“…Evidently, the specific capacitance of CNF-rGO-NiCoLDH (3620.5 mF cm −2 ) is the highest compared to those of CNF-GO-NiCoLDH (2132.4 mF cm −2 ) and NiCoLDH (1416.2 mF cm −2 ) at 2 mA cm −2 (Figure 5e). The specific capacity of CNF-rGO-NiCoLDH is significantly higher than those of the recently reported electrode materials (Table S3), such as GO/poly(3,4-ethylenedioxythiophene) (PEDOT)-lCNTs (100.3 mF cm −2 at 0.5 mA cm −2 ), 59 polyaniline (PANI):poly(sodium 4-styrene sulfonate) (PSS)/CNF-4 (2560.0 mF cm −2 at 2 mA cm −2 ), 60 single-walled carbon nanotube (SWCNT)/cellulose/PANI (330.0 mF cm −2 at 0.2 mA cm −2 ), 61 Ag NW@NiCo/NiCo(OH) 2 (22.2 mF cm −2 at 0.1 mA cm −2 ), 62 H-NiCoLDH@ACC (3060.0 mF cm −2 at 1 mA cm −2 ), 63 NiCoLDH@GSs@CF-NF (1729.4 mF cm −2 at 1 mA cm −2 ), 64 Ni 0.54 Co 0.46 O 2 nanosheet (3510.0 mF cm −2 at 1 mA cm −2 ), 65 and NCNTFF-NiCo 2 O 4 (2430.4 mF cm −2 at 2 mA cm −2 ). 66 Moreover, we further study the influence of rGO content on the structure and electrochemical performance of CNF-rGO-NiCoLDH.…”

The weak stiffness, huge thickness, and low specific capacitance of commonly utilized flexible supercapacitors hinder their great electrochemical performance. Learning from a biomimetic interface strategy, we design flexible film electrodes based on functional intercalated structures with excellent electrochemical properties and mechanical flexibility. A composite film with high strength and flexibility is created using graphene (reduced graphene oxide (rGO)) as the plane layer, layered double metal hydroxide (LDH) as the support layer, and cellulose nanofiber (CNF) as the connection agent and flexible agent. The interlayer height can be adjusted by the ion concentration. The highly interconnected network enables excellent electron and ion transport channels, facilitating rapid ion diffusion and redox reactions. Moreover, the high flexibility and mechanical properties of the film achieve multiple folding and bending. The CNF-rGO-NiCoLDH film electrode exhibits high capacitance performance (3620.5 mF cm −2 at 2 mA cm −2 ), excellent mechanical properties, and high flexibility. Notably, flexible all-solid assembled CNF-rGO-NiCoLDH//rGO has an extremely high area energy density of 53.5 mWh cm −2 at a power density of 1071.2 mW cm −2 , along with cycling stability of 89.8% retention after 10 000 charge−discharge cycles. This work provides a perspective for designing high-performance energy storage materials for flexible electronics and wearable devices.
