| 摘要 |
The invention relates to a method for producing a compound of formula LiMPO4, in which M represents at least one metal of the first transition series, said method comprising the following steps: a) production of a precursor mixture containing at least one Li+ source, at least one M2+ source and at least one PO43- source in order to obtain a precipitate and produce a precursor suspension; b) treatment of the precursor mixture and/or precursor suspension by dispersion or grinding, until the D90 value of the particles in the precursor suspension is less than 50 mu m; and c) extraction of LiMPO4 from the precursor suspension obtained in step b), preferably by conversion under hydrothermal conditions. The resultant material exhibits particularly advantageous particle-size distributions and electrochemical characteristics when used in electrodes. |
