Silicon anodes are promising for use in lithium-ion batteries. However, their practical application is severely limited by their large volume expansion leading to irreversible material fracture and electrical disconnects. This study proposes a new top-down strategy for preparing microsize porous silicon and introduces polyacrylonitrile (PAN) for a nitrogen-doped carbon coating, which is designed to maintain the internal pore volume and lower the expansion of the anode during lithiation and delithiation. We then explore the effect of temperature on the evolution of the structure of PAN and the electrochemical behavior of the composite electrode. After treatment at 400 -, the PAN coating retains a high nitrogen content of 11.35%, confirming the presence of C―N and C―O bonds that improve the ionic-electronic transport properties. This treatment not only results in a more intact carbon layer structure, but also introduces carbon defects, and produces a material that has remarkable stable cycling even at high rates. When cycled at 4 A g−1, the anode had a specific capacity of 857.6 mAh g−1 even after 200 cycles, demonstrating great potential for high-capacity energy storage applications.
硅阳极有望用于锂离子电池。然而，由于其体积膨胀较大，导致材料不可逆转地断裂和电气断开，其实际应用受到严重限制。本研究提出了一种自上而下制备微孔硅的新策略，并引入聚丙烯腈（PAN）作为掺氮碳涂层，旨在保持内部孔隙体积，降低阳极在锂化和脱锂过程中的膨胀。然后，我们探讨了温度对 PAN 结构演变和复合电极电化学行为的影响。在 400 - 温度下处理后，PAN 涂层的含氮量高达 11.35%，证实了 C-N 和 C-O 键的存在，从而改善了离子电子传输特性。这种处理方法不仅使碳层结构更加完整，而且还引入了碳缺陷，并产生了一种即使在高速率下也能显著稳定循环的材料。当以 4 A g-1 的速率循环时，该阳极在循环 200 次后仍具有 857.6 mAh g-1 的比容量，显示了其在高容量储能应用方面的巨大潜力。

Hard carbons (HCs) are recognized as potential anode materials for sodium-ion batteries (SIBs) because of their low cost, environmental friendliness, and the abundance of their precursors. The presence of graphitic domains, numerous pores, and disordered carbon layers in HCs plays a significant role in determining their sodium storage ability, but these structural features depend on the precursor used. The influence of functional groups, including heteroatoms and oxygen-containing groups, and the microstructure of the precursor on the physical and electrochemical properties of the HC produced are evaluated, and the effects of carbonization conditions (carbonization temperature, heating rate and atmosphere) are also discussed.

As by-products of petroleum refining, heavy oils are characterized by a high carbon content, low cost and great variability, making them competitive precursors for the anodes of potassium ion batteries (PIBs). However, the relationship between heavy oil composition and potassium storage performance remains unclear. Using heavy oils containing distinct chemical groups as the carbon source, namely fluid catalytic cracking slurry (FCCS), petroleum asphalt (PA) and deoiled asphalt (DOA), three carbon nanosheets (CNS) were prepared through a molten salt method, and used as the anodes for PIBs. The composition of the heavy oil determines the lamellar thicknesses, sp3-C/sp2-C ratio and defect concentration, thereby affecting the potassium storage performance. The high content of aromatic hydrocarbons and moderate amount of heavy component moieties in FCCS produce carbon nanosheets (CNS-FCCS) that have a smaller layer thickness, larger interlayer spacing (0.372 nm), and increased number of folds than in CNS derived from the other three precursors. These features give it faster charge/ion transfer, more potassium storage sites and better reaction kinetics. CNS-FCCS has a remarkable K+ storage capacity (248.7 mAh g−1 after 100 cycles at 0.1 A g−1), long cycle lifespan (190.8 mAh g−1 after 800 cycles at 1.0 A g−1) and excellent rate capability, ranking it among the best materials for this application. This work sheds light on the influence of heavy oil composition on carbon structure and electrochemical performance, and provides guidance for the design and development of advanced heavy oil-derived carbon electrodes for PIBs.
作为石油提炼的副产品，重油具有含碳量高、成本低和可变性大的特点，使其成为钾离子电池（PIB）阳极的有竞争力的前体。然而，重油成分与钾储存性能之间的关系仍不明确。利用含有不同化学组的重油作为碳源，即流体催化裂化浆料（FCCS）、石油沥青（PA）和脱油沥青（DOA），通过熔盐法制备了三种碳纳米片（CNS），并将其用作钾离子电池的阳极。重油的成分决定了薄片厚度、sp3-C/sp2-C 比率和缺陷浓度，从而影响了钾的储存性能。FCCS 中芳香烃含量高，重组分分子含量适中，因此生成的碳纳米片（CNS-FCCS）与其他三种前驱体生成的 CNS 相比，层厚度更小，层间距更大（0.372 nm），褶皱数量更多。这些特点使其具有更快的电荷/离子传输速度、更多的钾储存位点和更好的反应动力学性能。CNS-FCCS 具有出色的 K+ 储存能力（在 0.1 A g-1 条件下循环 100 次后为 248.7 mAh g-1）、较长的循环寿命（在 1.0 A g-1 条件下循环 800 次后为 190.8 mAh g-1）和卓越的速率能力，是该应用领域的最佳材料之一。这项研究揭示了重油成分对碳结构和电化学性能的影响，为设计和开发用于 PIB 的先进重油衍生碳电极提供了指导。

