“…The small semicircle in the high-frequency region reflects the fast charge transfer rate at the electrode/electrolyte interface [60]. The narrower the diameter of the semicircle, the smaller the total resistance (impedance) and the higher the electrical conductivity [59,61].…”

“…In this analysis, there are generally two parts that are generated in the Nyquist plot, i.e. a semicircle segment in the high-frequency region and a sloping line in the low frequency region [59]. The diameter of the semicircle in the high-frequency region is positively correlated with the charge transfer resistance (R ct ) while the intercept on the X-axis represents the internal resistance (R s ).…”

Bismuth oxide/commercial activated carbon/graphite composite was successfully synthesised using the hydrothermal method with time variations and characterisation using Fourier Transform Infrared Spectroscopy, X-ray Diffraction, Scanning Electron Microscopy-Energy Dispersive X-ray mapping, Gas Sorption Analyzer, and battery performance tests including analysis of electrical conductivity, charge–discharge, and cyclic voltammetry. The formation of bismuth oxide is indicated by the presence of Bi-O and Bi-O-Bi groups and the presence of α-Bi2O3 crystal structure. In addition, based on SEM mapping, bismuth oxide particle is well distributed on the composite having rod-like shape morphology. The best electrochemical behaviour is shown by composite synthesised longer that is 1.35 × 10−2 S.m−1, 285.882 mAhg-1, 131.745 mAhg−1 for electrical conductivity, charge specific capacity, and discharge specific capacity, respectively. These results open a way for the composite as Li-ion battery anode.

“…Metal oxides are the most common catalysts in different electrochemical energy conversion reactions. Many works have been done to enhance the performance of metal oxides by introducing a carbon support [71,72] . Unsurprisingly, researches on the application of GDY as a support material have been carried out immediately since it was first reported.…”

raphdiyne(GDY), which is composed of sp 2 -/sp-hybridized carbon atoms, has attracted increasing attention. In the structure of GDY, the existence of large triangular-like pores, well dispersed electron-rich cavities as well as a large π-conjugated structure endows GDY with a natural bandgap, fast electron/ion transport, and tunable electronic properties. These unique features make GDY competitive in areas of gas separation and capture, electronics, detectors, catalysts, biomedicine and therapy, and energy-related fields. Benefiting from the facile synthesis method, various GDY structures and GDY-based composites have been successfully prepared and show great potential in the practical application of energy storage and catalysis areas. Here, this review aims at providing a timely and comprehensive update on the preparation and application of GDY materials. The current development of GDY materials in various electrochemical fields especially in energy conversion, energy storage, and catalysis is mainly summarized. Moreover, the potential development prospects are also discussed.

“…[7][8][9][10][11] Another strategy is to prepare carbon modified NiO/carbon composites to improve the electronic conductivity and limit volume expansion. [12,13] So far, various carbon materials have been adopted, including the commercial carbon (graphene, CNT) and organic compounds derived carbons (such as glucose, citric acid, urea, etc.,), to modify the properties of NiO/C composite materials to achieve better electrochemical performances than pristine NiO. [14][15][16][17][18][19] However, on the one hand, the organic compounds derived carbons cannot possess as good electric conductive as typical CNTs or graphene and the thickness of coating layers is difficult to be controlled.…”

The blooming requirement of high‐performance energy storage systems has aroused the thirst for advanced energy storage materials. As a high capacity anode, however, the application of NiO nanoparticles (NiO NPs) is hindered by intractable issues of dramatic volume change, intrinsic low electronic conductivity, and severe aggregation tendency during lithiation/delithiation. Herein, a polydopamine (PDA) assisted bi‐functionalization strategy for fabricating of PDA@NiO‐CNT composites for fast and durable lithium storage is reported. In this composite, CNTs intertwine to form a network to ensure sufficient electrolyte infiltration and act as a highly conductive system to motivate fast charge transmission. The strong binding affinity of PDA facilitates bonding between NiO NPs and CNTs, which not only forms uniform and flexible PDA coating but also ensures homogeneous distribution of NiO NPs on CNTs network. Therefore, the bi‐functional modified PDA@NiO‐CNT electrode possesses high conductivity, alleviates volume change and aggregation of NiO NPs during cycling, achieves a reversible capacity of 1326 mAh g−1 at 100 mA g−1, a rate capability of 215 mAh g−1 at 2000 mA g−1 and a cycling stability with 78% capacity retention after 250 cycles. This bi‐functional modification approach manifests its prospective potential for architecting other electrode materials toward high‐performance electrochemical devices.
