Electrodeposition of pure phase SnSb exhibiting high stability as a sodium-ion battery anode

Abstract

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.
