Halogen-rich argyrodites for lithium-sulphur batteries

Image from Licence Details: Halogen-rich argyrodites for lithium-sulphur batteries

Applications:  Solid-state lithium batteries

Features Benefits
  • A novel solid-state electrolyte that can be applied in all-solid-state Lithium-Sulphur (Li-S) batteries
  • Aims to provide a lithium all-solid-state battery with high capacity and high energy density.
  • No polysulphide formation or dissolution
  • An argyrodite solid electrolyte which consists of lithium, phosphorus, sulphur, and a halogen/halogens, such as chlorine and bromine
  • Structural modifications of the argyrodites achieves higher conductivity and lower activation energy
  • Ionic conductivity of the solid electrolyte shown to be ~10 mS/cm
  • Can be used in all-solid-state Li-S cells and improve the cycle performance and rate performance, leading to higher energy density
  • Benefits from sulphur’s natural advantages while overcoming its challenge of low stability
  • Sulphur is naturally abundant leading to environmental benefits and lower cost
  • Other Li-S advantages include providing lighter-weight and safer batteries
  • Researchers have experimented with different halogen compositions and identified specific novel  compositions that are particularly advantageous
  • Initial lab tests and data acquisition completed and show great cycling and rate performance for solid-state Li-S batteries with such an electrolyte
