Sodium-ion batteries for large to medium-scale energy storage  

A project awarded to the College of Engineering, Swansea University




Working principle of sodium-ion batteries




Applications of Sodium-ion technology

  • Stationary Energy Storage: Off-grid and in-grid
  • Renewable Energy Storage
  • Buck-up systems (uninterrupted power supplies)
  • Automotive (e.g. ships, planes and cars)

Benefits of Sodium-ion technology

  • Availability and cost
  • Drop-in solutions
  • Energy density (similar to lithium-ion batteries LIBs)
  • Powder density (similar to LIBs)
  • Safety (improved thermal stability)
  • Cycle Life (similar to LIBs)


The overall goal of the project is to develop high performance materials assemblies of electrodes and electrolytes that are easy to synthesize, safe, non-toxic, long-lasting and cheap in order to achieve a fully functional and ready to use Na-ion battery (aqueous and organic electrolytes) targeted specifically for large-scale stationary storage, at ambient temperature.
