Influence of Sample History on the Morphology and Transport Properties of PEO−Lithium Salt Complexes
Bibliographic record
Abstract
We provide clear evidence of the effect of the solvent used for sample preparation on the morphology and transport properties of PEO−lithium salt (LiTFSI, LiBF 4, or LiClO 4 ) complexes. The surface structure, thermal behavior, and conductivity of the films along with the measured diffusion coefficients and transport numbers of the ionic species are clearly different whether acetonitrile (good solvent of PEO) or methyl formate (poor solvent) was used. Interestingly, the samples with the lowest conductivity have the highest diffusion coefficients, indicative of a difference in carriers concentration. We infer that the polymer chains keep memory of the solvent, and their generated spatial organization is directly implied in conductivity through the use of specific pathways for ionic mobility. Since the variations observed here are of the same amplitude or greater than those observed for some deliberate modification of the polymer electrolytes (i.e., nanoparticles addition, mechanical strain, etc.), great care must now be exercised in giving precise sample history.

How this classification was reachedexpand
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.
