However, achieving fast charging using a simple and inexpensive strategy without sacrificing its initial Coulombic efficiency remains a challenge in sodium ion batteries. A simple liquid-phase coating approach has been used to generate a pitch-derived soft carbon layer on the HC surface, and its effect on the porosity of HC and SEI chemistry has been studied. A variety of structural characterizations show a soft carbon coating can increase the defect and ultra-micropore contents. The increase in ultra-micropore comes from both the soft carbon coatings and the larger pores within the HC that are partially filled by pitch, which provides more Na+ storage sites. In-situ FTIR/EIS and ex-situ XPS showed that the soft carbon coating induced the formation of thinner SEI that is richer in NaF from the electrolyte, which stabilized the interface and promoted the charge transfer process. As a result, the anode produced fastcharging (329.8 mAh g–1 at 30 mA g–1 and 198.6 mAh g–1 at 300 mA g–1) and had a better cycling performance (a high capacity retention of 81.4% after 100 cycles at 150 mA g–1). This work reveals the critical role of coating layer in changing the pore structure, SEI chemistry and diffusion kinetics of hard carbon, which enables rational design of sodium-ion battery anode with enhanced fast charging capability.\u0000\t\t\t\t<figure><img><ol><li>Download: Download high-res image (121KB)</li><li>Download: Download full-size image</li></ol></figure></div></div>","PeriodicalId":19719,"journal":{"name":"New Carbon Materials","volume":"40 3","pages":"Pages 651-665"},"PeriodicalIF":5.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144501882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They can solve the limitations of two-dimensional (2D) graphene sheets, including interlayer restacking, high contact resistance, and insufficient pore accessibility. By constructing interconnected porous networks, 3D graphenes not only retain the intrinsic advantages of 2D graphene sheets, such as high specific surface area, excellent electrical and thermal conductivities, good mechanical properties, and outstanding chemical stability, but also enable efficient mass transport of external fluid species. We summarize the fabrication methods for 3D graphenes, with a particular focus on their applications in energy-related systems. Techniques including chemical reduction assembly, chemical vapor deposition, 3D printing, chemical blowing, and zinc-tiered pyrolysis have been developed to change their pore structure and elemental composition, and ways in which they can be integrated with functional components. In terms of energy conversion and storage, they have found broad use in buffering mechanical impacts, suppressing noise, photothermal conversion, electromagnetic shielding and absorption. They have also been used in electrochemical energy systems such as supercapacitors, secondary batteries, and electrocatalysis.

The pyrolysis method affects the microstructure of the material, and ultimately its sodium storage performance. Our previous work has shown that pyrolysis in a sealed graphite vessel improved the sodium storage performance of the carbon, however the changes in its microstructure and the way this influences the sodium storage are still unclear. A series of hard carbon materials derived from corncobs (CCG-T, where T is the pyrolysis temperature) were pyrolyzed in a sealed graphite vessel at different temperatures. As the pyrolysis temperature increased from 1000 to 1400 °C small carbon domains gradually transformed into long and curved domains. At the same time, a greater number of large open pores with uniform apertures, as well as more closed pores, were formed. With the further increase of pyrolysis temperature to 1600 °C, the long and curved domains became longer and straighter, and some closed pores gradually became open. CCG-1400, with abundant closed pores, had a superior SIB performance, with an initial reversible capacity of 320.73 mAh g−1 at a current density of 30 mA g−1, an initial Coulomb efficiency (ICE) of 84.34%, and a capacity retention of 96.70% after 100 cycles.
