Sn 4 P 3 is introduced for the first time as an anode material for Na‐ion batteries. Sn 4 P 3 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.
