<p>#CMT# #/CMT# Production of a compound of formula LiMPO 4 (where M is a metal of the first transition series) comprises producing a precursor mixture containing at least one Li +> source, at least one M +> source and at least one PO 4 3-> source to obtain a precipitate and produce a precursor suspension, treating the precursor mixture and/or precursor suspension by dispersing or grinding until the D90 value of the particles in the precursor suspension is less than 50 mu m, and extracting the LiMPO 4 from the suspension, preferably under hydrothermal conditions. #CMT#USE : #/CMT# Used in secondary batteries. #CMT#ADVANTAGE : #/CMT# The compound has good electrochemical properties. #CMT#INORGANIC CHEMISTRY : #/CMT# Preferred Features: The D90 value of the particles in the precursor suspension is maximum 20 mu m, preferably maximum 15 mu m. M is Fe, or Fe, Mn, Co and/or Ni. The LiMPO 4 is obtained in a phase-pure form. Dispersing and grinding treatment is carried out before or during precipitation of the precursor mixture and continued until the conclusion of the precipitation. #CMT#ORGANIC CHEMISTRY : #/CMT# Preferred Features: The D90 value of the particles in the precursor suspension is maximum 20 mu m, preferably maximum 15 mu m.
