General description

Lithium hexafluorophosphate (LiPF₆), battery grade, ≥99.99% trace metals basis comes as a white powder with trace metal impurities < 100.0 ppm. Lithium hexafluorophosphate is a class of electrolytic materials that can be used in the fabrication of lithium-ion batteries. Lithium-ion batteries consist of anode, cathode, and electrolyte with a charge-discharge cycle. These materials enable the formation of greener and sustainable batteries for electrical energy storage.

Application

Lithium hexafluorophosphate (LiPF₆) battery grade is designed for battery research. It can be used in the research and development of lithium-ion batteries (LIBs). Its role as a primary electrolyte salt is pivotal due to its high ionic conductivity, electrochemical stability, and compatibility with a wide range of electrode materials. It helps in the formation of a stable solid electrolyte interphase (SEI) on the anode surface, which is essential for the longevity and stability of the battery, reducing the risk of thermal runaway and enhancing the overall safety of lithium-ion batteries. LiPF₆ can be used in the development of ionic liquid electrolytes, which offer advantages such as non-flammability and wider electrochemical windows.

Features and Benefits

The product is designed with stringent parameters to fulfill the research needs in batteries. It ensures minimal interference from contaminants in trace metal analysis, providing high-purity results.
  • Exceptional Purity: ≥99.99% purity minimizes contamination from trace metals, ensuring suitability for applications sensitive to even minute impurities.
  • Consistent Performance: Ultra-high purity guarantees consistent performance across various applications, reducing variability and enhancing reliability.
  • High Purity Standard: Ideal as a standard or reagent for trace metal analysis and high-precision analytical techniques, ensuring accurate and reliable results.
  • Battery grade for use in battery applications, ensuring suitability and performance.
