“…Table S5 compares the specific capacitance, rate performance and cycling ability of the current work with those of previously PANI-based composite electrodes, such as AgCl intercalated RGO-PANI, graphene/PANI, RGO/C-PANI, PANI/MHCF/CF, and 20%-GO@MSNs/PANI . It can be found that the holey graphene/PANI/graphene nanohybrid in this work displays a relatively high specific capacitance, an ultrahigh-rate retention and a comparable cycling performance.…”

Hierarchically porous holey graphene/PANI/ graphene nanohybrid is fabricated by adopting a facile twostep process in which PANI/graphene hybrid was first synthesized hydrothermally and then wrapped with a layer of holey graphene. The resulted sandwich-like structure cannot only promote electronic transmission and ionic diffusion, but also contribute to a prominent rate capability. A symmetric supercapacitor was assembled with the obtained holey graphene/PANI/graphene nanohybrid, exhibiting a maximum specific capacitance of 437 F•g −1 at 1 A•g −1 , an energy density of 55 Wh•kg −1 at 900 W•kg −1 , an ultrahigh-rate performance (retained 43% capacitance at 100 A•g −1 ), as well as a long-term life (84% retention after 5000 loops at 10 A•g −1 ). The present work may provide an insight for designing highperformance symmetric supercapacitor.

“…Not only for its appealing electrochemical properties, but sustainable energy-based applications such as lithium-ion batteries, fuel cells, and supercapacitors (SCs) are also energy-based applications such as lithium-ion batteries, fuel cells, and supercapacitors (SCs) are currently being super-developed. SCs have a significant advantage over LiBs, including higher power densities, longer life spans, and fast charge-discharge abilities [8,9]. Generally, Supercapacitors are classified according to storage mechanism into three types double-layered capacitors, pseudocapacitors, and battery-type capacitors, based on their energy storage strategies [10][11][12][13][14][15].…”

The target for developing electrode materials with unique architecture and tailored composition is essential for influencing their electrochemical properties. The innovative porous zinc cobalt sulfide (ZnCo2S4/ Ni foam (NF)) nanocoral reef-like structure supported by 3D NF is fabricated by the hydrothermal method. Here is an advanced electrode for supercapacitors (SCs), which demonstrates the notable electrochemical performance of the electrode in terms of the specific capacity of 2055.2 C g -1 (specific capacitance of 1957.4 F g -1 ) at 1 A g -1 and excellent cyclic stability of 89.2% capacity retention and 98% coulombic efficiency after 5000 cycles. Furthermore, the battery-type symmetric supercapacitors based on ZCS/NF have an ultrahigh energy density of 39.1 Wh kg -1 at a power density of 1637 W kg -1 with excellent cyclic stability, 93.3% capacity retention, and 100% coulombic efficiency after 6000 cycles. The outstanding characteristics can be attributed to the synergistic contribution of the ZnCo2S4/NF coral reef hierarchical architecture and the bimetallic sulfide with great valence states for rich redox reactions. Therefore, the nano coral reef ZnCo2S4/NF is promising electrode material for battery-type supercapacitors.

“…The presence of water facilitates the conduction of polyaniline. 7,18 Nechtschein 19 reports that the conductivity of polyaniline increases with the increase of water absorption. The electrons leap from the reduced benzene ring to the oxidized quinone structure of polyaniline, while the small molecule water transforms between the two structures to achieve conductive enhancement.…”

A new method to improve the performance of Prussian blue sodium ion supercapacitors by polyaniline coating is presented. The conducting mechanism of polyaniline film facilitates small water molecules transforming between benzene structure and quinone structure of polyaniline, which minimizes lattice water content of NiCo-Prussian blue analogues materials. The polyanilinecoated NiCo-Prussian blue analogues are loaded on carbon sponge material to assemble flexible supercapacitors. The specific capacity of 118.2 F g −1 , energy density of 32 Wh kg −1 , and power density of 6.
