Design, formation, characterization and optimization of composite electrodes for aqueous ion insertion batteries

Electrochemical batteries represent one of the most attractive alternatives for energy storage due to their wide power and energy range, excellent energy efficiencies, low environmental footprint, and high scalability. Aqueous (Na-, Li-, K-, Zn-, Al-ion) ion insertion batteries represent an attractive alternative to traditional non-aqueous Li-ion batteries. They can be based on non-scarce materials, safe, low-cost and environmentally benign. However, a significant research effort is needed in order to fully enable this technology and make it competitive with modern Li-ion systems. This effort not only encompasses the search for new materials, but also their integration into functional, efficient, robust and clean electrodes and electrochemical cells.
 
The main tasks of this project are:
  1. Design and synthesis of highly-conducting electrode composites based on phosphate framework (e.g. NASICON, pyrophosphate, mixed phosphate) materials.
  2. Integration and formation of functional electrodes by searching and designing appropriate water-insoluble and hydrophilic polymeric binders and carbonaceous additives.
  3. Characterization and optimization of functional electrode assemblies in terms of mixing and casting processes, current collector preparation, drying and porosity control by mechanical, structural, spectroscopic, morphological and electrochemical
