Sustainable electrode materials processing using flash lamp annealing

Advanced energy materials and effective manufacturing facilities of battery cells production are key parameters to overcome the economic barrier to entry into the market. This poster shows an annealing technology using the millisecond range flash lamp annealing (FLA), which takes place without preheating and can be both a vacuum and vacuum-free method. This procedure at a pilot stage is characterized by significant savings in time, energy, resource and production costs enabling to enhance the sustainability of the battery production generally. It will review, as example, the advances that are obtained using FLA on new materials for high energy density thin film electrodes based on silicon. These new materials have the capability of realizing an excellent performance of the energy storage system, e.g. of lithium ion batteries and beyond, for vehicles and stationary applications. It will be demonstrated how it is possible to develop a silicon metal electrode (SiMe) with outstanding properties with a higher capacity than the standard of the day, compatible to many variants of lithium cells, solvents free, cost-effective and capable to be integrated on roll-to- roll processing.
