摘要：

A SnP3 anode material with a theoretical volumetric capacity of 6890 mAh cm-3 is investigated for Na-ion batteries. The SnP3/C can deliver a reversible capacity of 810 mAh g-1 at a current density of 150 mA g-1 for 150 cycles. The superior performance is attributed to the strong bonding interaction of P and Sn after desodiation. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
