“…Additionally, the doping of carbon material with other atoms would also have a significant impact on their electronic properties. For example, the doping of N can accelerate the conductivity [58][59][60]. The results confirmed the excellent performance of carbon composites in conducting electricity through the CV method calculation, thus indicating their great potential in electronic fields such as supercapacitors.…”

As one of the most versatile elements, carbon materials occupy the most plentiful allotropies composed of pure or mixed hybridization orbitals of sp1/sp2/sp3. The design and synthesis of new carbon materials may be stimulated based on a deeper understanding of underlying structures and related properties. In this review, the initial early discoveries of carbon materials are examined based on their hybridization of orbitals. According to the type of hybridization, the discovered carbon materials are firstly classified and introduced in detail based on their crystal structures. Secondly, its physical and chemical properties, mainly including mechanical properties, optical properties and electronic properties, are reviewed. Thirdly, the existing methods of predicting carbon structure and synthesizing carbon materials are classified and summarized, and some typical carbon materials predicted or prepared are discussed respectively. Then, the main applications of newly synthesized carbon materials in the last two decades are classified and summarized, and the microstructure is linked with the macro properties and specific applications. Finally, the future research opportunities for carbon materials and their potential applications are prospected from the aspects of the gap between theoretical prediction and preparation, the current research hotspot of carbon materials and the incomplete application of carbon materials. It is the authors' intention for this review paper to serve not only as a valuable reference for research into carbon materials and related composites, but also as a guidance for novel materials design at the atomic level.

“…The derived carbon is amorphous, composed of randomly distributed small graphitized fragments and hierarchical pore structure. [53] It has the advantages of fine hierarchical structure, excellent surface electrochemical activity, and electrical conductivity, and it is environmentally friendly and low-cost. Two types of natural precursor-derived materials were developed by Xu et al [54] The first type is a dense, hard carbon from leftover silkworm feed, specifically mulberry tree stems.…”

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.

“…Although CW-derived carbons have been studied as (electro)catalysts, , electrode materials for a sodium-based energy storage device, and supercapacitors, to the best of our knowledge, all-CW-derived dual-carbon PIHCs have not yet been reported. Furthermore, there are only a limited number of works that have presented the fabrication of dual-carbon PIHCs using biomass as a sole carbon precursor. − …”

The microstructure of hard carbon, including interlayer spacing, the degree of graphitization, and doped heteroatoms, has a significant impact on the K + storage capability of hard carbon anodes in potassium-ion hybrid supercapacitors (PIHCs). However, previously reported microstructural engineering methods typically involve complex, time-consuming, and expensive multistep processes. Herein, we report the simple pyrolysis-guided microstructural engineering of hard carbon materials using costeffective coffee waste (CW) as a recycled single carbon source for the fabrication of PIHC devices. For battery-type anodes, the direct pyrolysis of CW at various temperatures (700, 900, and 1100 °C) is conducted to control the microstructures and K + storage behavior of hard carbon anode materials. Carbon prepared at 700 °C exhibits high specific capacity, large capacitive K + storage contribution, and rapid K + storage kinetics as a result of abundant surface defects and functional groups as well as a wide interlayer spacing. For capacitor-type cathodes, high surface area activated carbon is prepared using an industrially available KOH activation method. The optimized PIHC full cell exhibits a high energy density of 120 Wh kg −1 , a power density of 3378 W kg −1 , and a capacity retention of 83.6% after 3000 cycles at 0.5 A g −1 , comparable to carbon materials synthesized by complex multistep processes. These findings indicate that simple microstructural engineering via pyrolysis is sufficient for fabricating dual-carbon PIHCs with an adequate electrochemical performance.
