Graphical Abstract

A simple and fast melting-solidification approach was developed to effectively convert commercial Zn foils into single (002)-textured Zinc with millimeter-sized (eye-visible) grains. The single (002) texture and huge grain features ensure large-scale epitaxial Zn deposition and significantly minimize the intergranular reactions, resulting in impressive reversibility of Zn metal anode in both Zn||Zn symmetric cells and full cells.

Abstract

Rechargeable aqueous zinc batteries are promising but hindered by unfavorable dendrite growth and side reactions on zinc anodes. In this study, we demonstrate a fast melting-solidification approach for effectively converting commercial Zn foils into single (002)-textured Zn featuring millimeter-sized grains. The melting process eliminates initial texture, residual stress, and grain size variations in diverse commercial Zn foils, guaranteeing the uniformity of commercial Zn foils into single (002)-textured Zn. The single (002)-texture ensures large-scale epitaxial and dense Zn deposition, while the reduction in grain boundaries significantly minimizes intergranular reactions. These features enable large grain single (002)-textured Zn shows planar and dense Zn deposition under harsh conditions (100 mA cm−2, 100 mAh cm−2), impressive reversibility in Zn||Zn symmetric cell (3280 h under 1 mA cm−2, 830 h under 10 mAh cm−2), and long cycling stability over 180 h with a high depth of discharge value of 75 %. This study successfully addresses the issue of uncontrollable texture formation in Zn foils following routine annealing treatments with temperatures below the Zn melting point. The findings of this study establish a highly efficient strategy for fabricating highly reversible single (002)-textured Zn anodes.
