Abstract
Sn4P3 is introduced for the first time as an anode material for Na-ion batteries. Sn4P3 delivers a high reversible capacity of 718 mA h g-1, and shows very stable cycle performance with negligible capacity fading over 100 cycles, which is attributed to the confinement effect of Sn nanocrystallites in the amorphous phosphorus matrix during cycling. © 2014 WILEY-VCH Verlag GmbH & Co.
