The HIU research group Solid State Chemistry is an interdisciplinary group in which chemists, physicists, and engineers are active. The focus of their research is on the battery systems to come after the lithium-ion ones, referred to simply as "batteries beyond lithium". Parallel to this work, new and alternative approaches are being developed to overcome the obstacles to lithium-free batteries.
Although lithium-ion batteries are widely used, their storage capacity is limited. In the future, battery systems with higher energy density will be needed, in particular for electromobility. These batteries will need the capacity to store more electrical energy at a lower weight. Lithium-free batteries will also be needed in the future that possess a markedly higher storage capacity and improved safety features.
This work should lay the cornerstone for innovative and more powerful batteries. One object of study is the potential of various battery materials to raise the energy density of today’s battery systems. Current examples of this are the fluoride-ion and chloride-ion batteries, both of which have the potential for significantly exceeding the storage capacity of the lithium-ion battery.
Another object of current research is the magnesium battery, which also exhibits a relatively high energy density. This research group is also involved in the development of active materials (e.g., electrode materials). One feature that has priority here is the issue of safety.
New anode and cathode materials made of nanocomposites are also being developed and tested in order to make electrochemical energy storage units more efficient.
The “Solid State Chemistry” group at the HIU contributes to various research fields in POLiS: for Na-ion batteries, we develop cycle-resistant cathode materials based on layered oxides as well as novel, ion-conducting and water-soluble inorganic binder materials. In the area of multivalent systems such as Mg and Ca batteries, we develop new electrolytes with high ionic conductivity and stability as well as cathodes based on organic materials and sulfur cathodes. Another research field is new high-performance anodes, especially for Ca batteries, as well as protective layers and gel polymer electrolytes. In the research field of anionic systems, we expand the toolbox by developing new cathode and anode materials as well as solid-state electrolytes.
This research group is partially funded by the Deutsche Forschungsgesellschaft (DFG) through the Cluster of Excellence POLiS.
We have demonstrated the first reversibly working battery cells based on fluoride shuttle. In secondary fluoride batteries, fluoride anion acts as charge transfer ion between a metal/ metal fluoride pair where it will react with metal or evolve from metal fluoride depending on the flow of current. The theoretical capacity can be several times higher than that of conventional Lithium Ion Batteries, depending on the combination of metal and metal Fluoride.

The Cluster of Excellence POLiS investigates new battery materials and technology concepts for efficient and sustainable storage of electrical energy. The Cluster aims at developing electrode materials and electrolytes that allow for sustainable systems based on Sodium, Magnesium, Calcium, Aluminium, and Clorine ions. Major obstacles for the development and use of post-lithium systems and thus the legitimation for our research are: (1) Low ionic mobility in solids and liquids, (2) Lack of well-designed materials interfaces with suitable charge transfer properties, (3) Degradation of active materials and electrolyte, and (4) Lack of reversibility of charge- and discharge processes.
