Lithium-ion batteries are promising energy storage devices used in several sectors, such as transportation, electronic devices, energy, and industry. The anode is one of the main components of a lithium-ion battery that plays a vital role in the cycle and electrochemical performance of a lithium-ion battery, depending on the active material. Recently, SiO 2 has garnered attention for use as an anode in lithium-ion batteries. SiO 2 has a high specific capacity, good cycle stability, abundance, and low-cost processing. However, the high expansion and shrinkage of the SiO 2 volume during lithiation/delithiation, low conductivity, and solid electrolyte interphase formation resulted in damage to the electrode structure and caused a decrease in SiO 2 performance as an anode for a lithium-ion battery. The modified properties of SiO 2 and the use of carbon materials as composites of SiO 2 are effective strategies to overcome these problems. This review focuses on analyzing the role of various carbon materials in composite SiO 2 /C to enhance the performance of SiO 2 materials.
