Abstract
Abstract Zinc ion capacitors (ZICs) have drawn increasing interest in energy storage devices because of their economic benefits, high safety, and long cycling life. Nevertheless, the lack of high‐performance cathodes for ZICs remains a key challenge. Here, we fabricated B, N co‐doped porous carbon (BN‐C) via a salt template strategy. The aqueous ZICs assembled from BN‐C cathode delivered a high capacity of 190.2 mAh·g −1 and a remarkable energy density of 105.1 Wh·kg −1 . Moreover, systematic characterization verifies that B/N dual‐doping promotes the physical adsorption/desorption kinetics of anion and the chemical absorption/desorption kinetics of Zn 2+ , thus improving the electrochemical performance of ZICs. In addition, the quasi‐solid‐state pouch‐type battery exhibited excellent electrochemical durability and mechanical flexibility, demonstrating its vast application potential as a flexible power source. Overall, this research not only presents a reasonable approach to the large‐scale production of carbon cathode materials with excellent electrochemical performance but also strengthens the essential recognition of the charge storage mechanism of heteroatoms‐doped carbon materials.

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 it
