“…SA contains a large number of hydroxyl and carboxyl functional groups, which can provide additional pseudocapacitance with oxygen self-doping. 13 SA-3 exhibited the highest specific capacitance among the four samples because of the largest specific surface area and the appropriate amount of oxygen-containing functional groups. In order to explore the role of oxygen-containing functional groups 54,55 in the charge and discharge process (Fig.…”

“…In order to reach the goal of large-scale application in electric vehicles and power grids, hybrid capacitors should be safe, efficient, and lowcost. 8 Many types of alkali metals 9 have been researched for energy storage, such as lithium, 10,11 sodium 12 and potassium, 13,14 for ion capacitors. They hold decent performance and good prospects but have some shortages [15][16][17] limiting the deep development of these.…”

“…Li and his coworkers used pine needles and graphene oxide as precursors to create hierarchical and porous carbon/graphene networks composed of oxygen (OAC/G). [37] The graphene oxide content in the precursor has a significant effect on the morphology and structure of the derived carbon matrix composites. The in-situ oxygen doping of carbon composites widens the carbon interlayer spacing and increases the active sites on the surface of carbon composites.…”

Potassium‐ion hybrid capacitors (PIHCs) overcome the limitations of potassium‐ion batteries (PIBs) and supercapacitors (SCs) and integrate the advantages of both, including high energy density, high power density, low cost, long cycle life, and stable electrochemical performance. However, the development of PIHCs is hindered by thermodynamic instability and kinetic hysteresis. Additionally, the dynamic mismatch between anode and cathode materials poses an urgent challenge. To this end, many research works related to material development have been dedicated to overcoming the drawbacks. In this review, the energy storage mechanism of PIHCs is briefly introduced. Moreover, the research progress and achievements of anode and cathode materials in recent years are reviewed, including carbon‐based materials, MXenes, transition metal materials, Prussian blue and its analogues. Finally, the challenges and prospects of PIHCs are proposed, together with guiding significant research directions in the future.

Herein, we report the functionalization of carbon nano-onions (CNOs) with the hydroxyaryl group and subsequent modifications with resins: resorcinol–formaldehyde using porogenic Pluronic F-127, resorcinol–formaldehyde-melamine, benzoxazine made of bisphenol A and triethylenetetramine, and calix[4]resorcinarene-derived using F-127. Following the direct carbonization, extensive physicochemical analysis was carried out, including Fourier transform infrared, Raman and X-ray photoelectron spectroscopy, scanning and transmission electron microscopy, and adsorption–desorption of N2. The addition of CNO to the materials significantly increases the total pore volume (up to 0.932 cm3 g−1 for carbonized resorcinol–formaldehyde resin and CNO (RF-CNO-C) and 1.242 cm3 g−1 for carbonized resorcinol–formaldehyde-melamine resin and CNO (RFM-CNO-C)), with mesopores dominating. However, the synthesized materials have poorly ordered domains with some structural disturbance; the RFM-CNO-C composite shows a more ordered structure with amorphous and semi-crystalline regions. Subsequently, cyclic voltammetry and galvanostatic charge–discharge method studied the electrochemical properties of all materials. The influence of resins' compositions, CNO content, and amount of N atoms in carbonaceous skeleton on the electrochemical performance was studied. In all cases, adding CNO to the material improves its electrochemical properties. The carbon material derived from CNO, resorcinol and melamine (RFM-CNO-C) showed the highest specific capacitance of 160 F g−1 at a current density of 2 A g−1, which is stable after 3000 cycles. The RFM-CNO-C electrode retains approximately 97% of its initial capacitive efficiency. The electrochemical performance of the RFM-CNO-C electrode results from the hierarchical porosity's stability and the presence of nitrogen atoms in the skeleton. This material is an optimal solution for supercapacitor devices.
