A 3D Network Based on Poly(ε-caprolactone) Macromonomers as Polymer Electrolyte for Solid State Lithium Metal Batteries
Bibliographic record
Abstract
A commercial low molecular weight poly( ε -caprolactone) was chain-extended with acrylate moieties to create a macromonomer, which was then polymerized by radical reaction in the presence of different amounts of lithium bis(trifluoromethanesulfonyl)imide, LiTFSI, to obtain a 3D network Solid Polymer Electrolyte (SPE). The SPE with the largest ionic conductivity (24 μ S cm −1 at 50 °C) had a high transference number of 0.78 and could form a self-standing film. Lithium Iron Phosphate (LFP)/SPE/Li cells made with this SPE attained a specific capacity of 120 mA.h.g −1 . At 50 °C, the initial capacity declined by less than 15% after 150 cycles at 0.2 C. No evidence of degradation and dendrite growth was observed, indicating that the 3D network was stable. Thus, caprolactone-based 3D networks are promising materials for the fabrication of all solid-state batteries with high stability and cyclability, at near room temperature.

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.
