首次报道了纯相SnSb的电沉积。产品的纯度很重要，因为发现不纯的相对材料作为钠离子阳极的寿命是有害的。直接沉积的电极在300次循环后能够保持95%的容量，并且当相对于钠循环时，在800次循环后仅下降到低于80%的容量保持率。
Electrodeposition of pure phase SnSb is reported for the first time. The purity of the product is important, as the impure phase is found to be detrimental to the material's lifetime as a sodium-ion anode. The directly deposited electrode was able to retain 95% capacity after 300 cycles, and only fall below 80% capacity retention after 800 cycles when cycled versus sodium.
