An aqueous rechargeable zinc‐ion battery on basis of an organic pigment
Bibliographic record
Abstract
Neutral aqueous rechargeable zinc‐ion batteries are receiving continuous attention because of their advantages of low cost, high safety, environmental friendliness, and high performance, which are difficult to attain with current organic electrolyte‐based batteries. In this work, a high‐performance aqueous Zn‐ion battery based on the organic pigment 3,4,9,10‐perylene‐tetracarboxylic acid dianhydride (PTCDA) is developed. An electrochemical test shows that the PTCDA possesses a high specific discharge capacity of 136 mAh·g −1 at a current density of 10 mA·g −1 . Moreover, the PTCDA cathode displays a good rate performance (77 mAh·g −1 at 1 A·g −1 ) and an excellent cycle life with a capacity retention of 80% after 2000 cycles. Furthermore, electrochemical analysis and structural characterization originally reveal that the PTCDA cathode undergoes a sequential Zn 2+ and H 3 O + insertion and extraction process, which is reversible and cycling stable.

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.
