Integrated multi-scale system simulation and sustainability assessment of primary and circular raw material supply chains for lithium-ion batteries

Acronym: SIMTEGRAL

The overall objective of the SIMTEGRAL project is to develop and experimentally validate physically based multiscale simulation models of the most important processes for primary and secondary raw material production for Li-ion batteries. These detailed models will be linked together using a flowsheet simulation, which will then be integrated within the IC-LCE approach. Based on this, a techno-economic and social as well as life cycle assessment will be performed to gain insights for the design of sustainable value chains.

Durable and Efficient Compound Electrodes for Hydrogen Generation in PEM Electrolysis

Acronym: DECoH

The DECoH project aims to connect the fundamental understanding and the materials development of durable and efficient electrodes for acidic proton exchange membrane water electrolysers (PEMWE). The participating partners address research and development on several levels: Kyoto University will focus on the development of novel, low noble metal catalysts for the oxygen-evolving electrode. Eisenhuth GmbH & Co. KG will manufacture novel composite bipolar plates from customized materials designed and supplied by TOHO Titanium Co., Ltd. and will also produce conductive coatings for electrodes of the oxygen-developing half-cell side. TOHO Titanium Co., Ltd. will design and develop Ti-based porous transport layers that ensure efficient mass transfer with minimal degradation and performance losses. TU Braunschweig will evaluate the fabricated catalysts and components in lab-scale electrochemical test cells / electrolyzers and with mathematical models / simulations to derive guidelines for optimizing the performance, stability and efficiency of the electrodes, creating a feedback loop for the project partners.

Rechargeable zinc-manganese battery with pH neutral electrolyte

Acronym: ZiMaBat

The goal of the "ZiMaBat" project is the first demonstration of a rechargeable zinc-manganese battery (ZMB) in neutral to slightly acidic electrolyte with at least 50 charge/discharge cycles in AA format. The rechargeable ZMB is expected to achieve an energy density comparable to that of established technologies such as lead/gel, NiCd and NiMH. 
To this end, the dendrite growth at the anode will be characterized electrochemically and optically as a function of current density in the InES subproject. Subsequently, the dendrite growth will be inhibited by additives and coatings of the anode as well as by the use of different deposition techniques.
By combining expertise in zinc and manganese chemistry, separator, battery construction and recycling, and with the help of an accompanying LCA study, an environmentally friendly, non-flammable, easily recyclable energy or power round cell with different electrode design will be developed. The consortium covers the entire value chain and thus secures recycling opportunities for Germany as a business location. 
The project is being carried out jointly with VARTA Consumer Batteries, ACCUREC Recycling, EurA, the DECHEMA Research Institute, GASKATEL, Grillo-Werke and the University of Duisburg-Essen. Freudenberg Performance Materials is involved in the project as an associated partner.

DaLion 4.0 - Data mining as the basis of cyber-physical systems in lithium-ion battery cell production

Acronym: DaLion 4.0

The project "DaLion - 4.0" aims to map battery cell production in cyber-physical systems, which represent the essential core content of Industry 4.0, through an overarching approach. Thematically, different, overarching fields of action are being researched in the project. Control-capable models are being developed in the sense of cyber-physical systems that are suitable for the planning and targeted control of battery cell production. In order to increase the industrial applicability of the results, suitable quality management strategies will be developed, including in the context of improved tracking & tracing and the definition of quality gates.

Validation Experiments for a Digital Toolbox for H2 Production

Acronym: VETO-H2

The VETO-H2 project aims to complement the DiTo-H2 project, which is already running in cooperation with Strathclyde University in Scotland, with experimental investigations and to strengthen and further expand the freshly launched international collaboration. In this context, questions from the field of green hydrogen production by means of high-temperature electrolysis will be investigated. VETO-H2 will now use experimental analyses to parameterize and validate the models to be developed in DiTo-H2. For this purpose, exemplary ionic conductor materials of the Scottish partner will be exchanged and characterized.
