Description
Graphite Fluoride (Carbon Monofluoride) Micron Powder for Li-ion Battery, 10–20 µm, F/C Ratio: 0.8–1.0
Graphite Fluoride, also referred to as Carbon Monofluoride (CFₓ), is a unique fluorinated carbon compound renowned for its excellent electrochemical properties, thermal stability, and high energy density. Produced via high-temperature fluorination of graphite, this material features a fluorine-to-carbon (F/C) ratio between 0.8 and 1.0, enabling optimal performance as a cathode material in lithium-based primary batteries, especially those of the BR-type.
With a controlled particle size distribution of 10–20 microns and a specific surface area of 302 m²/g, this powder is engineered for maximum interfacial contact and efficient ion exchange in lithium-ion battery cells. Beyond battery applications, Graphite Fluoride is also employed in imaging technologies, incandescent lighting, and as a solid lubricant in high-vacuum or high-temperature environments.
