General description

Aluminum chloride is a strong Lewis acid and a major industrial catalyst. It is also used as a dopant/catalyst modifier to fabricate battery materials and solar cells.

Application

Aluminum chloride can be used:
  • To prepare cost-effective ionic liquid electrolyte for high performance aluminum ion battery.
  • To fabricate modified SnO2 triple layered photoanode for dye sensitized solar cells. This leads to suppression of electron recombination and five-fold enhancement of efficiency.
  • As a precursor to synthesize CsPbCl3 perovskite nanocrystals for bright white light-emitting diodes. It improves photoluminescence quantum yield.

Features and Benefits

  • High purity with trace metal analysis (=< 15 ppm) makes suitable for batteries.
  • High water solubility
  • Stable under battery operation conditions

The vapor-phase co-reductions with other metal halides by hydrogen results in finely divided intermetallics with applications as structural materials or compounds with useful thermoelectric, magnetic, and oxidation-resistance properties. Aluminum nitride can be synthesized from the elemnts with AlCl3 added to help facilitate crystallization.
