E-MAGIC

The aim is to develop new batteries the are more powerful, cheaper and safer than lithium-ion ones. The rechargeable magnesium battery (RMB) constitutes a paradigmatic example of such promising, alternative non-lithium energy storage systems, following pioneering efforts and breakthroughs from world-wide researchers. The potential to use metallic magnesium anodes in rechargeable batteries brings important advantages in terms of energy density, cost and safety. Magnesium batteries could pave the way for the establishment of a competitive battery cell production landscape in Europe. KIT is one of 10 scientific institutions involved in the project. Overall project coordination lies with the Spanish Fundación Cidetec. Other partners come from Israel, France, Denmark and the United Kingdom.

FestBatt-Polymere

The main objective of the subproject in the first project phase is the creation of a material basis for the critical evaluation of polymer-based electrolyte concepts for the realization of solid-lithium batteries. The work at HIU/KIT focuses on the identification, synthesis and processing of polymer and gel-polymer electrolyte systems - the latter containing low to non-volatile liquid phases such as ionic liquids - as well as their basic physicochemical and electrochemical characterization, the analysis and preliminary work for upscaling the representation of selected systems and finally their application in lithium polymer cells. In particular, the focus will be on polyethylene oxide, related derivatives and single ion conductors with the aim of obtaining improved ionic conductivities and improved electrochemical stability.

HIFI-PEFC

The aim of this project is to replace the electrolyte phosphoric acid in the HT-PEFC with proton-conducting ionic liquids. Ionic liquids based on sulfonic acids reduce the oxygen reduction kinetics significantly less compared to phosphoric acid. For this purpose, derivatives of parent compounds are to be produced and optimized with regard to conductivity, electrode kinetics and absorption in PBI membrane materials. The most promising candidates will be tested in fuel cells of technically relevant size.

HighSafe

The further increase of the specific energy or energy density of rechargeable lithium-ion batteries is a key factor for the future development of the lithium-ion battery.Batteries with a simultaneous guarantee of safety both under operating and misuse conditions and a long service life are the central challenges for the further development of energy storage systems for both automotive and stationary applications. The main objective of the joint Taiwanese-German project is to develop key materials for the next generation of high-energy lithium-ion cells that meet the requirements for energy density, lifetime, safety, sustainability and availability of raw materials. A number of new material development approaches will be pursued, which can be roughly divided into four categories: Electrode materials, additives and binders, separators and electrolytes. Material development is supported by compatibility investigations of selected material combinations in solid cells, investigations of the thermal and mechanical stability of electrodes and cells and by modelling and simulations from electrode to cell. The project is multidisciplinary and follows an integrative approach that includes all key components of the battery. The work is carried out in close cooperation between four Taiwanese and three German research groups.

In-situ IPN-SPE

In-situ polymerization of penetration networks for the construction of uniform solid state electrolytes

Compared to conventional cells, lithium-ion batteries with a solid electrolyte based on plastics offer greater safety, flexibility and lower costs and environmental impact during production. The aim of the project is to develop a simple method that allows the polymer electrolyte to be built directly in the cathode material and enables a new cell design. The uniform, ion-conducting polymer electrolyte matrix can come into close contact with the active material and assume both the function of separator and binder.

LiRichFCC

Novel Cathode Materials for Li-Ion Batteries

 

The LiRichFCC project explores an entirely new class of materials for electrochemical energy storage termed “Li-rich FCC” comprising a very high concentration of lithium in a cubic dense packed structure (FCC). The process by which energy is stored in these materials constitutes a paradigm change in the design of battery materials and involves unexpected and surprisingly effective mechanisms: instead of storing lithium ions by intercalation into a stable host, lithium ions are populating and vacating lattice sites of the material itself. This new principle allows for unprecedented energy and power density compared to other battery materials and may revolutionize the use of batteries in applications involving a need for supplying large amounts of energy and power from small spaces.

LiSuSe

The project aims to deepen the knowledge on the working mechanisms of all-solid-state batteries (SSB) and, especially, on the complex processes occurring at the solid-solid interfaces in SS lithium-sulphur batteries. The activities are particularly focused on the positive electrode (cathode). By means of advanced characterization techniques, the cathode reaction mechanism is deeply investigated and the role played by the cathode architecture carefully addressed. The main aim is to enable high S loading, which remains one of the biggest challenges to be overcome in this field.

MagSiMal

The goal in the project "MagSiMal" is: to generate a highly cycle stable and rate capable Magnesium-Sulfur-Battery, which involves cathode materials with a high content of covalently bound sulfur; to synthesize new conductive salts and electrolytes, which are stable in a broad electrochemical window and are (beside desired SEI formation) chemically and electrochemically inert. Furthermore, a strong emphasis lies on the clarification of aging mechanisms inside Mg-S-cells and their single components (anode, cathode, electrolyte) by using  post-mortem analysis techniques. Finally, the influence of different morphologies as well as surface activation of Mg-anodes on their electrochemical response is to be investigated in this project."

NEILLSBAT

The project NEILLSBAT - Nanostructured Electrodes and Ionic Liquid Electrolytes for Ultra High Energy Density Lithium Sulfur Batteries - seeks to overcome the limitations of Lithium sulfur batteries (LSB) through the development of safe high-capacity anodes based on Si and Ge nanowire heterostructure arrays and specifically designed high-capacity MOF-S cathodes in addition to safe non-flammable ionic liquid electrolytes. The ultimate goal of the research is to produce a full LSB based on these components with a specific energy of 600 Wh/kg for at least 100 cycles. In this approach the partners intend not just to synthesise these high performance electrode materials, but also to achieve a detailed understanding of their structural and chemical evolution during battery cycling, with a view to their further modification and optimisation.

ULTIMATE

The project ULTIMATE - Ultracapacitors based on innovative materials for increased energy storage capacity - has the goal to improve the energy storage and performance characteristics of Double-layer capacitors by optimizing all materials and cell components (active and inactive materials, electrolyte, electrode structure). The activities of the consortium will cover the entire value chain, from material synthesis and combination, cell construction, and adaptation of production techniques to a demonstrator system, including functional proof.

ULTIMATE is based on the experience acquired during the two BMBF predecessor projects ActivCaps and IES, as well as Skeleton's internal research in the field of carbide-based carbons (CDCs), and it combines these to develop novel components with improved properties. New, tailor-made CDCs, electrolytes based on ionic liquids (ILs), alternative and environmentally-friendly binder systems will be developed and optimized to enable a new generation of high performance and highly competitive capacitors. Furthermore, the material development is guided by simulation and prediction of elementary energy storage mechanisms. In order to be able to use the improved materials in final systems, existing production technologies will be adapted or newly developed, too.
