General description

Lithium iodide is widely used as an electrolyte additivein dye-sensitized solar cells and Li-S batteries, as it enables long cyclelife. It is also used as a phosphor for neutron detection.
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(LiI)can be used as an electrolyte additive:

  • To prepare biodegradable polymer electrolytes.Rice starch complexed with LiI shows enhanced ionic conductivity as theaddition of LiI increases the number of mobile charge carriers.
  • For Li-S batteries. LiIforms a protective coating on the surface of both negative and positiveelectrodes and prevents the dissolution of polysulfides on the cathode sidewhich significantly enhances cell rate performance.
It can also be used to prepare Li-basedscintillators with enhanced thermal neutron detection efficiency.

Features and Benefits

  • 10 mesh particle size provides a larger surface area for better reactivity and interaction in chemical processes, improving efficiency in energy storage and conversion.
  • 99.9% trace metals purity facilities better charge/ion transport leading to improved performances.
  • Enhances durability and Longevity of energy & electronic devices due to minimum metal impurities.
  • Low metal impurities reduce structural defects in solar cells and contribute to the formation of a stable electrolyte in batteries.
