Aqueous rechargeable zinc-ion batteries promise attractive advantages including safety, high energy density, and low cost. However, the uncontrollable dendrite growth and intricate side-reactions impede the practical application. Herein, we report a bifunctional nitrogen doped carbon network as interlayer (NCL) in cells to suppress the dendrite growth. In physical effect, NCL can balance the interfacial electrostatic field of Zn surface and guide Zn ions to deposit uniformly. In chemical effect, the nitrogen doped carbon active sites can recons...
