Preparation of lithium compound, useful as active electrode material for lithium batteries, comprises reacting a first precursor solid of metal complex with a lithium based second precursor at specific temperature

摘要

Preparation of lithium compound or its derivatives comprises reacting a first precursor solid of metal complex with a lithium based second precursor at = 600[deg] C. Preparation of lithium compound of formula LiMPO 4 or its derivatives comprises reacting a first precursor solid of metal complex of formula XMPO 4.nH 2O (where n is the number of water molecules associated with XMPO 4 entity) with a lithium based second precursor at = 600[deg] C. M : a transition metal consisting of Co, Ni, Mn or Fe; and X : -NH 4 radical or H. An independent claim is included for the lithium compound or its derivatives comprising a specific Brauner-Emmet-Teller (BET) surface of greater than or equal to 5 m 2/g and few agglomerate particles formed by wafer.
