The article titled "Dissolution Mechanism for Dendrite-Free Aqueous Zinc-Ions Batteries" discusses the issue of dendrite growth in zinc-ion batteries, which affects their cycling stability. The authors, Hou Ian, Junpeng Xie, Guo Hong, and their colleagues, propose the use of adsorptive additives to manipulate zinc dissolution and achieve smooth morphological evolution throughout the battery cycles. This research aims to address the challenges associated with zinc deposition and dissolution in order to improve the performance of zinc-ion batteries. [Extracted from the article]

Aqueous zinc ion batteries coupling with conventional hydrogel electrolyte have the advantages of high safety, low cost, and simple manufacturing process while they are difficult for fast charging/discharging application scenarios due to the sluggish kinetics. Herein, a new strategy is developed for synthesizing a highly‐entangled polyacrylamide (HE‐PAM) hydrogel electrolyte to dramatically enhance the ion transportation and mechanical stability. The developed hydrogel electrolyte has lower ionic resistance and a strong elastic modulus. After being assembled into Zn/MnO2 batteries, the HE‐PAM hydrogel electrolyte exhibits excellent cycling stability and high‐rate capability under high current densities. Specifically, the Zn//HE‐PAM//MnO2 battery can resist the highest current of 35 A g−1, which outperforms previously reported works. Moreover, the HE‐PAM hydrogel electrolyte can also support the fast charging/discharging in proton ion batteries with a high capacity retention rate of 50% under 50 A g−1. This progress on hydrogel electrolytes can boost the development of quasi‐solid‐state batteries in the fast charging/discharging aspect. [ABSTRACT FROM AUTHOR]
