Lithium iodide, anhydrous, min. 98%

Product Introduction

Lithium Iodide (CAS No. 10377-51-2) is an inorganic lithium salt widely used as a lithium and iodide source in chemical synthesis, electrochemistry, battery research, analytical chemistry, and materials science.

Lithium Iodide is highly soluble in water and polar solvents and can provide both Li⁺ and I⁻ ions for chemical and electrochemical processes. Its ionic conductivity, solubility, and electrochemical properties make it useful in research involving electrolytes, lithium-based batteries, dye-sensitized solar cells, and advanced functional materials.

Mechanism / Principle

Ionic Dissociation

In suitable solvents, Lithium Iodide dissociates into lithium and iodide ions:

LiI → Li⁺ + I⁻

The lithium ion can participate in ion-conduction and lithium-ion transfer processes, while iodide can participate in redox chemistry and charge-transfer reactions.

Redox Chemistry

The I⁻/I₃⁻ redox couple is particularly important in electrochemical systems:

3I⁻ ⇌ I₃⁻ + 2e⁻

This reversible redox chemistry makes iodide-containing lithium salts useful in selected photovoltaic and electrochemical applications.
