<p>Functional modification of metal surfaces is a key strategy for enhancing the properties of metal matrices. Superhydrophobic coatings on metal surfaces, achieved through surface modification, have gained significant attention for their anticorrosion, antifouling, anti-icing, and antibacterial properties. Electrochemical technology stands out among various methods for preparing these coatings due to its simple process, high controllability, large-scale applicability, and uniform coating. This paper reviews electrochemical methods for preparing superhydrophobic coatings, emphasizing current applications and theoretical advancements. The paper first categorizes electrochemical techniques for superhydrophobic coatings and summarizes their applications. It then addresses the limitations of electrochemical methods in practical use and identifies gaps in theoretical research based on the current literature. Solutions to these challenges are proposed. Finally, new research directions are suggested, and the prospects for electrochemical preparation of superhydrophobic coatings on metal surfaces are explored.</p>
