Salinity, temperature, pH, and fluorescent dissolved organic matter (fDOM) measurements in surface waters within DynaCom experimental islands and saltmarsh enclosed plots at different elevation levels, Spiekeroog, Germany, 2018-08 to 2022-01

Data were collected between August 2018 and January 2022 as part of the research unit DynaCom (Spatial community ecology in highly dynamic landscapes: From island biogeography to metaecosystems) of the Universities of Oldenburg, Göttingen, and Münster, the iDiv Leipzig and the Nationalpark Niedersächsisches Wattenmeer. Measurements were conducted almost bi-/monthly on experimental islands and salt marsh enclosed plots located in the back barrier tidal flat and salt marsh of the island of Spiekeroog (Germany). Field-based in situ measurements of salinity, temperature, and pH were conducted using portable hand-held instruments in groundwater (filter tubes within experimental plots) and in surface waters from a tidal channel (ITC) adjacent to the experimental islands and a tidal pond (STP) in the pioneer zone of the salt marsh. Measurements were performed and samples were taken during the day between 3 hours before and 3 hours after low tide. From August 2018 to September 2019 a HQ40D digital two-channel multi meter equipped with a pre-calibrated Intellical CDC401 field 4-pole graphite conductivity cell (Hach Lange GmbH, Germany) was used to measure temperature (°C) and salinity (psu). The same device was used for pH measurements with an Intellical PHC101 field low maintenance gel filled pH electrode (Hach Lange GmbH, Germany). The pH electrode was calibrated before each fieldwork using single-use pH buffer solutions (pH 4.01, 7.00, 10.01, Hach Lange GmbH, Germany). Since October 2019, salinity and temperature were measured using a Multi 3510 IDS SET 4 handheld device equipped with a TetraCon® 925/LV 4-Pol-IDS conductivity electrode with graphite cells (WTW, Xylem Analytics Germany GmbH, Germany). Fluorescent dissolved organic matter (FDOM, ppb QSE) was measured using an AquaFluor Modell 80000-010 for UV-420 (Turner Designs Inc., USA), pre-calibrated in the laboratory. For this, water samples were taken from the field to a nearby mobile central field unit and were filtered within 1-2 hours after sampling using 25 mm Nuclepore syringe filters (0.2 µm pore size) directly into sample-pre-rinsed measurement cuvettes. Data quality control (QC) was performed using MATLAB (R2024b). Outlier detection was conducted both visually and statistically using z-score analysis (|z| > 3) per sampling campaign and plot. Each data point was assigned a Quality Control Flag (QC).

Pore-water salinity measurements in surface sediments within DynaCom experimental islands and saltmarsh enclosed plots at different elevation levels, Spiekeroog, Germany, 2023-01 to 2023-08

Data presented here were collected between January 2023 to August 2023 within the research unit DynaCom (Spatial community ecology in highly dynamic landscapes: From island biogeography to metaecosystems) of the Universities of Oldenburg, Göttingen, and Münster, the iDiv Leipzig and the Nationalpark Niedersächsisches Wattenmeer. Experimental islands and saltmarsh enclosed plots were created in the back barrier tidal flat and in the saltmarsh zone of the island of Spiekeroog. Sediment samples for the determination of pore-water salinity were taken bi-/monthly in surface sediments (0-3 cm depth) of the experimental plots. Samples were taken between 3 hours before and 3 hours after low tide. Samples were stored dark and cool (8°C) until measurement. Samples were measured in the laboratory within two months after sampling according to DIN ISO 11265:1997-06. In the laboratory, sediment samples for the determination of pore-water salinity were weighed in pre-weighed Falcon™ 50 mL conical centrifuge tubes (10 g sediment on average, depending on sand content). After one month of air-drying samples were re-weighed to determine dry weight and therefore the loss in weight. Ultrapure water was added to the tubes and were homogenized using a pestle. Salinity was measured directly in the tubes with a HQ40D Digital two channel multi meter and a pre-calibrated Intellical CDC401 field 4-poles graphite conductivity cell (Hach Lange GmbH, Germany). Post-processing of measured values were done using MATLAB (R2024b). Quality control was performed by (a) visually checks, and hence (b) the classification into quality control flags using quality check algorithms.

