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

Professor Qiao’s laboratory lays out recent advances in conversion type lithium metal fluoride batteries. This review explores key concepts in developing electrochemically stable microstructures for wide Li-ion insertion channels.

Solid oxide fuel cells (SOFC) and solid oxide electrolyzers (SOE) are in the early stages of development; however, the performance that has been achieved shows promise for conversion between chemical and electrical energy.

Li-ion batteries are currently the focus of numerous research efforts with applications designed to reduce carbon-based emissions and improve energy storage capabilities.

Lithium-ion batteries (LIBs) have been widely adopted as the most promising portable energy source in electronic devices because of their high working voltage, high energy density, and good cyclic performance.
