With the rapid development of wearable technology, the demand for flexible lithium batteries is increasing. The combination of active electrode materials with excellent electrochemical properties and flexible nano-carbon-based materials is a hot research direction for the preparation of high-performance flexible lithium battery electrodes. In this paper, the research and application of carbon fiber and fabric in flexible electrode materials of lithium ion and lithium sulfur battery were reviewed. The different methods and progress of preparing flexible composite electrode materials are summarized, including electrospinning technology, hydrothermal method, heat treatment, coating, magnetron sputtering, atomic layer deposition and thermal etching. All of the obtained electrode materials show excellent performance in some aspects, such as high reversible capacity, excellent cycle performance, and enhanced mechanical strength, etc. Finally, the prospect of the development of flexible lithium battery electrodes based on carbon fiber and fabric was put forward.
