Solid Polymer Single-Ion Conductors: Synthesis and Properties
Bibliographic record
Abstract
Optimal battery electrolyte materials provide for high transport of a single ionic species. Here we report solid single-ion conductors (SICs) based on composite polymer electrolytes consisting of poly(ethylene glycol) (PEG) and an organic−inorganic component (OIC) formed in situ . The resulting solid films showed transport properties with conductivity as high as 10 - 4 S/cm at room temperature and a cation transference number of 0.9. The materials were characterized using solid-state NMR, differential scanning calorimetry, X-ray diffraction, transmission electron microscopy (TEM), and impedance spectroscopy. The OIC was formed by sol−gel reaction of the three precursors: the sodium salt of 3-trihydroxysilylpropylmethylphosphonate (SPMP), (3-glycidylopropyl)trimethoxysilane (GLYMO), and tetramethoxysilane, resulting in a high degree of three-dimensional network character of OIC within SIC solid polymer electrolytes as indicated by solid-state NMR. TEM examination of calcined OIC shows that the silicate particles are fairly uniform and measure approximately 15 nm in diameter. Their uniformity and small size lead to the homogeneity of the composite material. The glycidyl group of GLYMO enhances the compatibility of OIC with PEG. The phosphonate group of SPMP furnishes immobile anions, while Na + cations are the only source of conductivity.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
