A systematic overview of dealloying technique in electrochemical energy storage is presented. [Display omitted] •A review specialized dealloying technique in energy storage.•Characters, fundaments, and advantages of dealloying technique.•Dealloying techniques, including chemical, electrochemical, and vapor dealloying.•0D, 1D, 2D, and 3D materials fabricated by dealloying technique.•Applications, challenges and future development of dealloying technique in energy storage. Nanomaterials have promising applications in catalysis, filtration, hydrogen storage, sensors, automobile exhaust treatment, and energy storage and conversion, etc. However, scalable and economic fabrication of nanomaterials remains a challenge. In the past century, the world has witnessed successful industrialization of nanoporous Raney nickel in thousands of tons per year by dealloying method. With the advantages of low cost, scalable fabrication and controllable structure, dealloying technique has attracted more attention and gained wider applied in numerous areas. This review attempts to summarize the recent progress in development of dealloying technique, with special emphasis on synthetic materials (0D, 1D, 2D, 3D) and advanced applications, including lithium-ion batteries, lithium-oxygen batteries, lithium-sulfur batteries, lithium-metal batteries, zinc-metal batteries, sodium-ion batteries, magnesium-ion batteries, potassium-ion batteries, aluminum-ion batteries, aluminum-carbon dioxide batteries, and supercapacitors, etc. The advantages, theoretical research, and influence factors of dealloying technique are also analyzed. Besides, key scientific issues and prospective directions of dealloying technique are also discussed. We believe this review may attract more researchers in relevant fields and offer some guide for the future development of dealloying technique.