Hauptverbreitungsgebiete für Industrieminerale in Bayern

Als Hauptverbreitungsgebiet eines Rohstoffes wird ein großräumig unbegrenztes, geologisch heterogen aufgebautes Gebiet mit möglichen und wahrscheinlichen, bisher im Einzelnen noch nicht untersuchten oder bekannten Rohstoffvorkommen oder –lagerstätten bezeichnet. Hier dargestellt werden die Hauptverbreitungsgebiete von Industriemineralen, wie z.B. Kaolin (z.B. Füllstoff in Papierindustrie), Bentonit (z.B. Lebensmittel- und Bauindustrie), Graphit (z.B. Batterien, Bleistifte) und Kieselerde (z.B. Füllstoff in chemischer Industrie). Als Attribute angehängt sind Rohstoffgruppe, Rohstoff, Flächenkategorie und Steckbrief. Ein mit den Flächen verknüpfter Steckbrief liefert Informationen unter Anderem bezüglich der Gesteinsentstehung und -eigenschaften, Gewinnung, Verwendung und wirtschaftlicher Bedeutung des vorgestellten Rohstoffes. Als Datengrundlage für die Modellierung der Hauptverbreitungsgebiete diente die Digitale Geologische Karte 1:25.000 (dRK25), deren geologischen Einheiten den rohstoffgeologischen Einheiten zugeordnet wurden, die Karte oberflächennaher Rohstoffe (KOR200) im Maßstab 1:200.000, Flächen der Regionalplanung im Maßstab 1:100.000 (VR/VB), Rohstoffgewinnungsflächen und die Lagerstättenkarte von Bayern 1:500.000. Bitte beachten: Der vorliegende Datensatz ist nicht tagesaktuell. Der Darstellungsmaßstab ist 1:2.000.000 bis 1:120.000. (Stand 2020)

Entwicklung applikationsspezifischer Aluminium-Ionen-Batterien unter Nutzung innovativer Passiv- und Aktivmaterialien, Teilvorhaben: Entwicklung und Evaluierung innovativer Separator- und Kathodenmaterialien für applikationsspezifische Aluminium-Ionen-Batterien

Das Ziel des Fraunhofer IISB die Entwicklung neuer Kompositkathodenmaterialien, um den Anteil am kritischen Rohstoff Graphit zu verringern. Das Fraunhofer IAP zielt auf die Entwicklung von optimierten PAN-Separatoren für die Anwendung in AIB im batch-Verfahren (Größe A5-A6) sowie Skalierung der Herstellung der Separatoren auf A4 Format. Für die Durchführung von Material- und Performanceanalysen am IISB, sowie die Validierung der AIB unter Anwendungsbedingungen sollen im Anschluss die notwendigen Separatoren hergestellt werden (IAP) und zusammen mit weiteren Komponenten der Projektpartner in AIB-Pouchzellen eingesetzt werden (IISB).

Horizont Europa, Rahmenprogramm für Forschung und Innovation (2021-2027), Bringing Lithium-Ion Battery Waste tozero

tozero is committed to its mission to truly bring lithium-ion battery waste to zero. With its novel hydrometallurgical (i.e. wet chemical)battery recycling approach, it can maximize the recovery of critical raw materials (lithium, nickel, cobalt, manganese, and graphite)from both lithium-ion batteries that have reached their end of life, and scrap created during the production of new batteries.Proven on a daily basis in an operational pilot plant (commissioned in July 2023) close to Munich, Germany, tozero already now fulfillsthe recovery rates for critical raw materials from lithium-ion battery waste required by the recently enforced EU Battery Directive for2027 and 2031 and established itself as one of the leading battery recycling startups in Europe. In addition, the use of less aggressivechemicals than competitors and a mostly closed circular production process reduces the carbon footprint for batteries using tozero’srecycled material compared to batteries using mined materials by up to 80%.Considering an initial pre-seed funding of EUR 3.5mn in 2022, receiving the EIC grant would allow to significantly accelerate tozero´sscale up to industry-scale commercialization and bridge the gap for the next funding round. First, this includes additional funds fromthe EIC for the purchasing and in-house optimization of chemical reactors tailored to the innovative hydrometallurgical process oftozero. Second, it allows us to largely automate our processing and prepare for industry-scale processing. Third, it supports in thecreation of a full lifecycle assessment that is required to officially accredit our CO2e savings and helps to identify the largest lever tofurther reduce our environmental footprint. All three aspects combined allow to reach an industrial scale proof of our operations andunlock a large equity financing round in 2026.
