Pectin Extracted by a Recyclable Molecular Mixture: A Promising Material for Porous Membranes in Quasi-Solid-State Na-Ion Batteries.

ABSTRACT: In this work, we explored a solvent-based extraction of pectin from apple pomace and evaluated the extracted pectin as a precursor for porous quasi-solid-state Na-ion battery membranes, alongside testing hard carbon derived from commercial pectin as an electrode material. A screening of 10 distinct ionic liquids (ILs) and 6 different antisolvents revealed that N,N-dimethylbutylammonium acetate ([DMBA]-[OAc]), combined with ethanol, was highly effective in pectin extraction, while the same IL with 1-butanol as antisolvent yielded a purer form of the pectin product. Additionally, [DMBA]-[OAc] did not behave as an IL and resembled a molecular mixture based on ¹H NMR and conductivity measurements. A two-level fractional design was employed with four factors, considerin
