Abstract

Microsized Sn presents stable cyclic performance in a glyme-based electrolyte, which brings 19% increase in energy density of Sn/Na<sub>3</sub> V<sub>2</sub> (PO<sub>4</sub> )<sub>3</sub> cells as compared to the cells using a hard carbon anode. The NaSn intermediate phases are also clarified.
