Molecular Tailoring of an n/p‐type Phenothiazine Organic Scaffold for Zinc Batteries
Bibliographic record
Abstract
Abstract The p‐type or n‐type redox reactions of organics are being used as the reversible electrodes to build the next‐generation rechargeable batteries with sustainable and tunable characteristics. However, the n‐type organics that store cations generally exhibit low potential (<0.8 V vs. Zn/Zn2+), while the p‐type organics that store anions suffer from limited capacity (<100 mAh g−1). Herein, we demonstrate that bis(phenylamino)phenothiazin‐5‐ium iodide (PTD‐1) containing both n‐type and p‐type redox moieties exhibits a hybrid charge storage mechanism (n/p‐type at low potential, p‐type at high potential). Such a hybrid mechanism combines the advantages of n‐ and p‐type reactions and compensates for the associated drawbacks of each. Accordingly, the aqueous Zn//PTD‐1 full cell shows a high voltage (1.8 Vmaximum or 1.1 Vaverage), a high capacity 188.24 mAh gPTD‐1−1 (achieved at 40 mA g−1), a long‐life and a supercapacitor‐like high power. These results shed new light on the design of advanced organic electrodes.

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.
