Abstract: A dispersion may include 1 to 50% by weight of lithium metal phosphate of a general formula Li1+aM2−bNc(PO4)3+d, 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.
