Abstract
Sn4 P3 is introduced for the first time as an anode material for Na-ion batteries. Sn4 P3 delivers a high reversible capacity of 718 mA h g(-1), and shows very stable cycle performance with negligible capa-city fading over 100 cycles, which is attributed to the confinement effect of Sn nanocrystallites in the amorphous phosphorus matrix during cycling.
摘要
首次将 Sn4 P3 用作钠离子电池的阳极材料。Sn4 P3 提供了高达 718 mA h g(-1)的高可逆容量，并具有非常稳定的循环性能，在 100 次循环中几乎没有容量衰减，这归因于 Sn 纳米晶在循环过程中被无定形磷基体限制。
