Abstract Aqueous zinc‐selenium (Zn‐Se) batteries have garnered much attention due to their inherent safety and high specific capacity. Unfortunately, the problem of sluggish redox reaction represents a significant obstacle development aqueous Zn‐Se batteries. Here, nitrogen‐phosphorus asymmetrically coordinated copper single atom catalytic host material (CuN 3 P 1 @C) is synthesized for an battery. The CuN @C exhibits rich porous structure, high‐loading Cu atoms, unique asymmetric coordination environment, which significantly reduces energy barrier between Se Zn, enhancing electrochemical performance Consequently, Se/CuN cathode achieves capacity 756 mAh g −1 at 0.2 A cycling stability 4 000 cycles 5.0 (capacity decay 0.0044% per cycle). Meanwhile, conversion mechanism battery systematically explored via systematical characteristics density functional theory calculations. This work opens up novel approach boosting by modulating atom‐based materials heteroatoms.
