“…Silicon-based materials are considered one high-capacity anode material with great potential for development because of their higher theoretical capacity and lower embedded lithium potential compared with conventional graphite electrodes and abundant natural resources [ 7 , 8 , 9 ]. However, silicon cathode materials also have the following disadvantages: silicon undergoes volume changes during charging and discharging, resulting in stress-strain and leading to cracks or even pulverization of the silicon cathode; the solid electrolyte interface film (SEI) is unstable, and the silicon cathode material after cracking exposes a fresh surface which can form an SEI film again and hinder the migration of Li + [ 10 ]; the structural changes and volume effects of the silicon cathode lead to the cracking of the silicon cathode during repeated lithiation process of silicon cathode material from the electrode structure, resulting in the rapid failure of the battery [ 11 , 12 , 13 ]. To address these problems, current research has focused on both silicon nanosizing [ 14 , 15 ] and designing silicon-based composites to mitigate the bulk expansion of silicon and maintain the stability of SEI films.…”

Silicon-based anode materials are considered one of the highly promising anode materials due to their high theoretical energy density; however, problems such as volume effects and solid electrolyte interface film (SEI) instability limit the practical applications. Herein, silicon nanoparticles (SiNPs) are used as the nucleus and anatase titanium dioxide (TiO2) is used as the buffer layer to form a core-shell structure to adapt to the volume change of the silicon-based material and improve the overall interfacial stability of the electrode. In addition, silver nanowires (AgNWs) doping makes it possible to form a conductive network structure to improve the conductivity of the material. We used the core-shell structure SiNPs@TiO2/AgNWs composite as an anode material for high-efficiency Li-ion batteries. Compared with the pure SiNPs electrode, the SiNPs@TiO2/AgNWs electrode exhibits excellent electrochemical performance with a first discharge specific capacity of 3524.2 mAh·g−1 at a current density of 400 mA·g−1, which provides a new idea for the preparation of silicon-based anode materials for high-performance lithium-ion batteries.

“…Research into nanosized silicon materials such as silicon nanowires, silicon nanorods, and silicon nanoparticles (SINPs), aimed at overcoming the problems associated with the volume expansion of silicon during charging and discharging, is in progress. − According to Liu et al, the generation of silicon particle defects due to volume expansion is suppressed by decreasing hoop tension during the lithiation of silicon nanoparticles with sizes of 150 nm or lesser . Defect mitigation through volume expansion also prevents the regeneration of the solid electrolyte interface (SEI) layer, which in turn improves reversibility as well as cycling performance. , Additionally, nanosized silicon shows excellent rate performance relative to microsized silicon, which is ascribable to shorter diffusion pathways for ions and electrons associated with its high specific surface area . However, as observed for microsized silicon, nanosized silicon requires more than 40 wt % of a conductive material due to its low conductivity, and the formation of a stable SEI layer is difficult due to its direct contact with the electrolyte, both of which are significant disadvantages. , To address this concern, methods for compounding nanosized silicon and carbon materials in composite forms are being studied. − …”

With a 10-fold higher theoretical capacity than that of graphite, silicon has excellent potential for use as an active anode material in lithium-ion (Li-ion) batteries, especially when high capacity and high energy density are required. In this study, we improved the lifetime characteristics of silicon nanoparticles (SINPs) by synthesizing a Si/C composite anode composed of carbonized fibroin (pyroprotein) and SINPs. The pyroprotein matrix effectively accommodates the volume expansion of the SINPs during charging and discharging, thereby suppressing the formation of surface defects on the electrode. This pyroprotein matrix also provides additional storage sites for Li-ion chemisorption and uniformly delivers Li ions to the SINP surfaces through a solid–solution reaction. The Si/C anode exhibits improved rate capability compared to that of the SINPs, with a 30% higher capacity retention over 50 cycles. Furthermore, even in a graphite-silicon (G-Si) composite anode, the G-Si/C anode showed a capacity retention rate of 99.5% over 100 cycles, which is superior to the performance of silicon-based anode materials; hence, it is a potential candidate for use in long-life G-Si composite anodes.

Si-based anode materials offer significant advantages, such as high specific capacity, low voltage platform, environmental friendliness, and abundant resources, making them highly promising candidates to replace graphite anodes in the next generation of high specific energy lithium-ion batteries (LIBs). However, the commercialization of Si-based anodes for LIBs encounters significant barriers due to inherent challenges. These challenges encompass a range of issues, including poor electrical conductivity, substantial volume expansion during the lithiation−delithiation process, severe pulverization of the electrodes, pronounced thickening of the solid electrolyte interphase film, low Coulombic efficiency, and limited cycling performance. Each of these factors leads to the complexity of realizing the full potential of Si-based anodes in commercial LIBs applications. This review provides a comprehensive summary and discussion of recent research on Si-based LIB anodes, focusing on the microscopic morphology of Si and the development of Si-based composite materials. By offering a novel perspective, this review aims to provide an overview and insightful discussion of Sibased anodes. The latest research findings are presented, and innovative viewpoints and reasonable insights are addressed, shedding light on the potential solutions to overcome the limitations associated with Si-based anodes.
