This work may provide a reliable strategy for designing dendrite-free, high-performance, zinc host materials with highly wetting interfaces.

Moreover, the assembled full-cell with foam as the anode and α-MnO2 nanowire as the cathode delivers a stable discharge specific capacity of 181.8 mAh g-1 at 2 A g-1 over 3000 cycles. As a result, the Cu foam as a well-wettable and zincophilic host shows a mosslike dendrite-free plating/stripping process with a small nucleation overpotential (19.5 mV) and an ultra-stable lifespan of 3000 h at 1 mA cm-2 and 1 mAh cm-2 in zinc symmetrical batteries. It is found that the Cu foam host can not only offer extra zincophilic nucleation sites by increasing surface area, but also guide a uniform ion distribution due to capillary-like effect induced by the arrangement of numerous copper nanowires.

Herein, nanowire-decorated Cu foam (Cu foam) with good wettability and zinc affinity was fabricated to enhance the reversibility of electroplating/electrostripping. Firstly, you must download Turbo C++ from the link: Turbo.C.3.2. Designing three-dimensional host material as the substrate is an effective approach to enhance the highly reversible plating/stripping behavior of Zn anode. However, the practical application of Zn anode is still impeded by the growth of dendrites during Zn plating/stripping process. Metallic Zinc (Zn), with high safety, low cost, and environmental friendliness, is deemed as a promising anode for aqueous zinc-ion batteries.
