Title:
Composition of lithium metal-phosphate under Hot water conditions
Document Type and Number:
Japanese Patent JP5957225
Kind Code:
B2
Abstract:
The present invention relates to a process for the preparation of compounds of general formula (I) Lia-bM1bQ1-cM2cPd-eM3eOx (l), wherein Q has the oxidation state +2 and M1, M2, M3,a, b, c, d, e and x are: Q: Fe, Mn, Co, Ni, M1: Na, K, Rb and/or Cs, M2: Mg, Al, Ca, Ti, Co, Ni, Cr, V, Fe, Mn, wherein Q and M2 are different from each other,M3: Si, S, F a: 0.8-1.9, b: 0-0.3, c: 0-0.9, d: 0.8-1.9, e: 0-0.5, x: 1.0-8, depending on the amount and oxidation state of Li, M1, M2, P, M3, wherein compounds of general formula (I) are neutrally charged, comprising the following steps (A) providing a mixture comprising at least one lithium-comprising compound, at least one Q-comprising compound, in which Q has at least partially an oxidation state higher than +2, and at least one M1-comprising compound, if present, and/or at least one M2-comprising compound, if present, and/or least one M3-comprising compound, if present, and at least one reducing agent which is oxidized to at least one compound comprising at least one phosphorous atom in oxidation state +5, and (B) heating the mixture obtained in step (A) at a temperature of 100 to 500° C. and at an autogeneous pressure to reduce Q to oxidation state +2 and to obtain a compound of general formula (I).
