Template‐Induced Graphitic Nanodomains in Nitrogen‐Doped Carbons Enable High‐Performance Sodium‐Ion Capacitors
Bibliographic record
Abstract
Sodium‐ion capacitors (SICs) have great potential in energy storage due to their low cost, the abundance of Na, and the potential to deliver high energy and power simultaneously. This article demonstrates a template‐assisted method to induce graphitic nanodomains and micro‐mesopores into nitrogen‐doped carbons. This study elucidates that these graphitic nanodomains are beneficial for Na + storage. The obtained N‐doped carbon (As8Mg) electrode achieved a reversible capacity of 254 mA h g −1 at 0.1 A g −1 . Moreover, the As8Mg‐based SIC device achieves high combinations of power/energy densities (53 W kg −1 at 224 Wh kg −1 and 10 410 W kg −1 at 51 Wh kg −1 ) with outstanding cycle stability (99.7% retention over 600 cycles at 0.2 A g −1 ). Our findings provide insights into optimizing carbon's microstructure to boost sodium storage in the pseudocapacitive mode.

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; both teacher heads agree on what is shown here.
