Where to go with the old batteries?
What to do with the old batteries? The number of registrations for electric cars is increasing sharply. But where should the old drive batteries go? The Importeuverband Auto-Schweiz is striving for a recycling solution for the industry. Empa specialists support him. The jagged metal roller grinds its way into the battery modules, crushes the plastic frames, slits open the silver foils of the lithium polymer packs, tears everything up [...]

ISE - process for the production of high-purity aluminum
Process for the production of high-purity aluminum alcoholates SUBSTANCE: The process includes the pretreatment of aluminum compacts, followed by their dissolution in lower alcohols and the purification of the aluminum alcoholates obtained. The pretreatment is carried out by heat treatment until stable emissions are formed in the metal matrix which are incoherent with the primary solid solution. The invention relates to the production of organoaluminum compounds [...]

First development of process parameters for 3D printing of heavy metals and special materials
Initial development of process parameters for the 3D printing of heavy metals and special materials. Additive manufacturing (3D printing) has developed rapidly in recent years and is increasingly being used for small series production in industry. Due to the wide variety of fields of application, the material portfolio of the various 3D printing technologies is growing steadily. The particularly pronounced material flexibility of the powder-bed-based laser process LBM (Laser Beam Melting) [...]
