Abstract

fetched live from OpenAlex

Quinone-based organic molecules show promise as electrode active materials for supercapacitor applications due to their reversible redox activity, high theoretical capacitances, low cost, nontoxicity, and renewability. The use of quinone containing molecules in supercapacitor applications faces challenges due to their low electrical conductivity and their high solubility in aqueous electrolytes that results in low cycling stability. This work addresses these limitations by proposing a novel quinone-composed material, N,N′-bis(2-anthra-quinone)]-perylene-3,4,9,10- tetracarboxydiimide (PDI-DAQ), as an organic molecule electrode for supercapacitors. PDI-DAQ was composited with a low-cost carbon substrate, Ketjenblack carbon black (CB), and demonstrated a specific capacitance of up to 318.6 F g −1 at 5 mV s −1 in 1 M H 2 SO 4 electrolyte at an optimized mass ratio of 1:1 (PDI-DAQ to CB). This material had a capacity retention of 61.2 % after 10,000 cycles at 100 mV s −1 . Ultimately, PDI-DAQ as a supercapacitor material demonstrates the performance advantages of covalently bonding redox-active quinone molecules and preparing a PDI-DAQ/CB OME through a simple preparation process.

Teacher imitation

Not 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.
