Abstract: Tin powder is widely used in industry as a raw material for making various products. In this study, the tin powder is prepared by electrodeposition of a mixed solution of tin chloride with a deep eutectic solvent as the electrolyte, to investigate the impact of electrodeposition variables on the current efficiency and the tin morphology produced at the surface of the stainless steel 316 cathode. A cyclic voltammetry test was applied to observe the characteristics of the electrolyte solutions, and the electrodeposition experiment was applied to investigate the impact of technological variables on current efficiency and tin morphology formed at the stainless 316 cathode surface. Experimental findings show that in the cyclic voltammetry test, increasing the tin amounts in electrolyte solutions from 5 to 30 g L−1 increased the cathodic peak current, and the higher tin amount creates a higher current density. While in the electrodeposition process, the cathode current efficiency increased when the electrodeposition current was raised from 2.5 to 6.88 A dm−2 or the tin amounts in the electrolyte solution were raised from 5 to 10 g L−1. Additionally, smaller tin particles were produced at a higher current density, lower temperature, and lower tin amount.
