N2 - Abstract: Composite solid electrolytes based on n-methyl-n-butylpiperidinium tetrafluoroborate [(CH3)(C4H9)C5H10N]BF4–A (where A is γ-Al2O3, SiO2) were synthesized, and their thermal and electrically conductive properties were studied. The conductivity of the (1 – x)[C10H22N]BF4–xAl2O3 composites passes through a maximum at x ~ 0.9, reaching 4.6 × 10–4 S/cm at 130°C for 0.1[C10H22N]BF4–0.9Al2O3. The absence of a thermal effect at the melting temperature of the ionic salt, showing high ionic conductivity, indicates that at x ≥ 0.9 n-methyl-n-butylpiperidinium tetrafluoroborate is in the amorphous state, and ion transport occurs along the ionic salt/oxide interface. In the case of the [C10H22N]BF4–SiO2 composites, the effect of a heterogeneous dopant on the ion transport is less significant, and the conductivity is due to the ionic salt of the additive present in the pores.
