General description

Lithium hydroxide (LiOH)- anhydrous, 99.9% trace metal basis is a white powder highly soluble in water. Lithium hydroxide is a strong base and can react with acids to form lithium salts and water. Its properties make it useful in a wide range of applications, including battery technology, chemical synthesis, and industrial processes.

Application

Lithium hydroxide (LiOH)- anhydrous, 99.9% trace metal basis has numerous applications across various fields. Its primary use is in battery technology, where it plays a critical role in the production of cathode materials for lithium-ion batteries; particularly lithium cobalt oxide (LiCoO2) and lithium nickel cobalt manganese oxide (LiNiMnCoO2). It enhances the electrochemical performance and stability of these batteries. It is very useful in research areas of next-generation batteries, including lithium-sulfur and solid-state batteries to enhance energy density and extend battery lifespan. LiOH is used as a strong base in various chemical syntheses, facilitating reactions that require alkaline conditions. In the production of ceramics and glass, LiOH is used as a flux to lower the melting point of the raw materials and as an additive to improve the properties of ceramic glazes, such as durability and thermal resistance. LiOH is utilized in CO2 scrubbers to absorb carbon dioxide from the air. This application is particularly important in closed environments such as submarines and spacecraft, where maintaining breathable air is critical.[1][2][3]

Features and Benefits

  • Lithium hydroxide (LiOH)- anhydrous is designed for high-end research applications with stringent control of water content and trace metal impurities.
  • Lower content of trace metals especially, B, Ca, Al, Sr, K, and Na contribute to enhanced performance.
