCHE UNIVERSITÄT DRESDENInventors: Florian SCHMIDT, Susanne DÖRFLER, Holger ALTHUES, Stefan KASKEL, Benjamin SCHUMM, Sebastian TSCHÖKE
