Lithium-ion batteries (LIBs) play an important role in modern society. The low capacity of graphite cannot meet the demands of LIBs calling for high power and energy densities. Silicon (Si) is one of the most promising materials instead of graphite, because of its high theoretical capacity, low discharge voltage, low cost, etc. However, Si shows low conductivity of both ions and electrons and exhibits a severe volume change during cycles. Fabricating nano-sized Si and Si-based composites is an effective method to enhance the electrochemical performance of LIB anodes. Using a small size of Si nanoparticles (SiNPs) is likely to avoid the cracking of this material. One critical issue is to disclose different types and electrochemical effects of various coupled materials in the Si-based composites for anode fabrication and optimization. Hence, this paper reviews diverse SiNP-based composites for advanced LIBs from the perspective of composition and electrochemical effects. Almost all kinds of materials that have been coupled with SiNPs for LIB applications are summarized, along with their electrochemical influences on the composites. The integrated materials, including carbon materials, metals, metal oxides, polymers, Si-based materials, transition metal nitrides, carbides, dichalcogenides, alloys, and metal–organic frameworks (MOFs), are comprehensively presented.

用于高级锂离子电池阳极的硅纳米颗粒基复合材料

锂离子电池（LIB）在现代社会中起着重要作用。石墨的低容量无法满足要求高功率和能量密度的LIB的要求。硅（Si）由于其理论容量高，放电电压低，成本低等优点，是代替石墨的最有前途的材料之一。然而，Si显示出离子和电子两者的低电导率，并且在循环期间显示出严重的体积变化。制备纳米尺寸的Si和Si基复合材料是增强LIB阳极电化学性能的有效方法。使用小尺寸的Si纳米颗粒（SiNPs）可能会避免这种材料的破裂。一个关键问题是公开用于阳极制造和优化的硅基复合材料中各种偶联材料的不同类型和电化学效应。因此，本文从组成和电化学效应的角度综述了用于高级LIB的多种基于SiNP的复合材料。归纳了几乎所有与LiNP结合使用SiNPs的材料，以及它们对复合材料的电化学影响。综合材料
