Data for: SODIUM ION CONDUCTING GEL POLYMER ELECTROLYTE USING POLY(VINYLIDENE FLUORIDE HEXAFLUOROPROPYLENE)
Description of this data
Gel polymer electrolyte (GPE) films using polyvinylidene fluoride – hexafluoropropylene (PVdF – HFP) matrix were prepared for aim to achieve good sodium-ion conductivity at room temperature. GPE of PVF-HFP were formed by microporous PVDF-HFP membranes filled and swollen in different liquid electrolytes: GPEs were formed by microporous PVDF-HFP membranes filled and swollen in different liquid electrolytes: NaClO4, NaPF6 and NaTFSI salts dissolved in mixtures of carbonate solvents (propylene carbonate (PC), fluoroethylenecarbonate (FEC)) or ionic liquids (1-ethyl-3-methylimidazolium bis(trifluoromethane-sulfonyl)imide and 1-butyl-3-methyl bis(trifluoromethanesulfonyl)imide). The effect of different electrolytes on the structure and morphology, electrolyte absorption and sodium ionic conductivity of activated membrane were investigated. GPEs showed “sponge-like” structure with high porosity of 80 – 85 % and large pore size. The ionic conductivity of GPEs reached 1-2 mS.cm-1 at room temperature. Sodium intercalation into Na0.44MnO2 electrode was performed in coin-cell type by using GPEs as conduction media. Cycling data of sodium cell using PVdF-HFP/NaClO4 1M-PC:2%FEC exhibited an excellent stable specific capacity of 100 mAh.g-1 at room temperature.
