The structure, morphology, and composition of electrode materials play a crucial role in determining the electrochemical performance of energy storage devices. Among various materials, three‐dimensional (3D) porous carbon stands out for its potential to enhance electrochemical energy storage due to its cost‐effectiveness, excellent ion and electron conductivity, abundant active sites, and customizable pore structure. The salt‐template method offers an environmentally friendly, fast, and cost‐efficient approach to synthesizing 3D porous carbon, with the added advantage of adjustable pore architecture and composition. This review provides a comprehensive overview of recent advancements in preparing 3D porous carbon and its composites using the salt‐template method, emphasizing their applications in batteries and supercapacitors. It also critically examines the existing challenges and explores potential future directions for further development in this field.
