Achieving a dendrite-free Zn anode at high current densities via in situ polymeric interface design

The Zn 5 (OH) 8 Cl 2 ·H 2 O-doped PAM skeleton is distributed closely and orderly on the surface of the pristine Zn foil, which provides a site for electroplating Zn 2+ . A part of plated Zn present in the form of “lying flat” on this skeleton. While Zn dendrites grow arbitrarily without additive.
