Developing novel supercapacitor electrodes with high energy density and good cycle stability has aroused great interest. Herein, the vertically aligned CoNiO2/Co3O4 nanosheet arrays anchored on boron doped diamond (BDD) films are designed and fabricated by a simple one-step electrodeposition method. The CoNiO2/Co3O4/BDD electrode possesses a large specific capacitance (214 mF cm−2) and a long-term capacitance retention (85.9% after 10,000 cycles), which is attributed to the unique two-dimensional nanosheet architecture, high conductivity of CoNiO2/Co3O4 and the wide potential window of diamond. Nanosheet materials with an ultrathin thickness can decrease the diffusion length of ions, increase the contact area with electrolyte, as well as improve active material utilization, which leads to an enhanced electrochemical performance. Additionally, CoNiO2/Co3O4/BDD is fabricated as the positive electrode with activated carbon as the negative electrode, this assembled asymmetric supercapacitor exhibits an energy density of 7.5 W h kg−1 at a power density of 330.5 W kg−1 and capacity retention rate of 97.4% after 10,000 cycles in 6 M KOH. This work would provide insights into the design of advanced electrode materials for high-performance supercapacitors.

“…However, despite their structural simplicity, organic polymers are typically more expensive and difficult to control processes with as a carbon source. While biomass does possess certain beneficial attributes, including cost‐effectiveness and environmental sustainability, it typically demonstrates a comparatively slower rate of carbonization [9–12] . Mesophase pitch (MP) consists of a combination of diverse pancake‐shaped polycyclic aromatic hydrocarbons and can be prepared by condensation reaction of heavy oils such as petroleum pitch, coal tar oil, and aromatic compounds [13,14] .…”

Hierarchical porous carbon (HPC) materials for supercapacitor (SC) application are synthesized via a one‐step carbonization and activation method, using a novel composite activating agent with synergistic activation effect from mesophase pitch (MP) as precursor. The prepared mesophase pitch‐based porous carbon (MPPC) exhibits an ultra‐high specific surface area (SSA) of 2955.0 m2 g−1, well‐controlled pore size distribution (PSD), and exceptional electrochemical performance. The specific capacitance of MPPC‐4 attains up to 338.1 F g−1 at 1 A g−1 and 250.1 F g−1 at 20 A g−1, demonstrating remarkable rate capability. Furthermore, the assembled symmetric SC achieves a high energy density of 29.83 Wh kg−1 at a power density of 999.93 W kg−1 and still maintains 6.56 Wh kg−1 at a high power density of 19.89 kW kg−1. Furthermore, the SC exhibits advantageous cyclic stability, as evidenced by its remarkable capacitance retention rate of 88.55 % even after 5000 cycles. The utilization of this novel composite activating agent in the synthesis of pitch‐derived porous carbon (PC) electrode materials is an exceptionally effective and inventive process.

“…Electrochemical applications such as supercapacitors, fuel cells, batteries, or sensors require carbon electrode materials that meet certain characteristics, such as the absence of impurities, a high electrical conductivity to ensure fast electron transport, high porosity, and a specific surface area and pore size distribution that are suitable for the application [ 1 , 2 , 3 , 4 ]. Specifically, supercapacitors involve carbon electrode materials with high specific surface areas, above 2000 m 2 g −1 [ 5 , 6 , 7 , 8 ], combined with a mesoporous structure (the absence of large pores). In fact, the size, distribution, and geometry of the pores have a great influence on the performance of these devices [ 1 , 9 ].…”

Carbonaceous materials used in most electrochemical applications require high specific surface area, adequate pore size distribution, and high electrical conductivity to ensure good interaction with the electrolyte and fast electron transport. The development of transition metal doped graphene aerogels is a possible solution, since their structure, morphology, and electrical properties can be controlled during the synthesis process. This work aims to synthesize Ni-doped graphene aerogels to study the role of different nickel salts in the sol-gel reaction and their final properties. The characterization data show that, regardless of the nature of the Ni salts, the surface area, volume of micropores, and enveloped density decrease, while the porosity and electrical conductivity increase. However, differences in morphology, mesopore size distribution, degree of order of the carbon structure, and electrical conductivity were observed depending on the type of Ni salt. It was found that nickel nitrate results in a material with a broader mesopore distribution, higher electrical conductivity, and hence, higher electrochemical surface area, demonstrating that graphene aerogels can be easily synthesized with tailored properties to fit the requirements of specific electrochemical applications.
