General description

Lithium chloride is a white crystalline highlywater-soluble compound with good ionic conductivity. It has a relatively lowmelting point, which helps in the fabrication of battery components and solid-stateelectrolytes or the use of molten lithium chloride as an electrolyte.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 chloride can be used:
  • As a precursor to fabricate protective coating on Li metal electrodes. Coated metal can be used as an advanced anode for high-charge density Li-ion batteries. LiCl enhances Li diffusion suppressing the formation of Li dendrites resulting in improved cycle stability and rate capability.
  • As a starting material to prepare humidity-tolerant and inexpensive solid electrolyte Li2ZrCl6 for Li-ion batteries.
  • As an electrolyte additive to suppress the dendrite formation and stabilization of zinc anode-based batteries. LiCl ensures higher stability during the long cycling process.

Features and Benefits

  • Highly soluble in water
  • Exhibits good ionic conductivity
  • Low melting point
  • Compatible with other battery materials like lithium metal, graphite, and transition metal oxides
