Zinc-slurry formulation, cell characterization and scale up of zinc-air redox-flow battery

 Recruiting organisation: Fraunhofer Institute for Chemical Technology ICT, Germany
Subproject title: Zinc-slurry formulation, cell characterization and scale up of zinc-air redox-flow battery
Starting date: 1st April 2018 (or earlier if preferred)

Background information:

Marie Skłodowska-Curie European Training Networks (ETNs) are joint research and training projects funded by the European Union. Funding is provided for postgraduate researchers from both inside and outside Europe to carry out individual project work in a European country other than their own.

The training network “FlowCamp” is made up of 11 partners, coordinated by Fraunhofer ICT in Germany. The network will recruit a total of 15 postgraduates for project work lasting for 36 months.

Renewable energy sources like wind turbines require large-scale, stationary energy storage systems to balance out fluctuations in energy generation. FlowCamp will advance the development of one of the most promising storage systems: redox-flow batteries (RFBs). The recruited fellows will develop materials (membranes, electrodes, electrolytes, catalysts,

sealing materials) and macrohomogeneous models for three next-generation RFBs (hydrogen-bromine, organic and zinc-air systems). They will then upscale the new systems to prototype level and validate them using the cutting-edge battery testing facilities available for the prestigious German-funded RedoxWind project at Fraunhofer ICT. The new RFB technologies can be combined in energy storage systems tailored to a wide variety of application scenarios, with lower cost, longer service life and higher efficiency than conventional (e.g. Li-ion) storage devices.

Job description:

The advertised subproject will be carried out by one postgraduate (“early-stage researcher”) at Fraunhofer ICT over a period of 36 months.

The objectives of the proposed subproject are: 1) Development of flow-through reactor, 2) Investigation of the nucleation problem of the zinc oxide, 3) Investigation of the formation of ZnO dendrites on the Zn particles and the effect of adding inorganic additives such as CaO or MgO, 4) Implementation of redox mediators to prevent zinc particles from participation, 5) Optimization of cell design to avoid the electrolyte carbonation, 6) Integration of 3D printing technique in order to achieve complex cell designs without complicated production techniques, 7) Development of laboratory scale zinc-air redox-flow battery, 8) Test of developed RFB at ICT and the acquisition of data for an economic analysis.

The expected results are: 1) Uniform distribution and optimum flow of zinc slurries, 2) Avoidance of ZnO dendrite formation, the precipitation of zinc particles and the carbonation of the electrolyte, 3) Development and optimization of electrically conductive carbon composites for industrial 3D printing devices, 4) Evaluation of the developed battery components for a zinc-air system, 5) Economic analysis of RFB system.

This subproject is fully funded by the Marie Skłodowska-Curie European Training Network „FlowCamp“ (H2020-MSCA-ITN-2017). The recruited researcher will have the opportunity to work as part of an international, interdisciplinary team of 15 postgraduates, based at universities and industrial firms throughout Europe. She/he will gain a unique skill-set comprising electrochemistry, material science and cell design/ engineering, as well as an overview of different RFB technologies and their implementation at prototype level. She/he is expected to finish the project with a PhD thesis and to disseminate the results through patents (if applicable), publications in peer-reviewed journals and presentations at international conferences.


Qualifications / experience:

  • Early-stage researcher: a researcher without a PhD, who is in the first four years (full-time equivalent research experience) of her/his research career, measured from the date when she/he obtained the degree which would formally entitle her/him to embark on a doctorate.
  • Graduation in the field of chemistry, electrochemistry or related engineering fields – M.Sc. preferred.
  • Basic knowledge of electrochemical energy storage systems, batteries, inorganic additives, polymers and/or carbon based battery components.
  • Practical experience of electrochemistry lab. is a plus.
  • Basic knowledge of data analysis (i.e. OriginLab) and Microsoft Office.
  • Well-structured and autonomous working style, good organizational and communication skills.
  • Fluency in written and spoken English and German is a plus.


The applicant must not have resided or carried out her/his main activity (work, studies etc.) in Germany for more than 12 months in the past three years.
