Metal-Organic-Framework-based Electrolytes for Solid-state Batteries

Unmet Need: Improved electrolytes for solid-state batteries

Solid-state batteries show a great potential for practical application in energy storage devices. However, the ionic conductivity and interfacial properties of solid -state electrolytes still need to be improved for the wide commercialization of solid-state batteries due to insufficient ionic conductivity, narrow electrochemical stability window, poor mechanical robustness, poor compatibility with metal anodes, and instability under ambient atmosphere.


The Technology: Metal–organic frameworks based solid-state electrolytes

WSU researchers present metal–organic framework (MOF) based solid-state electrolytes. These electrolytes are prepared by infiltrating metal salts in nano-sized metal-organic frameworks, followed by mixing with binder.  



  • Manufacturing of energy storage devices.


  • Fast metal-ion conduction of the electrolytes, such as lithium, sodium, and potassium ions.
  • Improved metal-ion transference number.
  • Improved stability and compatibility with metal anodes.