In the development of rechargeable lithium ion batteries (LIBs), silicon anodes have attracted much attention because of their extremely high theoretical capacity, relatively low Li-insertion voltage and the availability of silicon resources. However, their large volume expansion and fragile solid electrolyte interface (SEI) film hinder their commercial application. To solve these problems, Si has been combined with various carbon materials to increase their structural stability and improve their interface properties. The use of different carbon materials, such as amorphous carbon and graphite, as three-dimensional (3D) protective anode coatings that help buffer mechanical strain and isolate the electrolyte is detailed, and novel methods for applying the coatings are outlined. However, carbon materials used as a protective layer still have some disadvantages, necessitating their modification. Recent developments have focused on modifying the protective carbon shells, and substitutes for the carbon have been suggested.

Zinc-ion capacitors (ZICs), which consist of a capacitor-type electrode and a battery-type electrode, not only possess the high power density of supercapacitors and the high energy density of batteries, but also have other advantages such as abundant resources, high safety and environmental friendliness. However, they still face problems such as insufficient specific capacitance, a short cycling life, and narrow operating voltage and temperature ranges, which are hindering their practical use. We provide a comprehensive overview of the fundamental theory of carbon-based ZICs and summarize recent research progress from three perspectives: the carbon cathode, electrolyte and zinc anode. The influence of the structure and surface chemical properties of the carbon materials on the capacitive performance of ZICs is considered together with theoretical guidance for advancing their development and practical use.

Lithium-ion batteries (LIBs) are used in electric vehicles and portable smart devices, but lithium resources are dwindling and there is an increasing demand which has to be catered for. Sodium ion batteries (SIBs), which are less costly, are a promising replacement for LIBs because of the abundant natural reserves of sodium. The anode of a SIB is a necessary component of the battery but is less understood than the cathode. This review outlines the development of various types of anodes, including carbon-based, metallic and organic, which operate using different reaction mechanisms such as intercalation, alloying and conversion, and considers their challenges and prospects. Strategies for modifying their structures by doping and coating, and also modifying the solid electrolyte interface are discussed. In addition, this review also discusses the challenges encountered by the anode of SIBs and the solutions.

There is an urgent need for lithium-ion capacitors (LICs) that have both high energy and high power densities to meet the continuously growing energy storage demands. LICs effectively balance the high energy density of traditional rechargeable batteries with the superior power density and long life of supercapacitors (SCs). Nevertheless, the development of LICs is still hampered by limited kinetic processes and capacity mismatch between the cathode and anode. Metal-organic frameworks (MOFs) and their derivatives have received significant attention because of their extensive specific surface area, different pore structures and topologies, and customizable functional sites, making them compelling candidate materials for achieving high-performance LICs. MOF-derived carbons, known for their exceptional electronic conductivity and large surface area, provide improved charge storage and rapid ion transport. MOF-derived transition metal oxides contribute to high specific capacities and improved electrochemical stability. Additionally, MOF-derived metal compounds/carbons provide combined effects that increase both the capacitive and Faradaic reactions, leading to a superior overall performance. The review begins with an overview of the fundamental principles of LICs, followed by an exploration of synthesis strategies and ligand selection for MOF-based composite materials. It then analyzes the advantages of original MOFs and their derived materials, such as carbon materials and metal compounds, in enhancing LIC performance. Finally, the review discusses the major challenges faced by MOFs and their derivatives in LIC applications and offers future research directions and recommendations.

The development of advanced aircraft relies on high performance thermal-structural materials, and carbon/carbon composites (C/C) composited with ultrahigh-temperature ceramics are ideal candidates. However, the traditional routes of compositing are either inefficient and expensive or lead to a non-uniform distribution of ceramics in the matrix. Compared with the traditional C/C-ZrC-SiC composites prepared by the reactive melt infiltration of ZrSi2, C/C-ZrB2-ZrC-SiC composites prepared by the vacuum infiltration of ZrB2 combined with reactive melt infiltration have the higher content and more uniform distribution of the introduced ceramic phases. The mass and linear ablation rates of the C/C-ZrB2-ZrC-SiC composites were respectively 68.9% and 29.7% lower than those of C/C-ZrC-SiC composites prepared by reactive melt infiltration. The ablation performance was improved because the volatilization of B2O3, removes some of the heat, and the more uniformly distributed ZrO2, that helps produce a ZrO2-SiO2 continuous protective layer, hinders oxygen infiltration and decreases ablation.
