Olivine phosphate electrode material

Lithium ferrous(II) phosphate (LiFeP04) is a positive electrode material for lithium-ion batteries, which, so far, has been mainly used in power lithium-ion batteries [1]. It is commonly called lithium iron(II) phosphate and is also used in fertilizers. In 1996, the Japanese NTT Corporation disclosed for the first time an olivine structured compound, A MP04 (A is an alkali metal and M a combination of Co and Fe) as a positive electrode material for lithium-ion batteries. In 1997, Prof. John B. Goodenough and his group at the University of Texas at Austin, United States, reported the characteristics of reversible lithium intercalation/deintercalation into/from LiFeP04. However, at the initial stage, this positive electrode material did not raise much attention since its electronic and ionic conductivities are very low and...
