Research Groups Involved

  • Focus of the Chair of Electrical Energy Systems (Prof. Michael Danzer) is the investigation of methods of efficient energy conversion and storage in general and durable and reliable applications of batteries and fuel cells in particular. Analysis and simulation of Li-batteries are key elements of the research activities.
  • The Chair of Inorganic Chemistry I (Prof. Josef Breu) focuses on hierachic structuring of solid state materials. Knowledge concerning synthesis and structuring from nm-scale to µm-scale will foster the development of innovative and safe high capacity cathode materials.
  • The Chair of Functional Materials (Prof. Ralf Moos) investigates novel materials and technologies for energy conversion. Innovative battery concepts, materials and processing methods provide a solid basis for the development of batteries within BayBatt.
  • The Chair of Physical Chemistry II (Prof. Georg Papastavrou) is specialized concerning the investigation of surfaces. Within BayBatt the focus is on scanning electrochemical microscopy. This method will now be applied on electrode materials for the first time.
  • The Chair of Electrochemical Process Engineering (Prof. Christina Roth) investigates processes and materials of electrochemical energy transformation and storrage. Spectroscopic methods for in-operande characterization as well as processes for 3D-structuring of porous electrodes (e.g. via electro-spinning) are key elements of ongoing research. Projects are concerned with manufactoring and characterization of carbon materials and porous electrodes of Li-batteries and Redox-Flow-Batteries.
  • The Professorship for Information Systems and Digital Energy Management (Prof. Jens Strüker) focuses, among other things, on the potential of digital technologies for the energy industry and their impact on a real-time energy industry and on effective climate protection. Within BayBatt, a battery management system is developed in order to increase the profitability of battery storage systems and the verifiability of electricity use. This battery management system is based on real-time CO2 pricing for electricity from the battery storage system and on flexible interaction with different energy markets.
  • The Chair of Physical Chemistry I (Prof. Markus Retsch) is profound in modeling of heat transport and its analytics e.g. via Laser Flash Analysis, Lock-in-Thermography and photo-acoustic methods. Key topics are heat transport in colloidal materials and thin films. Within BayBatt operando analyses are being developed as well as real-time methods that serve state estimation by sensor and model based self-assessment.
  • The Chair of Physical Chemistry III (Prof. Roland Marschall) combines inorganic synthesis methods with thorough physico-chemical characterization. Within BayBatt new active materials are being developed. These materials are structured in order to achieve optimized wetting behavior. In addition, detailed electrochemical and spectroscopic investigations are carried out within research cooperations.
  • The research group of Prof. Mukundan Thelakkat at the Chair of Macromolecular Chemistry I is profound in tailor made functional polymers for several applications in electronic devices. Within BayBatt novel concepts of ionic conductive polymers are used as solid electrolytes.
  • The research group of Prof. Seema Agarwal at the Chair of Macromolecular Chemistry II is profound in polymer synthesis, manufactoring and structuring of composites as well as processing methods. Within BayBatt separators are being developed by using high temperature polymer composites in order to achieve thermal and mechanical stability as well as wettability. Ionic conductivity will be improved by using Lithium ion conducting additives.
  • The Chair of Manufacturing and Remanufacturing Technology (Prof. Frank Döpper) collaborates intensivly with medium-sized businesses in the research fields of future and sustainability technologies, additive manufacturing / 3D printing, artificial intelligence, digitalization of production, machining and remanufacturing. Within BayBatt basics of the remanufacturing of battery storage systems are being investigated.
  • The Keylab Glass Technology (Prof. Thorsten Gerdes) at the Chair of Ceramic Materials Engineering combines fundamental research and application oriented development. Glass melting and processing technology for functional glasses, which enable new applications in batteries are research subjects. Research activities at BayBatt are glass-based separators that ensure security of batteries in extreme situations and that slow down cell aging due to their chemical composition. The separators are tested for different applications together with industrial partners under application-related conditions in lithium-ion batteries.
  • The focus of the chair of Inorganic Active Materials for Electrochemical Energy Storage (Prof. Matteo Bianchini) is to improve the current generation of Li-ion batteries, as well as to develop next-generation technologies such as Na-ion or solid-state batteries by designing, synthesizing and characterizing novel electrode materials. Electrode materials are the “heart” of energy storage devices and determine their performances. Improved cathode and anode materials are the key to higher-performance, longer-lasting batteries.
