Description

General description

Lithium iron(II) phosphate (LiFePO4), also called LFP, is a crystalline, grey-to-black powder with an olivine crystal structure. This unique structure facilitates efficient diffusion of lithium-ions, thanks to the three-dimensional interconnected iron phosphate tetrahedra that form pathways for lithium ions to diffuse. Additionally, the structure is highly stable, not deforming, even after thousands of cycles of lithium intercalation. Our LiFePO4 powder is manufactured to meet high purity with a tightly controlled particle size of less than 5 μm.

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Click here for more details.

Application

LiFePO₄ is a widely used cathode for rechargeable Li batteries. It has high energy density, wide operating temperature, thermal stability, long cycle life and application life, environmental friendliness, and safety that make it a promising electrode material for greener and safer lithium-ion batteries.

Features and Benefits

LiFePO4-based batteries can last longer, operate safely and reliably, and power devices in a wide range of temperatures.
✔ Achieves 1000s of cycles
✔ Safer than cobalt or manganese-based cathode materials
✔ Reliable performance
