General description

Lithium perchlorate is a white salt that easily dissolves in water. It is commonly employed as an electrolytic salt in batteries due to its excellent electrical impedance, conductivity, hygroscopicity, and anodic stability properties. These characteristics are crucial for its role in battery applications. In addition, it is as a strong oxidizing agent and hence is used as an oxidizer in solid rocket propellants and organic reactions.
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 perchlorate can be used:
  • As a precursor to prepare solid polymer electrolytes for rechargeable Li-ion batteries.
  • As an oxidizer to prepare polymer-based solid propellants.
  • To fabricate cobalt sulfide (CoS)-based counter electrode for dye-sensitized solar cells(DSSC).
Our Lithium perchlorate, with a 99.99% trace metals basis, possesses specific specifications that make it ideal for Lithium-ion batteries. It has low levels of anion traces such as chloride (Cl-): ≤0.003%and sulfate (SO42-): ≤0.001%. Additionally, it contains less than 5 ppm of heavy metals, further enhancing its suitability as an electrolytic salt for Lithium-ion batteries.
