Cost‐Effective Vat Orange 3‐Derived Organic Cathodes for Electrochemical Energy Storage
Bibliographic record
Abstract
Abstract Organic compounds are desirable alternatives for sustainable lithium‐ion battery electrodes. Vat orange 3 ( VO3 , 4,10‐dibromoanthanthrone) is a highly cost‐effective organic dye containing two conjugated carbonyl groups, which can reversibly accept two electrons. The skeleton also contains two bromine atoms, which allows easy incorporation of the anthanthrone unit into polymers through simple reactions. In this work, we report the preparation of organic cathodes derived from the low‐cost VO3 dye for lithium‐organic batteries (LOBs). The results show that polymeric VO3 ‐based materials exhibit remarkably high cyclability and rate performance, because of their effective suppression of dissolution. In particular, the sulfide polymer poly(anthanthrone sulfide) ( PATS ) shows an initial large‐current (0.2 A g −1 ) discharge capacity of 133 mAh g −1 at a potential near 2.4 V. The capacity reaches a maximum capacity of 147 mAh g −1 after 24 cycles and is maintained at 132 mAh g −1 after 300 cycles. Moreover, a full battery cell with the structure: PATS cathode||graphite anode, further delivers an impressive electrochemical performance with an energy density up to 237 Wh kg −1 along with an output voltage of 2.3 V. The present study initiates the use of VO3 ‐based organics, which show promising potential for future application in LOBs on a large scale.

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.
