Influence of Electrode Morphology on Metal Deposition in Electrowinning
The morphology form of the electrode plays a vital role in influencing the efficiency and quality of metal deposition during electrowinning processes. A variety of factors, including electrode material, surface roughness, and applied potential, contribute to the formation of distinct deposit morphologies.
