- Abstract
- Composite solid electrolytes based on n-methyl-n-butyl-piperidinium tetrafluoroborate [(CH3)(C4H9)C5H10N]BF4–A (where A is γ-Al2O3, SiO2) were synthesized and their thermal and electrically conductive properties have been studied. It was found that the conductivity of the [C10H22N]BF4–Al2O3 composites passes through a maximum at x~0.9 and reaches a value of 4.6·10-4 S/cm at 130оC for the 0.1[C10H22N]BF4–0.9Al2O3 composite. The absence of a thermal effect at the melting temperature of the ionic salt, which indicates a high ionic conductivity, indicates that at x ≥ 0.9, n-methyl-n-butyl-piperidinium tetrafluoroborate is in the amorphous state and ion transfer occurs along the ionic salt/oxide phase boundary. In the case of [C10H22N]BF4 – SiO2 composites, the effect of a heterogeneous dopant on ion transport is less significant and the conductivity is due to the ionic salt of the additive present in the pores.
