Abstract
A method for electrodeposition of pure phase crystalline SnSb from deep eutectic ethaline is described. Thin films of SnSb were synthesized using a solution containing equimolar Sn(II) and Sb(III) chlorides as precursors, and ethaline (1:2 by weight of choline chloride and ethylene chloride) was used as the solvent for the electrodeposition solution. The purity of the product is important, as the impure phase is found to be detrimental to the material's lifetime as both a sodium-ion and a lithium-ion anode. For sodium-ions, 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. The electrodeposited SnSb used as a Li-ion battery anode showed stability, only falling below 80% capacity retention after 400 cycles.
