“…[52,110] It plays a role in a heat transfer medium, supplying conditions for acceptable solubility and diffusivity for solid-phase reactions. [111] Moreover, molten salts rarely have toxic substances, which can even be recycled after washing, so it is considered a green and sustainable process. [112] Peng et al [113] carbonized a petroleum pitch and melamine mixture in a KCl-CaCl 2 molten salt system and produced a nitrogendoped thin carbon nanosheet (NSCN) with excellent Listorage (848 mAh/g) and K-storage(214 mAh/g) ability.…”

It is significant for saving energy to manufacture superb-property batteries. Carbon is one of the most competitive anode materials in batteries, but it is hard for commercial graphite anodes to meet the increasingly higher energy-storage requirements. Moreover, the price of other better-performing carbon materials (such as graphene) is much higher than graphite, which is not conducive to massive production. Pitch, the cheap by-product in the petroleum and coal industries, has high carbon content and yield, making it possible for commercialization. Developing pitch-based anodes can not only lower raw material costs but also realize the pitch's high value-added utilization. We comprehensively reviewed the latest synthesis strategies of pitch-derived materials and then introduced their application and research progress in lithium, sodium, and potassium ion batteries (LIBs, SIBs, and PIBs). Finally, we summarize and suggest the pitch's development trend for anodes and in other fields.

“…In addition to chemical pretreatments, physical gas activation as well as the combination of physical and chemical methods have also been employed to activate wood-based carbon . The reaction of CO 2 gas and air with carbon under high temperatures during the carbonization process leads to improved pore structures.…”

The emergence and development of thick electrodes provide an efficient way for the high-energy-density supercapacitor design. Wood is a kind of biomass material with porous hierarchical structure, which has the characteristics of a straight channel, uniform pore structure, good mechanical strength, and easy processing. The wood-inspired low-tortuosity and vertically aligned channel architecture are highly suitable for the construction of thick electrochemical supcapacitor electrodes with high energy densities. This review summarizes the design concepts and processing parameters of thick electrode supercapacitors inspired by natural woods, including wood-based pore structural design regulation, electric double layer capacitances (EDLCs)/pseudocapacitance construction, and electrical conductivity optimization. In addition, the optimization strategies for preparing thick electrodes with wood-like structures (e.g., 3D printing, freeze-drying, and aligned-low tortuosity channels) are also discussed in detail. Further, this review presents current challenges and future trends in the design of thick electrodes for supercapacitors with wood-inspired pore structures. As a guideline, the brilliant blueprint optimization will promote sustainable development of wood-inspired structure design for thick electrodes and broaden the application scopes.

“…In particular, chitin and protein waste can produce N-doped porous carbons without adding extra nitrogen precursors. And the hierarchical N-doped porous carbon materials with large specific surface areas exhibit high performance in adsorption 115,[121][122][123][124] and catalytic degradation (e.g., peroxydisulfate activation) 116,120 of environmental pollutants. Moreover, heteroatom-doped hierarchical porous carbon materials show a high potential for energy storage (e.g., supercapacitor).…”
