Synthesis and Study of the Physicochemical Properties of Composite Solid Electrolytes (C4H9)3CH3NBF4–Cnanodiamonds
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.
