Zinc ion capacitors(ZICs)have drawn increas-ing 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 charac-terization verifies that B/N dual-doping promotes the physical adsorption/desorption kinetics of anion and the chemical absorption/desorption kinetics of Zn2+,thus improving the electrochemical performance of ZICs.In addition,the quasi-solid-state pouch-type battery exhibited excellent electrochemical durability and mechanical flexi-bility,demonstrating its vast application potential as a flexible power source.Overall,this research not only pre-sents 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.
