Abstract

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.
