Aqueous zinc (Zn) ion batteries have received broad attention recently. However, their practical application is limited by severe Zn dendrite growth and the hydrogen evolution reaction. In this study, three alkali metal ions (Li+, Na+, K+) are added in ZnSO4 electrolytes, which subjected to electrochemical measurements molecular dynamics simulations. The studies show that since K+ has highest mobility self-diffusion coefficient among four K+, Zn2+), it enables preferentially approach a at an earlier time, driven negative electric field during cathodic process. double layer, with around negatively charged dendrite, inhibits mitigates reaction on anode. Under kinetic effect, Zn-Zn symmetric cell exhibits long cycling stability of 1000 h 1 mA·cm-2 mAh·cm-2 190 30 2 mAh·cm-2. Such effect also observed additives Na+ Li+, though less profound than K+.

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 . Overall, provides valuable insights to realization dendrite‐free Zn‐metal anodes

Abstract The uneven texture evolution of Zn during electrodeposition would adversely impact upon the lifespan aqueous metal batteries. To address this issue, tremendous endeavors are made to induce Zn(002) orientational deposition employing graphene and its derivatives. Nevertheless, effect prototype film over behavior has garnered less attention. Here, it is attempted solve such a puzzle via utilizing transferred high‐quality with controllable layer numbers in scalable manner on foil. multilayer fails facilitate epitaxial deposition, whereas monolayer slight breakages steers unique pinhole mode. In‐depth electrochemical measurements theoretical simulations discover that not only acts as an armor inhibit side reactions but also serves buffer homogenize initial nucleation decrease migration barrier, accordingly enabling smooth closely stacked polycrystalline domains. As result, both assembled symmetric full cells manage deliver satisfactory performances. This study proposes concept “pinhole deposition” dictate broadens horizons graphene‐modified anodes.
