|Section2= |Section7= }} Lithium iron phosphate (), also known as LFP, is a compound used in lithium iron phosphate batteries〔“Phospho-olivines as Positive-Electrode Materials for Rechargeable Lithium Batteries” A. K. Padhi, K. S. Nanjundaswamy, and J. B. Goodenough, J. Electrochem. Soc., Volume 144, Issue 4, pp. 1188-1194 (April 1997)〕 (related to Li-Ion batteries). It is targeted for use in power tools, electric vehicles and solar energy installations. It is also used in OLPC XO education laptops. Most lithium batteries (Li-ion) used in 3C (computer, communication, consumer electronics) products use cathodes of other lithium molecules, such as lithium cobalt oxide (LiCoO2) lithium manganese oxide (LiMn2O4) and lithium nickel oxide (LiNiO2). The anodes are generally made of carbon. The annual production of lithium carbonate available to the automotive industry is estimated at only 30,000 tonnes in 2015.〔(Pag4.- The trouble with lithium )〕 While a natural lithium iron phosphate mineral exists (triphylite) issues with purity and structure make it unsuitable for use in batteries. ==LiMPO4== is a member of the olivine group, which has a general chemical formula of LiMPO4, where M refers to any metal, including Fe, Co, Mn and Ti. The first commercial LiMPO4 was C/ and therefore, people refer to the whole group of LiMPO4 as lithium iron phosphate, . However, more than one olivine compound may be used as a battery's cathode material. Olivine compounds such as AyMPO4, Li1-xMFePO4, and -zM have the same crystal structures as LiMPO4 and may replace in a cathode. All may be referred to as “LFP”. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lithium iron phosphate」の詳細全文を読む スポンサード リンク
