[62] In this process, single or multiple materials are put into a milling pot and experienced collision from milling balls and particles of each other. Under the action of high temperature and high energy, material particles suffer deformation and fracture, resulting in grain refinement, size decrease, surface modification, and even new chemical reactions.…”

Silicon has been considered as one of the best alternatives to replace widely used graphite anodes for lithium‐ion batteries, owing to its high theoretical capacity, proper working voltage, abundant availability, and environmental friendliness. Nevertheless, there are many obstacles that hamper the practical applications of silicon anode materials such as huge volume change, low electrical and ionic conductivity, and unstable solid electrolyte interface (SEI), which lead to the pulverization of silicon and severe attenuation of capacity. Among numerous solutions, compounding with carbon is a promising and effective one that attracts more and more attention. In silicon/carbon (Si/C) hybrid anodes, Si acts as the active material that provides high capacity and carbon improves the conductivity as well as alleviates the expansion of Si. In this review, research progresses and developments of Si/C anode materials are summarized mainly from the point of structure design and synthesis methods. Issues and possible solutions are also discussed.

“…[16][17][18][19][20] Nanostructuring of silicon has evolved from nanoparticles to complex hierarchical structures. [21][22][23] Commercially available silicon nanoparticles have been investigated because of their high practical capacity owing to the nanoscale diameter for the short electron pathway and compatibility with current electrode manufacturing processes. [16,24] However, during cycling, silicon nanoparticles are susceptible to losing electrical contact, resulting in capacity fade and reduction of battery lifetime.…”

Silicon shows great promise as a high‐capacity anode material for lithium‐ion batteries. Nanostructuring silicon minimizes the impact of fracturing during charging and discharging. However, synthesizing nanostructured silicon typically requires complicated procedures with high manufacturing costs. Additionally, these complicated procedures typically have poor secondary particle formation, a requirement to achieve a high tap density. Here, a cost‐effective synthesis procedure which generates nearly ideal secondary particle clusters of nanostructured silicon is developed. The cost‐effectiveness is a result of the in operando generation of silicon iodide from iodine gas and low‐grade silicon microparticle. Decomposition of silicon iodide into crystalline silicon and iodine gas enables recycling of the iodine gas, allowing for near full reutilization of iodine in the following cycles. The optimal nanostructures and microstructures of silicon synthesized by the recyclable iodide decomposition reaction enables 83.6% capacity retention over 1000 cycles. The good performance is a result of well‐maintained morphology during cycling, enabling reutilization of the solid electrolyte interphase.

“…Besides, the stress caused by volume expansion not only induces fracture to the electrode in multiple cycles, but also leads to cascade effect affecting the safety of battery. For instance, a reduction in internal porosity of the battery reduces the lithium ion (Li + ) moving channel and subsequently causes the precipitation of lithium metal [12] . Finally, when the battery discharges to low potential, the organic electrolyte tends to decompose and deposit on the surface of anode, forming a solid electrolyte interphase (SEI).…”

Silicon‐based materials that have higher theoretical specific capacity than other conventional anodes, such as carbon materials, Li2TiO3 materials and Sn‐based materials, become a hot topic in research of lithium‐ion battery (LIB). However, the low conductivity and large volume expansion of silicon‐based materials hinders the commercialization of silicon‐based materials. Until recent years, these issues are alleviated by the combination of carbon‐based materials. In this review, the preparation of Si/C materials by different synthetic methods in the past decade is reviewed along with their respective advantages and disadvantages. In addition, Si/C materials formed by silicon and different carbon‐based materials is summarized, where the influences of carbons on the electrochemical performance of silicon are emphasized. Lastly, future research direction in the material design and optimization of Si/C materials is proposed to fill the current gap in the development of efficient Si/C anode for LIBs.
