Abstract
Novel process for the preparation of finely divided, nano-structured, olivine lithium metal phosphates (LiMPO) (where metal M is iron, cobalt, manganese, nickel, vanadium, copper, titanium and mix of them) materials have been developed. This so called Polyol' method consists of heating of suited precursor materials in a multivalent, high-boiling point multivalent alcohol like glycols with the general formula HO—(—CHO—), —H where n=1-10 or HO—(—CHO—)—H where n=1-10, or other polyols with the general formula HOCH—(—CHOH—)—H where n=1-10, like for example the tridecane-1,4,7,10,13-pentaol. A novel method for implementing the resulting materials as cathode materials for Li.-ion batteries is also developed.
