Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Rechargeable aqueous zinc (Zn) batteries have attracted great interests because of its inherent safety and cost-effectiveness. However, the uncontrollable Zn dendrite formation in aqueous electrolyte restricts its reversibility for long-life application. The bulge or passivation layer in pristine Zn surface serves as nuclei for large amount of Zn crystal aggregation and inhomogeneous Zn electrodeposition. Here, for the first time, we demonstrate a simple, effective, and non-corrosive electropolishing strategy to develop a smooth and clean Zn metal as compared with burdensome and unreliable mechanical polishing method in lab-scale research. After removing the primitive passivation layer, the fresh Zn anode can survive at a high current density of 40 mA cm −2 over 6000 times. Moreover, the electropolished Zn gains more consistent and reliable electrochemical behaviors which contributes to study the mechanism of Zn electrodeposition and clarify the effectiveness of protective strategies in the follow research.
