Practical, sustainable, wide-temperature-adaptable zinc-metal batteries enabled by electrogelated recyclable biomacromolecular hydrogel electrolytes.

ABSTRACT: In the promotion of aqueous zinc (Zn)-metal batteries, hydrogel electrolytes have been found to come with the capability to physically obstruct dendritic Zn growth and suppress unwanted side reactions compared to their liquid counterparts. However, due to the opposite structural requirements for ionic conductivity and mechanical strength, the preparation of thin-film hydrogel electrolytes for energy-dense Zn-metal batteries remains a formidable task. Herein, electrogelation that offers several unique advantages, including precise control over the thickness, good geometric adaptability, and high tunability of the hydrogels' microstructures and properties, is investigated as a promising technique to address the above-mentioned dilemma. It is shown that, by varying the electrogelation paramet
