Summary
The oceans hold abundant resources, and marine clean energy plays a significant role in achieving the Sustainable Development Goals (SDGs). However, pronounced corrosion, pervasive biofouling, and complex hydrodynamic conditions in the marine environment present major challenges to the long-term reliability of energy conversion, harvesting, and storage systems. As a critical component, electrode materials must combine high electrochemical performance with resistance to marine corrosion and fouling, and meet environmental criteria such as low toxicity and recyclability. Thus, their development is inherently interdisciplinary. For example, triboelectric nanogenerators (TENGs) show promise for self-powered ocean sensors and environmental monitoring but still face challenges in power density, long-term durability, and scale-up. Microfluidic techniques provide powerful laboratory-scale platforms for studying novel harvesting mechanisms and interfacial transport, while computational fluid dynamics, numerical modeling, and machine learning open new opportunities to reveal complex mechanisms, predict lifetime, and accelerate materials design. In-depth research on electrode materials tailored for marine clean energy is therefore essential for sustainable green energy development and marine environmental protection, and is expected to provide key support for green development of the oceans.
This special issue aims to assemble the latest research advances in electrode materials for marine clean-energy development, to probe the underlying scientific questions and engineering challenges, and to spotlight innovative designs, performance optimization, and demonstrative applications of electrode materials that advance marine clean-energy deployment and environmental sustainability.
Topics of interest include, but are not limited to, the following:
· Development of novel nanoarchitectures, composites and green synthesis methods to improve electrochemical performance and environmental compatibility
· Coatings, surface functionalization and self-cleaning strategies for marine corrosion and biofouling mitigation, including durability assessment
· Batteries, supercapacitors, fuel cells and electrode behavior, performance and degradation mechanisms under seawater conditions
· Material optimization and field demonstrations of TENGs, piezoelectric and hydrodynamic harvesters for ocean deployment
· Microfluidics, in-situ characterization and theoretical models to probe interfacial transport and multiphysics coupling
· Use of CFD, lifetime prediction and data-driven approaches to accelerate material screening and system optimization
· Low-carbon manufacturing, recyclable material design and environmental impact quantification
· Self-powered sensors, electrode health monitoring, remote diagnostics and AI-based maintenance strategies
· Focus on life-cycle assessment (LCA) of materials and devices, ecotoxicity, bioaccumulation, circular design, ecological impacts and restoration strategies
· Economic feasibility, regulatory frameworks, risk assessment and sustainable pathways for marine energy deployment
