Abstract
Sodium-ion batteries (SIBs) are developed to address the serious concern about the limited resources of lithium. To achieve high energy density, anode materials with a large specific capacity and a low operation voltage are highly desirable. Herein, microsized particles of gray Sn (α-Sn) are explored as an anode material of SIBs for the first time. The distinct structure of α-Sn endows it the reduced volume change, the improved interaction with polymer binders and the in situ formation of amorphous Sn, as supported by in situ XRD, TEM and DFT calculations. Therefore, α-Sn exhibits an excellent electrochemical performance, much better than β-Sn widely used before. Even microsized particles of α-Sn without any treatments deliver a capacity of ∼451 mAh g-1 after 3500 cycles at 2 A g-1 or ∼464 mAh g-1 at 4 A g-1 in a rate test. The results indicate the promising potential of α-Sn in SIBs.

Abstract
We explore the applicability of graphynes, two-dimensional carbon sheets with sp- and sp2-bonds, as sodium (Na)-ion battery anodes using first-principles density functional theory. We found that voltages attainable from the charging-discharging of Na into multilayer graphyne are proper for use as anodes. The composite is ∼C6Na2 at the maximum Na concentration, corresponding to gravimetric and volumetric capacities of ∼837 mAh g-1 and ∼1056 mAh cm-3, respectively. These are significantly greater than the corresponding values (372 mAh g-1 and 818 mAh cm-3) of graphite for lithium. We ascribe the enhancement of the capacities to their nanoporous structures with sp- and sp2-bonded carbon atoms, which effectively bind multiple Na atoms. We propose that sp-sp2 carbon sheets can be promising candidates for high-capacity Na-ion battery anodes.
