Abstract Developing electrode materials with high tap density, low cost, and superior performance poses a formidable challenge in electrochemistry. The impressive exhibited by most electrodes comes at the expense of density severely limiting their practical applications. Here, combining computational experimental results, an approach for rich heterostructure (Cu 2 S/Na S n ) from cheap copper smelting slag enabled electrochemical process is proposed, reducing diffusion energy barrier 0.82 to 0.28 eV Na + , as well delivering impressively 3.32 g cm −3 . Furthermore, activation that irreversibly generates more stable Cu after first charge progress parent also revealed in/ex situ analytical techniques. As expected, assembled sodium ion capacitors (SICs) achieve (74.4 Wh kg −1 power (20 000 W outstanding capacity retention 81.5% 10 cycles, over 76% its 13.4 s, which surpasses achieved state‐of‐the‐art SICs.

Abstract Interfacial coupling strategy has allured extensive attention for the possibility to endow active electrode materials with superior performance. However, design of strong engineering interfacial evolution during electrochemical processes is very challenging. Herein, inspired by powerful robotic arms and density functional theory calculations, multiple groups identified intense affinity V atom are successfully grafted on carbon nanotubes (CNTs), thereby in situ building robust bonds (VOC VC) tightly anchor VS 4 particles. The largely decreased band gaps energy barriers show fortified conductivity ‐CNT heterostructure. Besides, spacial confinement effect induced linkages substantively enhances mechanical properties inhibit structural collapse, restrains dissolution polysulfides as verified molecular dynamics simulations, thus prolonging life span. Excellent 105.5 Wh kg –1 can be delivered after assembling full sodium‐ion capacitors (activated carbon//VS ‐CNT).
