N2 - The paper presents the results of studies of the structural, thermal, and transport properties of solid composite electrolytes (1 – x)(C4H9)3CH3NBF4–xCND (where CND are nanodispersed diamonds, 0 ≤ x < 1, x is the mole fraction). It was shown by the Pawley method that the crystal structure of the low-temperature (C4H9)3CH3NBF4 phase is described by the space symmetry group P42/ncm. The addition of an inert nanodiamond additive led to an increase in the electric conductivity of the composite electrolyte by four orders of magnitude to 1.3 × 10–3 S/cm at 145°C and at x = 0.98. The theoretical dependences adequately describe the experimental data in the concentration range 0 ≤ x ≤ 0.99 at temperatures of 84 and 127°C.
