“…The combination of versatile properties makes hard carbons ideal anode materials not only in LIBs but also in their promising applications such as SIBs and PIBs. [ 89–95 ] Previous reports have proved some significant differences in the intercalated behaviors of Li + , Na + , and K + ions in graphite. To better understand the mechanism of Li + ions storage in hard carbons, the electrochemical behaviors of Na + and K + ions in hard carbons have been collectively compared.…”

Carbonaceous materials have been accepted as a promising family of anode materials for lithium‐ion batteries (LIBs) owing to optimal overall performance. Among various emerging carbonaceous anode materials, hard carbons have recently gained significant attention for high‐energy LIBs. The most attractive features of hard carbons are the enriched microcrystalline structure, which not only benefits the uptake of more Li+ ions but also facilitates the Li+ ions intercalation and deintercalation. However, the booming application of hard carbons is significantly slowed by the low initial Coulombic efficiency, large initial irreversible capacity, and voltage hysteresis. Many efforts have been devoted to address these challenges toward practical applications. This paper focuses on an up‐to‐date overview of hard carbons, with an emphasis on the lithium storage fundamentals and material classification of hard carbons as well as present challenges and potential solutions. The future prospects and perspectives on hard carbons to enable practical application in next‐generation batteries are also highlighted.

“…24,31 Indeed, biomassderived carbon materials are very impressive electrode candidates for energy-related applications. Our group also found some unique natural biomass had typical superiorities in designing hard carbon materials, such as sugarcane waste, 32 lotus seedpod, 33 tamarind fruits, 34 and chitosan, 35 but they were still powdered form. Hu's group further broadened wood-based carbon into FTC electrodes for various electrochemical energy storage applications, such as lithium-ion batteries 36 and sodium-ion batteries.…”

The advancement of supercapacitors (SCs) is closely bound up with the breakthrough of rational design of energy materials. Freestanding and thick carbon (FTC) materials with well-organized porous structure is promising SC electrode delivering high areal capacitive performance. However, controllable and sustainable fabrication of such FTC electrode is still of great challenges. Inspired by natural honeycombs with cross-linked multichannel structure, herein, an innovative molecular-cooperative-interaction strategy is elaborately provided to realize honeycomb-like FTC electrodes. The nitrogen-doped porous carbon monolith (N-PCM) is obtained with advantages of interconnect pore structure and abundant nitrogen doping. Such strategy is based on naturally abundant molecular precursors, and free of pore-templates, expensive polymerization catalyst, and dangerous reaction solvent, rendering it a sustainable and cost-effective process. Systematic control experiments reveal that strong interactions among molecular precursors promise the structural stability of N-PCM during carbonization, and rational selection of molecular precursors with chemical blowing features is key step for well-developed honeycomb-like pore structure. Interestingly, the optimized sample exhibits hierarchical pore structure with specific surface area of 626.4 m 2 g À1 and rational N-doping of 7.01 wt%. The derived SC electrode with high mass loading of 40.1 mg cm À2 shows an excellent areal capacitance of 3621 mF cm À2 at 1 mA cm À2 and good rate performance with 2920 mF cm À2 at 25 mA cm À2 . Moreover, the constructed aqueous symmetric SC and quasi-solid-state SC produce high energy densities of 0.32 and 0.27 mWh cm À2 , respectively. We believe that such a composition/microstructure controllable method can promote the fabrication and development of other thick electrodes for energy storage devices.

“…[22] Another appealing feature of hard carbons is their low-cost due to their widely available precursors such as renewable biomass materials, synthesis resin, carbohydrate, and various industrial and agricultural wastes. [23] The synthesis of hard carbons by precursors direct pyrolysis is relatively simple and large-scale manageable. [24] Here, the hard carbons pyrolyzed from different precursors show considerable differences both in structure and electrochemical performances.…”

Carbon materials have attracted extensive attention as anodes for sodium-ion batteries (SIBs) because of the abundant resources, low cost, and diverse structure. Due to the different structure configurations, hard carbons, soft carbons, as well as nanocarbons present distinct electrochemical Na-storage behaviors and properties. The diverse structural and chemical characteristics of carbon materials' precursors have paved pathways to construct a robust carbonbased heterostructure with enhanced electrochemical performances. This review comprehensively discusses the fabrication of carbon-based heterostructures, including hard-hard, hard-soft, and hard-nano heterostructures, with a focus on the formation processes and the benefits of these heterostructures in Na-ion storage. Furthermore, the key obstacles and potential production of such heterostructures are explored, disclosing future structural design of highperformance carbon-based anode materials for SIBs.
