Recently, flexible lithium-ion batteries (LIBs) have gained attention due to the demand for rechargeable batteries that can operate stably despite external bending or stretching. Current commercially available LIBs mainly use heavy and brittle inorganic electrode which is typically not suitable for flexible devices. Organic materials are promising electrode materials because they have various advantages such as low cost, light-weight, and environmentally friendly property. In this study, we have developed a flexible organic cathode for LIBs based on a perylene-based molecules as active material, carbonized cotton fiber (CCF) as a conductive agent and a polymeric matrix support. The cathode was fabricated using a solution-based phase inversion without any metal current collector or binder. The CCF cathode exhibits excellent electrochemical performance and mechanical stability, showing the possibility of high-performance flexible organic electrodes. |
