Аннотация

In this work, sodium-ionic polymer electrolytes based on polyvinyl alcohol (PVA) and sodium rhodanide (NaSCN) have been investigated as promising materials for energy storage devices. The main attention is paid to the study of the influence of NaSCN concentration on the ionic conductivity, phase transitions and structural changes of the system in the temperature range 293–373 K. The results of differential thermal analysis, spectroscopy and electrochemical impedance measurements are presented, which showed a significant increase in specific ionic conductivity at a concentration of 20 wt % NaSCN. NaSCN. An improvement in ionic transport is observed due to the breaking of hydrogen bonds in the polymer matrix and an increase in the amorphous phase of the polymer. Quantum chemical calculations demonstrated the influence of solvation and hydration on the properties of ions in the system, indicating a favourable interaction of sodium cations with OH-groups of PVA.
