General description

Lithium iron(III) oxide is a class of electrode material that can be used in the fabrication of lithium-ion batteries. Lithium-ion batteries consist of anode, cathode, and electrolyte with a charge-discharge cycle. These materials enable the formation of greener and sustainable batteries for electrical energy storage.
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. Find details here.

Application

LiFeO2 can be used as a non-toxic cathode material with a specific capacity of ~120 mAhg−1 at a rate of 100 mAg−1. It can further be used in the fabrication of lithium-ion batteries and rechargeable batteries.
Studied for its use as a long-lived porous cathode in molten carbonate fuel cells.
