Sediment Microbial Fuel Cell (SMFC) technology is an innovative approach to facilitate the degradation of sedimentary organic matter by electroactive microorganisms, transforming chemical energy into electrical energy and modulating the redox potential at the sediment-water interface, consequently controlling the release of endogenous pollutants. The synergistic effects of various environmental factors and intrinsic conditions can significantly impact SMFC performance. This review provides a comprehensive overview of SMFC development in research and application for water environment treatment and ecological remediation, a perspective rarely explored in previous reviews. It discusses optimization strategies for SMFC implementation, emphasizing advancements in novel or cost-effective electrode materials, the dynamics of microbial communities, and the control of typical pollutants. The review suggests a virtuous cycle path for SMFC development, highlighting future research needs, including integrating cross-disciplinary approaches like artificial intelligence, genomics, and mathematical modeling, to enhance the deployment of SMFC in real-world environmental remediation.
