General description

Lithium sulfate, anhydrous, free-flowing, Redi-Dri™(99.5% trace metals basis) is a high-purity, moisture-resistant formulation designed for applications that demand consistent and precise material properties. Our Lithium sulfate, anhydrous, free-flowing, is packaged in the advanced Redi-Dri™ packaging, which effectively prevents moisture absorption. The innovative Redi-Dri™ technology ensures that the compound remains free-flowing and non-caking, even in humid environments that typically cause clumping. This enhances ease of handling and measurement, making it ideal for both research and industrial applications.

This combination of high purity and innovative packaging ensures optimal performance and reliability in various applications.

Application

Application statement:

Lithium sulfate, anhydrous, free-flowing, Redi-Dri™ (99.5% trace metals basis) has various applications in research due to its chemical properties and high purity.

Features and Benefits

Lithium sulfate is added to lead-acid batteries to enhance their cycle life and efficiency, making them more effective for use in industries such as automotive and energy storage.

  • In thin-film solar cell fabrication, it is used as a dopant to improve the electrical properties of cadmium sulfide (CdS) cells, thereby boosting their performance.
  • In lithium-ion battery production, lithium sulfate serves as a precursor for synthesizing lithium iron phosphate (LiFePO4) cathodes, valued for their high energy density, long cycle life, and improved safety.
  • It also functions as an electrolyte in the electrochemical characterization of synthesized a-MnO2 for supercapacitor applications.
  • Apart form energy research, it can be used as a catalyst as a catalyst in the elimination reaction that converts n-butyl bromide to 1-butene, achieving nearly 100% yields at temperatures between 320°C and 370°C.
