Abstract
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 nanosized diamonds, 0 ≤ x 1, x is the mole fraction). It has been shown by the Powley method that the crystal structure of the low-temperature phase (C4H9)3CH3NBF4 is described by the space symmetry group P42/ncm. It was found that the addition of a nanodiamond inert additive leads to an increase in the electrical conductivity of the composite electrolyte by 4 orders of magnitude up to a value of 1.3∙10–3 S/cm at 145°C at x = 0.98. The theoretical dependences describe well the experimental data in the concentration range 0 ≤ x ≤ 0.99 at temperatures of 84 and 127 оC.
