Functional materials


Sustainable materials for chemical and electrochemical energy storage

Sustainable technologies for energy storage such as batteries, hydrogen storage, thermal storage or power-to-X solutions are dependent on advanced functional materials. Dwindling resources and increased focus on sustainability put new requirements on the functional materials.


The transition from fossil-fuel based energy towards renewable energy technologies have brought a strong urge for energy storage materials offering efficient, long-lived, safe and environmentally benign energy storage. This task requires advanced materials, and their development entails detailed understanding of the chemical and physical properties over multiple length-scales, i.e. form the atomic to the micron scale. Furthermore, to truly offer sustainable energy storage solutions, the functional materials themselves must also be sustainable. This set new requirements for the material design in terms on the abundancy of the required resources, the environmental impact of the material production and the potential for material recycling and disposal within a frame of circular economy. 

This symposium will bring together various fields within energy storage materials, e.g. batteries, hydrogen storage, thermal storage and power-to-X solutions. The symposium will span theoretical modeling, material preparation and recycling routes, structural characterization, property analysis and device fabrication. The overarching focus will be on material sustainability from cradle to grave and hereunder routes for material recycling.   

The proposed symposium is highly interdisciplinary and aspires to bring together ambitious young and established scientists from around the world to not only present the latest advances of the intense worldwide research but also exchange ideas as well as identify major challenges and hot-topics for future developments towards efficient solutions. We envision that bringing together researcher across the field of energy storage material will seed new research directions.

Hot topics to be covered by the symposium:

  • Environmentally benign battery materials
  • Post-lithium ion battery technologies
  • Flow-batteries
  • Hydrogen storage
  • Thermal energy storage
  • Materials for power-to-x technologies
  • Supercapacitors and metal-ion capacitors
  • Raw material supply / value chains
  • Advanced manufacturing of batteries
  • Recycling of batteries
  • Material regeneration/refurbishment
