The structural designability of organic materials lays an optimal foundation for comprehensive energy‐storage applications, owing to their selectivity of functional groups, diversity of linkage modes, and operability of synthesis conditions. Covalent organic frameworks (COFs), as a notable ordered porous framework structure, can provide a specific direction for ion diffusion as well as control the amount and location of redox sites, which are believed to be potential energy‐storage or ion‐transport carriers. In this study, a systematic overview of COFs for battery application is provided by conducting a comprehensive analysis and offering objective comments on the plasticity of the dominant structure and the improvement of the electrochemical properties. In addition, the existing problems and corresponding solutions of COFs for different devices are elaborated, and future research directions and application prospects of COFs are proposed. This review would provide theoretical guidance for alternative energy‐storage materials and widen the applications of such promising materials for next‐generation energy‐storage devices.
