A dispersion may include 1 to 50% by weight of lithium metal phosphate of a general formulaLiMN(PO),wherein M is Ti, Zr or Hf; N is a metal other than Li and M; 0≤a≤0.6, 0≤b≤0.6, 0≤c≤0.6, 0≤d≤0.8; and 50 to 99% by weight of trialkyl phosphate. A coating composition may include such a dispersion and such dispersions can be used in lithium ion batteries.

The present invention relates to a process for the continuous preparation of core-shell nanoparticles, comprising a core of a core material, preferably of a semiconductor material, and a shell of a shell material, preferably of a semiconductor material, wherein selected starting materials for the shell material are mixed with a dispersion of nanoparticles of the core material and are passed continuously through a reaction zone of a tubular reactor, and other starting materials for the shell material are fed to the reaction zone of the tubular reactor at two or more locations, preferably via a tubular membrane, and the starting materials for the shell material react in the reaction zone to form a shell around the nanoparticles of the core material. The invention also relates to the tubular reactor with the membrane and its use for the continuous synthesis of core-shell nanoparticles. The invention also relates to core-shell nanoparticles comprising a core of a core material, preferably of a first semiconductor material, and an outer shell of a shell material, characterized in that, between core and shell, there is only a layer of a transition zone, in which the proportion of the core material gradually decreases toward the shell, while the proportion of the shell material gradually increases.
