Abstract Zinc powder (Zn‐P) anodes have significant advantages in terms of universality and machinability compared with Zn foil anodes. However, their rough surface, which has a high surface area, intensifies the uncontrollable growth dendrites parasitic side reactions. In this study, an anti‐corrosive Zn‐P‐based anode functional layer formed from MXene Cu‐THBQ (MXene/Cu‐THBQ) heterostructure is successfully fabricated via microfluidic‐assisted 3D printing. The unusual strong adsorption ions using MXene/Cu‐THBQ can effectively homogenize ion flux inhibit hydrogen evolution reaction (HER) during repeated process plating/stripping, thus achieving stable cycling. Consequently, symmetric cell based on Zn‐P exhibits highly reversible cycling 1800 h at 2 mA cm −2 /1 mAh . Furthermore, Zn‐organic full battery matched 4‐hydroxy‐2,2,6,6‐tetramethylpiperidine‐1‐oxyl organic cathode riveted graphene delivers capacity maintains long cycle life.

Abstract Hydrogel electrolytes (HEs), characterized by intrinsic safety, mechanical stability, and biocompatibility, can promote the development of flexible aqueous zinc‐ion batteries (FAZIBs). However, current FAZIB technology is severely restricted uncontrollable dendrite growth arising from undesirable reactions between HEs with sluggish ionic conductivity Zn metal. To overcome this challenge, work proposes a molecular engineering strategy, which involves introduction oxygen‐rich poly(urea‐urethane) (OR‐PUU) into polyacrylamide (PAM)‐based HEs. The OR‐PUU/PAM facilitate rapid ion transfer through their hopping migration mechanism, resulting in uniform orderly 2+ deposition. abundant polar groups on OR‐PUU molecules break inherent H‐bond network, tune solvation structure hydrated , inhibit occurrence side reactions. Moreover, interaction hierarchical H‐bonds endows them self‐healability, enabling situ repair cracks induced plating/stripping. Consequently, symmetric cells incorporating novel exhibit long cycling life 2000 h. Zn–MnO 2 battery displays low capacity decay rate 0.009% over cycles at mA g −1 .
