“…To overcome the limitation mentioned above, constructing the active material with ordered nanoarray structure (such as one-dimensional (1D) nanorods [15], two-dimensional (2D) nanosheets [16], and three-dimensional (3D) flower-like [17]) on the N-doped hierarchical porous carbonaceous backbones omits the cumbersome electrode preparation process, which simultaneously guarantees approachability to electrolyte ions, supplies sufficient channels for ion transport, increases the exposure of redox-active sites, and avoids agglomeration to tackle the aforementioned deficiencies existing in NiCo2Se4 [18,19]. According to previous reports, 2D and 3D nanostructures are favored for their unique physical, electronic, and chemical properties.…”

Developing suitable electrode materials for electrochemical energy storage devices by biomorph assisted design has become a fascinating topic due to the fantastic properties derived from bio-architectures. Herein, zephyranthes-like Co 2 NiSe 4 arrays grown on butterfly wings derived three-dimensional (3D) carbon framework (Z-Co 2 NiSe 4 /BWC) is fabricated via hydrothermal assembly and further conversion method. Benefiting from its unique structure and multi-components, the obtained Z-Co 2 NiSe 4 /BWC electrode for supercapacitor delivers an excellent specific capacitance of 2,280 F•g −1 at 1 A•g −1 . Impressively, the constructed asymmetric supercapacitor using Co 2 NiSe 4 /BWC as positive electrode and activated butterfly wings carbon as negative electrode acquires a high energy density of 42.9 Wh•kg −1 at a power density of 800 W•kg −1 with robust stability of 94.6% capacitance retention at 10 A•g −1 after 5,000 cycles. Moreover, the Z-Co 2 NiSe 4 /BWC as anode for sodium-ion batteries exhibits a high specific capacity of 568 mAh•g −1 at 0.1 A•g −1 and high cycling stability (maintaining 80.1% of the second cycle after 100 cycles). The outstanding electrochemical performances are ascribed to that the synergistic effect of bimetallic selenides and N-doped carbon improves electrochemical activities and conductivity. One-dimensional (1D) nanoneedles grown on 3D porous framework increase the exposure of redox-active sites, endow adequate transmission channels of electrons/ions, and guarantee stability of the electrode during charge/discharge processes. This study will shed light on the avenue towards extending such nanohybrids to excellent energy storage applications.

“…CC also exhibits good flexibility and plasticity, as observed in the digital photograph of commercial CC, with an area of 1 × 4 cm 2 ( Figure 2 a). As shown in Figure 2 b, Liu et al [ 107 ] synthesized uniform honeycomb-like NiCo 2 S 4 nanosheets grown on CC with an excellent capacitance up to 1638 F·g −1 at 1 A·g −1 . Graphene quantum dots on carbon cloth can somewhat improve specific capacitance over carbon cloth and maintain perfect flexibility, but its performance is far from adequate [ 10 ].…”

Supercapacitors have the unique advantages of high power density, fast charge and discharge rates, long cycle life, high safety, and reliability, and are increasingly being used for applications including automobiles, rail transit, communication equipment, digital electronics, and aerospace equipment. The supercapacitor industry is currently in a stage of rapid development; great breakthroughs have also been made in improving the performance of supercapacitors and the expansion of their application. Electrode technology is the core of supercapacitors. Transition-metal compounds have a relatively high theoretical capacity and have received widespread attention as electrode materials for supercapacitors. In addition, there is a synergistic effect between the different components of various electrode composite materials. Due to their superior electrochemical performance, supercapacitors are receiving increasing research attention. Flexible supercapacitors have been hailed for their good plasticity, resulting in a development boom. This review article mainly outlines the development process of various electrode materials, including carbon materials, conductive polymers, metal compounds, and composite materials, as well as flexible electrode materials based on carbon cloth.

With the development of light-weight and bendable electric devices, nowdays, solid-state supercapacitive devices have attracted great attention, in which the classic polymeric electrolytes such as polyvinyl alcohol and polyethylene oxide copolymers are generally used. However, the microphase separation in these polymers and low conductivity affect the ions transfer and the energy-storage performance. In this work, a crosslinked sodium polyacrylate gel (NaPA) is synthesized to replace conventional polymeric electrolyte. Because NaPA is a kind of polymeric salt which has high native degree of ionization in water, the NaPA gel shows low resistance to ion transportation. By using NaPA gel as the electrolyte and carbon cloth as current collector, a flexible solid asymmetric super-capacitor assembled by positive NaFePO 4 /carbon cloth and negative activated carbon/carbon cloth electrode shows the maximum capacitance of 46.33 mF cm À 2 at 1 mA cm À 2 , with a high stability of 87.33 % retention during 5000 charge and discharge cycles. Moreover, this flexible asymmetric supercapacitors showed nearly unchanged capacitance under different bending angles. It is found that the Na + diffusion coefficient in NaFePO 4 /CC//NaPA supercapacitor is 8.05 × 10 À 14 cm 2 ⋅ s, remarkable higher than CC//NaPA and NaFePO 4 / CC//PVA. The high diffusion coefficient and low resistance of NaPA lead to excellent capacitave performance of NaFePO 4 / CC//NaPA, delivering a good application prospect.
