Design and Synthesis of a Facile Solution‐Processing and Ultrastable Crosslinkable Branched Nitroxide Polymer
Bibliographic record
Abstract
Abstract A general critical challenge for nitroxide polymers being used as cathode materials is keeping the good solubility during the processing and good solvent resistance during charging and discharging. To address this issue, herein, a new photo‐crosslinkable branched nitroxide polymer is designed and synthesized via reversible addition‐fragmentation chain transfer copolymerization of 2,2,6,6‐tetramethyl‐4‐piperidyl methacrylate, cinnamoyl ethyl methacrylate, and ethylene glycol dimethacrylate, followed by oxidation using 3‐chloroperoxybenzoic acid. The as‐synthesized polymer can dissolve in ethyl alcohol with environmental‐friendly processing, and then can easily change into crosslinked polymer with highly resistance to organic electrolyte after UV irradiation. The crosslinked nitroxide polymer‐based cathode achieves remarkable cycle stability with a capacity retention of 90% over 1000 charge–discharge cycles at 10 C current rate, superior to that of the un‐crosslinked one with capacity retention of 65% over 1000 cycles.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
