Embedding Reduced Graphene Oxide in Bacterial Cellulose‐Derived Carbon Nanofibril Networks for Supercapacitors

A simple, effective, eco‐friendly, and scalable reduced graphene oxide embedding strategy is developed to construct self‐supported carbon electrode material networks for supercapacitors from a naturally occurring biomaterial−bacterial cellulose. The thus‐engineered self‐supported carbon nanofibril networks exhibit superior supercapacitive performance compared to their counterparts, thus opening up an avenue to design self‐supported high‐capacitance carbon electrode materials toward high‐class supercapacitors.
