Recent Progress in Flexible Biomass‐Derived Carbon‐Based Electrodes for Rechargeable Batteries

Biomass-derived carbons have been widely researched as matrix components of catalysts in electrodes of various rechargeable batteries. In recent years, in order to meet the huge demand for wearable devices, high-performance flexible rechargeable batteries have been developed, and great progress has been made. This review systematically outlines the preparation and modification of flexible biomass-derived carbon and flexible biomass-derived carbon-based electrodes, as well as their applications in different types of flexible rechargeable batteries. In light of the current development of flexible rechargeable batteries, this review identifies key challenges and proposes potential solutions for flexible biomass-derived carbon-based electrodes. It thereby offers valuable insights and practical guidance for the rational design and fabrication of these sustainable electrode materials.
