“…The IR spectra of the obtained electrolytes are identical to the spectra presented in the Supplementary of the paper [26]. The presence of organic solvents in membranes is revealed by a set of vibrational frequencies inherent in these solvent molecules.…”

“…It was found by separate experiments that the membrane intercalated by the four-component mixture of EC-PC-THF-DMA has an almost an order of magnitude higher electrical conductivity (more than 4 mS cm -1 at 30 °C) compared to the membrane intercalated by EC-PC (ca. 0.7 mS cm -1 at 30 °C) [26], with close electrochemical stability (Table 1). Nafion 117 membrane intercalated by EC-PC ( Fig.…”

“…Initially electrolytes based on the Nafion membrane were proposed for lithium-ion batteries [17][18][19][20][21][22][23][24], and later for their sodium-ionic analogs [8,25,26]. Such electrolytes are obtained by transferring Nafion from hydrogen to sodium form (ion exchange in aqueous solutions of sodium salts), followed by removal of water and impregnation with an aprotic solvent.…”

The possibilities of manufacturing batteries with Nafion 117 membranes in the Na+-form intercalated by mixtures of non-aqueous organic solvents used both as electrolyte, separator and binder were investigated. Electrochemical stability of various organic solvent mixtures based on N,N-dimethylacetamide, ethylene carbonate, propylene carbonate, tetrahydrofuran was characterized. It was shown that sodium battery based on Nafion-Na membrane intercalated by mixture of ethylene carbonate ‑ propylene carbonate with Na3V1.9Fe0.1(PO4)3/C positive electrode is characterized by a discharge capacity of ca. 110 mAh g-1 (C/10) at room temperature and shows the ability to cycle for a long time. Batteries with Nafion membrane electrolytes, containing N,N-dimethylacetamide were characterized by capacity fading during cycling, which is due to the interaction of N,N-dimethylacetamide and a negative sodium electrode.

The possibilities of manufacturing batteries with Nafion 117 membranes in the Na+-form intercalated by mixtures of non-aqueous organic solvents used both as an electrolyte, separator, and binder were investigated. Electrochemical stability of various organic solvent mixtures based on N,N-dimethylacetamide, ethylene carbonate, propylene carbonate, and tetrahydrofuran were characterized. It was shown that a sodium battery based on a Nafion-Na membrane intercalated by mixture of ethylene carbonate and propylene carbonate with a Na3V1.9Fe0.1(PO4)3/C positive electrode is characterized by a discharge capacity of ≈110 mAh·g−1 (current density of 10 mA·g−1) at room temperature and shows the ability to cycle without degradation during 20 cycles. Batteries with Nafion membrane electrolytes, containing N,N-dimethylacetamide, were characterized using capacity fading during cycling, which is due to the interaction of N,N-dimethylacetamide and a negative sodium electrode.
