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
In order to further enhance the reversible capacity and cyclability for lithium storage of Sn-based alloy anode materials, a spherical-shaped Sn-FeO@C ternary-phase composite consisting of nanosized tin (Sn), magnetite (FeO), and graphite (C) was prepared via a two-step process using high-efficiency discharge plasma-assisted milling (P-milling). Ultrafine Sn nanoparticles were embedded and tightly contacted with nanosized FeO, with graphite nanosheets coating the outside to form a multiscale spherical structure. The Sn-FeO@C nanocomposite anodes demonstrate a stable and high capacity of 793 mA h g after 240 cycles between 0.01 and 3.0 V vs. Li/Li at 200 mA g. Furthermore, a reversible capacity of ∼750 mA h g was obtained after 500 cycles, even when the current density increased to 2000 mA g. The high capacity, good cycle performance, and superior high-rate capability characteristics were attributed to the unique nanostructure of the Sn-FeO@C composites. The good dispersion of co-existing Sn and FeO nanoballs in a spherical carbon matrix resulted in an electrode with high structural stability and fast kinetics for Li ion and electron transfer, which contributed to high reversibility of alloying reactions in Sn and conversion reactions of FeO. Furthermore, the spherical shape of the materials and simple preparation as compared to those of commercial anodes make the Sn-FeO@C composites good candidates for practical applications.
