Recent progress in carbon nanomaterials for highly flexible fibrous aqueous zinc-ion batteries

Fibrous zinc-ion batteries (FZIBs) are ideal wearable energy storage devices with unparalleled utility in the next generation of flexible electronics. However, the conventional electrode materials still present challenges to achieve both good electrochemical performance and mechanical deformability. This hinders their large-scale production and commercial application. Carbon nanomaterials exhibit a number of advantageous properties, including high chemical stability, high conductivity, low cost, and high mechanical flexibility. These characteristics make them an attractive option for modifying electrode materials. This review presents an overview of the latest research developments and practical applications of carbon nanomaterial-assisted FZIBs cathodes and anodes. It also identifies the key challenges currently limiting the performance of high-performance FZIBs and outlines potential future research directions.
