LiFePO4 Introduction
Lithium iron phosphate (molecular formula is LiFePO4, also known as LFP), is used as cathode material for lithium-ion batteries (also called lithium iron phosphate battery). Its characteristic does not include noble elements such as cobalt, the price of raw material is lower and both phosphorus and iron are abundant on Earth which lowers raw material availability issues. The annual production of lithium carbonate available to the automotive industry is estimated at only 30,000 tonnes in 2015. While a natural lithium iron phosphate mineral exists (triphylite) issues with purity and the structure of the material make it unsuitable for use in batteries.

Famous quotes containing the word introduction:
“We used chamber-pots a good deal.... My mother ... loved to repeat: “When did the queen reign over China?” This whimsical and harmless scatological pun was my first introduction to the wonderful world of verbal transformations, and also a first perception that a joke need not be funny to give pleasure.”
—Angela Carter (1940–1992)
