The ionic conductivity, crystal structure and multi-fractal parameters of sections of grain boundaries in CuCr1−xVxS2 superionic conductors, with 0 ≤ x ≤ 0.3, were investigated. It was found that an increase in the surface area of the grain boundaries and the complication of their shape in such compounds facilitated ion transport. The effect of crystal-structural peculiarities upon the grain structure of these compounds was revealed.
