Foldable and free-standing 3D network electrodes based on cellulose nanofibers, carbon nanotubes and elongated TiO2 nanotubes
Foldable and free-standing electrodes were fabricated using the macroporous cellulose nanofibers(CNFs)as the scaffold.Multi-walled carbon nanotubes(MCNTs)wrapped around the CNFs as the conductive skin,while the elongated(tens of microns)TiO2 nanotubes(TNTs)were interpenetrated within the MCNTs and macroporous CNFs network.Electrochemical analysis indicated that the hybrid electrodes displayed a high discharge capacity of 62.5 mF/cm2 at 10 mV/s and a good cyclability with a capacity loss 5%after 1000 cycles at 0.5 mA/cm2.The hybrid electrodes possessed highly mechanical property and could be folded back and forth as a paper airplane without mechanical failure.Therefore the low-cost,light-weight and foldable electrodes can be well applied as foldable all-solid-state supercapacitors.
