“…Design strategies for advanced materials, such as employing unique nanostructures (nanowire, nanotube, core/shell, yolk shell, nanoporous materials, etc) and forming composites with electrochemically inactive/less active materials, such as carbon, conductive polymer, and so forth, have been applied as academic approaches to significantly improve the cycle life. [8][9][10] Nevertheless, the volumetric energy density of these materials and the areal mass loading on electrodes are generally too low for industrial implementation. The commercial goal of achieving high-performance anodes to replace the existing commercial graphite materials in the near future, involves reaching a specific capacity of 500 mAh/g or higher with a capacity retention of 80% after 500 cycles, while the initial CE and average CE should exceed 90% and 99.8%, respectively ( Figure 1).…”

Increasing the energy density of conventional lithium-ion batteries (LIBs) is important for satisfying the demands of electric vehicles and advanced electronics.Silicon is considered as one of the most-promising anodes to replace the traditional graphite anode for the realization of high-energy LIBs due to its extremely high theoretical capacity, although its severe volume changes during lithiation/delithiation have led to a big challenge for practical application. In contrast, the co-utilization of Si and graphite has been well recognized as one of the preferred strategies for commercialization in the near future. In this review, we focus on different carbonaceous additives, such as carbon nanotubes, reduced graphene oxide, and pyrolyzed carbon derived from precursors such as pitch, sugars, heteroatom polymers, and so forth, which play an important role in constructing micrometersized hierarchical structures of silicon/graphite/carbon (Si/G/C) composites and tailoring the morphology and surface with good structural stability, good adhesion, high electrical conductivity, high tap density, and good interface chemistry to achieve high capacity and long cycling stability simultaneously. We first discuss the importance and challenge of the co-utilization of Si and graphite. Then, we carefully review and compare the improved effects of various types of carbonaceous materials and their associated structures on the electrochemical performance of Si/G/C composites. We also review the diverse synthesis techniques and treatment methods, which are also significant factors for optimizing Si/G/C composites. Finally, we provide a pertinent evaluation of these forms of carbon according to their suitability for commercialization. We also make far-ranging suggestions with regard to the selection of proper carbonaceous materials and the design of Si/G/C composites for further development.

“…In the former synthesis, soft‐templates can be easily removed by heating. Interaction between surfactant molecules and guest species is crucial for the formation of porous structures . Since minor variation of the synthesis condition can significantly affect the coassembly process, the hydrolysis and condensation of guest species and their assembly with the surfactants should be carefully controlled to generate the desired porosity .…”

Increasing global challenges such as climate change, environmental pollution, and energy shortage have stimulated the worldwide explorations into novel and clean materials for their applications in the capture of carbon dioxide, a major greenhouse gas, and toxic pollutants, energy conversion, and storage. In this study, two microstructured carbons, namely N‐doped pillaring layered carbon (NC) and N, S codoped honeycomb carbon (NSC), have been fabricated through a one‐pot pyrolysis process of a mixture containing glucose, sodium bicarbonate, and urea or thiourea. The heteroatom doping is found to induce tailored microstructures featuring highly interconnected pore frameworks, high sp2‐C ratios, and high surface areas. The formation mechanism of the varying pore frameworks is believed to be hydrogen‐bond interactions. NSC displays a similar CO2 adsorption capacity (4.7 mmol g−1 at 0 °C), a better CO2/N2 selectivity, and higher activity in oxygen reduction reaction as compared with NC‐3 (the NC sample with the highest N content of 7.3%). NSC favors an efficient four‐electron reduction pathway and presents better methanol tolerance than Pt/C in alkaline media. The porous carbons also exhibit excellent rate performance as supercapacitors.

“…Subsequently, the 3‐aminophenol/formaldehyde (3‐AF) resin was deposited on the porous AlSi material by the polymerization of 3‐aminophenol and formaldehyde in the presence of ammonia and CTAB. In this process, the surface hydroxyl and a thin silicon oxide layer on the surface of silicon provided the negatively charged interface for interaction with cationic surfactant CTAB and subsequent in situ self‐assembly with polymerized 3‐AF resin . Finally, the 3‐AF resin layer was transformed into carbon through carbonization in Ar atmosphere at 700 °C for 5 h with the heating rate of 5 °C min −1 .…”

Silicon is intensively investigated as one of the most promising lithium-ion battery anode material due to its high theoretical capacity. Here, spherical micro-sized porous AlSi coated by a carbon layer (AlSi@C) are fabricated from low-cost commercial AlSi alloy by delicately controlling an acid etching period, followed by polymerization and carbonization. A small amount of residual Al is beneficial to maintain the spherical morphology and enhance the electrical conductivity of the AlSi anode. Profiting from the porous structure and carbon coating layer, micro-sized porous AlSi@C exhibits a high initial coulombic efficiency of 84.2 %, delivers an initial specific discharge capacity of 1650 mA h g À 1 at a current density of 0.50 A g À 1 , and still retains 824 mA h g À 1 after 300 cycles. This work provides a facile and scalable synthetic strategy for the preparation of porous Sibased anode materials from low-cost AlSi alloy, and it is expected to realize the industrialization of preparation of porous Si-based anode materials.
