Lithium iron phosphate (LFP) is an inorganic compound with the formula LiFePO4. It is a gray, red-grey, brown or black solid that is insoluble in water. This powder form allows for easier integration into the production of battery cells, where it is typically combined with other materials to form electrodes.
Chemical formula：FeLiPO4
Molar mass： 157.757g/mol
Purity: High-purity LiFePO₄ powder (typically 99% or higher) is required for high-performance applications in batteries and energy storage systems.
LFP powder is coated by carbon for use in lithium ion batteries as the cathode material. Carbon-coated lithium iron phosphate (C-LiFePO4) powders have been produced at the commercial scale by a controlled solid-state reaction method.
Appearance: Lithium iron phosphate powder typically appears as a fine, grayish or black powder. The color can vary slightly depending on the production process and any additives used.
Particle Size: The powder generally consists of fine particles, often ranging from nanometers to micrometers in size. The specific particle size distribution can be adjusted to improve performance in specific applications, such as battery energy density or rate of charge/discharge.
Density: Approximately 3.6 g/cm³.
Crystallinity: The powder is often crystalline, and the crystallinity affects its electrochemical properties and overall performance in battery applications.
Thermal Stability: Lithium iron phosphate powder has a high thermal stability, allowing it to withstand higher temperatures without degradation, which is essential for maintaining battery safety.
Lithium-Ion Batteries: The most significant use of LiFePO₄ powder is in the production of cathodes for lithium-ion batteries. These batteries are used in various applications, such as:
Supercapacitors: LiFePO₄ can be used in combination with supercapacitors to enhance the energy storage capacity of hybrid energy storage devices.
Sputtering Targets: LiFePO₄ powder is sometimes used to produce sputtering targets for thin-film deposition in electronics manufacturing.
Other Advanced Battery Technologies: Lithium iron phosphate is also being explored for use in other types of advanced energy storage technologies, such as solid-state batteries and hybrid systems.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo.
