Lithium batteries (LIBs) with low capacity graphite anode (~ 372 mAh g⁻¹) cannot meet the ever-growing demand for new energy electric vehicles and renewable energy storage. It is essential to replace graphite anode with higher capacity anode materials for high-energy density LIBs. Silicon (Si) is well known to be a possible alternative for graphite anode due to its highest capacity (~ 4200 mAh g⁻¹). Unfortunately, large volume change during lithiation and delithiation has prevented the Si anode from being commercialized. Metal silicides are a promising type of anode materials which can improve cycling stability via the accommodation of volume change by dispersing Si in the metal inactive/active matrix, while maintain greater capacity than graphite. Here, we present a classification of Si alloying with metals in periodic table of elements, review the available literature on metal silicide anodes to outline the progress in improving and understanding the electrochemical performance of various metal silicides, analyze the challenges that remain in using metal silicides, and offer perspectives regarding their future research and development as anode materials for commercial LIBs application.

具有低容量石墨阳极（〜372 mAh g ^-1）的锂电池（LIB）无法满足对新能源电动汽车和可再生能源存储的不断增长的需求。对于高能量密度的LIB，必须用更高容量的阳极材料代替石墨阳极。众所周知，硅（Si）具有最高的容量（〜4200 mAh g ^-1），可以替代石墨阳极）。不幸的是，在锂化和去锂化期间的大体积变化阻止了硅阳极的商业化。金属硅化物是一种有前途的阳极材料，可以通过将硅分散在金属惰性/活性基体中，同时通过保持体积变化来改善循环稳定性，同时保持比石墨更大的容量。在这里，我们介绍了元素周期表中与金属合金化的硅的分类，回顾了有关金属硅化物阳极的现有文献，概述了改善和了解各种金属硅化物的电化学性能的进展，分析了使用金属硅化物时仍然存在的挑战，并就其作为商用LIB应用阳极材料的未来研究和发展提供了观点。
