Knowra Lithium iron phosphate battery Lithium iron phosphate battery A rechargeable lithium-ion battery that uses lithium iron phosphate (LiFePO₄) as its cathode material. It is known for thermal stability, long cycle life, and lower energy density than many layered-oxide lithium-ion batteries.
Lithium iron phosphate : A lithium-containing iron phosphate compound with the formula LiFePO₄, used as a lithium-ion battery cathode material. This olivine-structured compound stores and releases lithium ions during charging and discharging.
Lithium nickel manganese cobalt oxide : A layered lithium-ion cathode material containing nickel, manganese, and cobalt, commonly abbreviated NMC. NMC cells generally offer higher energy density but rely on cobalt-containing layered cathodes.
Electric vehicle : A vehicle propelled partly or entirely by one or more electric motors. LFP packs are widely used where durability, cost, and safety matter more than maximum range per unit mass.
Cobalt : A chemical element used in many lithium-ion cathodes to stabilize layered crystal structures. LFP cathodes avoid cobalt, reducing exposure to its supply-chain and sourcing concerns.
John B. Goodenough : An American physicist whose research advanced lithium-ion battery cathode materials. His research group reported lithium iron phosphate as a rechargeable battery cathode in 1997.
Olivine crystal structure : A crystal structure found in minerals and compounds, including lithium iron phosphate. Its strong phosphate framework helps stabilize the cathode during repeated lithium-ion movement.
Lithium nickel cobalt aluminum oxide : A layered lithium-ion cathode material containing nickel, cobalt, and aluminum, commonly abbreviated NCA. NCA provides a high-energy-density alternative, with different cost and thermal-stability trade-offs.
Grid energy storage : The storage of electrical energy for later use in power grids. Long cycle life and thermal stability suit LFP batteries to frequent stationary charging and discharging.
Lithium iron phosphate battery recycling : The recovery or reuse of materials from spent lithium iron phosphate batteries. The absence of valuable cobalt and nickel can make material recovery less economically attractive.
Arumugam Manthiram : An Indian-American materials scientist known for research on battery materials and electrochemistry. His work with Goodenough’s group helped establish polyanion compounds as lithium-battery cathodes.
