Lithium Iron Phosphate (LFP)

Lithium Iron Phosphate (LiFePO4) Sputtering Target is a material used in thin-film deposition processes, specifically sputtering, to create thin layers of lithium iron phosphate on various substrates. Sputtering is a common method for depositing materials onto surfaces for use in electronics, energy devices, and other applications. LiFePO₄ sputtering targets are typically used for the deposition of thin films in applications like solid-state batteries, sensors, and thin-film transistors, or for creating coatings that require the specific properties of lithium iron phosphate.

Chemical Composition:

Chemical formula：FeLiO4P

Molar mass： 157.757

Purity: High-purity LiFePO₄ targets (typically 99% or higher) are essential for achieving consistent film quality and performance in sputtering applications.

Physical Properties:

Appearance: The LiFePO4 sputtering target is typically a dense, solid disk, often dark gray or black in color, resembling the powder form but in a solidified and shaped state for sputtering.

Density: Around 3.6 g/cm³, similar to the bulk material. This density helps ensure that the sputtering target provides a stable and consistent source of material during deposition.

Size and Shape: Sputtering targets are usually manufactured in disk shapes with a diameter ranging from 2 inches to 4 inches, although custom sizes can be produced depending on the application. The thickness of the target can also vary depending on the intended sputtering process.

Applications:

Solid-State Batteries: One of the most common applications for LiFePO4 sputtering targets is the fabrication of solid-state lithium-ion batteries, where thin layers of LiFePO4 are used as cathodes. These batteries are gaining popularity due to their safety, high stability, and long cycle life.

Thin-Film Energy Storage Devices: LiFePO₄ thin films are used in energy storage devices where compact and lightweight batteries or capacitors are required, such as in microelectronics and portable energy storage systems.

Thin-Film Coatings: LiFePO4 sputtering targets can also be used to create protective or functional coatings for electronic components, semiconductor devices, or sensors that require the specific electrochemical properties of lithium iron phosphate.

Electrochemical Sensors: LiFePO4 thin films can be used as electrodes in electrochemical sensors, particularly those designed for the detection of ions or gases in various applications.
