General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Click here for more information.

Application

Lithium iodide can be used:


  • As a precursor to synthesize polymer-based electrolytes for dye-sensitized solar cell(DSSC) application via solution casting method.[1]
  • Li2S-P2S5-LiI crystalline inorganic-organic hybrid electrolytes with high ionic conductivity via liquid-phase synthesis for all solid-state batteries.[2]
  • As a redox mediator for Lithium–oxygen (Li–O2) batteries. It can facilitate redox reactions by shuttling charge carriers between electrodes, enabling efficient energy conversion.[3]

Features and Benefits

  • Excellent ionic conductivity at elevated temperature
  • Good thermal stability
  • Compatible with lithium-based battery materials.
