The Cover Feature shows a flexible supercapacitor device fabricated using an electrode composed of lignin‐containing cellulose nanofibrils, reduced graphene oxide, and polyaniline. The natural lignin that is covalently bound to the surface of the cellulose nanofibrils improved the charge storage performance of the electrode. These improvements were explained by the quinone/hydroquinone functional groups in lignin that enable redox reactions to contribute additional pseudocapacitance.
