Abstract Renewable energy‐powered seawater electrolysis is a green and attractive technique for producing high‐purity hydrogen. However, severe chlorideions (Cl − ) their derivatives tend to corrode anodic catalysts at ampere‐level current densities hinder the application of seawater‐to‐H 2 systems. Herein, polycalmagite (PCM)‐coated NiFe layered double hydroxide presented on Ni foam (NiFe LDH@PCM/NF) that exhibits exceptional stability in alkaline seawater. PCM not only acts as conductive layer reduce charge transfer resistance anodes but also polymer‐based protective inhibit Cl adsorption stabilize metal ions oxidation due its own anions strong adhesion, thereby increasing activity during Thus, LDH@PCM/NF needs low overpotential 364 mV reach up 1000 mA cm −2 maintains operation 500 h without degradation. Moreover, minimal amount hypochlorite can be detected electrolyte after 500‐h test. This development affords significant exploration creating durable efficient anodes, highlighting importance polymer coating toward anti‐corrosion oxidation.
