Silicon has emerged as the next‐generation anode material for high‐capacity lithium‐ion batteries (LIBs). It is currently of scientific and practical interest to encounter increasingly growing demands for high energy/power density electrochemical energy‐storage devices for use in electric vehicles (xEVs), renewable energy sources, and smart grid/utility applications. Improvements to existing conventional LIBs are required to provide higher energy, longer cycle lives. This is attributed to its unparalleled theoretical capacity (4200 mAh g−1 for Li4.4Si), which is approximately 10 times higher than that of a state‐of‐the‐art graphitic anode (372 mAh g−1 for LiC6), with a suitable operating voltage, natural abundance, environmental benignity, nontoxicity, high safety, and so forth. However, despite the overwhelming beneficial features, the practical integration of LIBs containing a silicon anode beyond the commercial niche is hampered by unavoidable challenges, such as excessive volume changes during the (de‐)alloying process, inherently low electrical and ionic conductivities, an unstable solid–electrolyte interphase, and electrolyte drying out. Among various extenuating strategies, non‐electrode factors encompassing electrolyte additives and polymeric binders are regarded as the most economical, and effective approaches towards circumventing these disadvantages are in short supply. With the aim of providing an in‐depth insight into rapidly growing accounts of electrolyte additives and binders for use with silicon anode‐based LIBs, this Review assesses the current state of the art of research and thereby examines opportunities to open up new avenues for the practical realization of these silicon anode‐based LIBs.

“…Such a volume change usually leads to pulverization issue among Si nanomaterials, which is accompanied by their electrical contact loss among Si particles, nally resulting in capacity fading. 3,4 To overcome this limitation, the integration of inactive transition metals into nanostructured Si to form Si-based alloys, [5][6][7][8][9][10][11][12][13][14] nanostructured Si/carbon-based composites (e.g., graphite/nanostructured Si/carbon 15,16 and nanosilicon cluster-SiO x -C 17 ), and nanostructured Si/SiO 2 18 have recently garnered great attention for good, stable cycling performance with high specic capacities. Among these nanostructured Si-based anode materials, we especially focus on the transition metal/Si-based alloy nanocomposite anode structure.…”

Lithium-ion batteries are widely used in various industries, such as portable electronic devices, mobile phones, new energy car batteries, etc., and show great potential for more demanding applications like electric vehicles. Among advanced anode materials applied to lithium-ion batteries, silicon–carbon anodes have been explored extensively due to their high capacity, good operation potential, environmental friendliness and high abundance. Silicon–carbon anodes have demonstrated great potential as an anode material for lithium-ion batteries because they have perfectly improved the problems that existed in silicon anodes, such as the particle pulverization, shedding and failures of electrochemical performance during lithiation and delithiation. However, there are still some problems, such as low first discharge efficiency, poor conductivity and poor cycling performance, which need to be improved. This paper mainly presents some methods for solving the existing problems of silicon–carbon anode materials through different perspectives.
