Lithium Iron Phosphate - Theory

Theory

This lithium battery’s cathode material of olivine composition is already being mass produced by several up source professional material manufacturers. It is expected to widely expand the applications in the field of lithium batteries, and take it to the new fields such as electric bicycles, gas-electric hybrid vehicles and automation vehicles; In Tokyo Japan, a research group led by Professor Atsuo Yamada of Tokyo University of Technology, published a report on August 11, 2008 issue of “natual materials” which included the following statement: the lithium-ion iron phosphate battery will be used as the power source for environmental-friendly electric cars, which have great future prospects. The Tokyo University of Technology and North East University research group is led by Professor Atsuo Yamada. The group uses neutron irradiation phosphate iron, and then analyzes the interaction between neutron and materials to study the motion status of lithium-ion in iron phosphate. The researchers concluded that in the lithium iron phosphate, lithium-ion extended in accordance with a certain straight direction, has a different motion pattern with the existing lithium-ion electrode materials such as cobalt. This is a coincidence with the original assume theory, the analysis results with the use of neutron diffraction, confirms that lithium iron phosphate (molecular formula is LiFePO₄, also known as LFP) is able to ensure the security of large input/output current of lithium battery.
