“…The anode of a Li-ion battery should operate at low potentials and offer high specific energy capacity and density. However, several drastic challenges prevent the practical application of silicon anodes such as its huge (300%) volume change upon full lithiation, which causes the solid electrolyte interface (SEI) rupture or particle pulverization, leading to loss of electrical contact, fast reversible capacity loss, and low coulombic efficiency [ 2 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. In recent years, research interest toward SiO 2 -based materials as a promising new alternative to graphite has been significantly increased due to the high theoretical capacity and low discharge potential similar to pure silicon.…”

Porous silica-based materials are a promising alternative to graphite anodes for Li-ion batteries due to their high theoretical capacity, low discharge potential similar to pure silicon, superior cycling stability compared to silicon, abundance, and environmental friendliness. However, several challenges prevent the practical application of silica anodes, such as low coulombic efficiency and irreversible capacity losses during cycling. The main strategy to tackle the challenges of silica as an anode material has been developed to prepare carbon-coated SiO2 composites by carbonization in argon atmosphere. A facile and eco-friendly method of preparing carbon-coated SiO2 composites using sucrose is reported herein. The carbon-coated SiO2 composites were characterized using X-ray diffraction, X-ray photoelectron spectroscopy, thermogravimetry, transmission and scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy, cyclic voltammetry, and charge–discharge cycling. A C/SiO2-0.085 M calendered electrode displays the best cycling stability, capacity of 714.3 mAh·g−1, and coulombic efficiency as well as the lowest charge transfer resistance over 200 cycles without electrode degradation. The electrochemical performance improvement could be attributed to the positive effect of the carbon thin layer that can effectively diminish interfacial impedance.

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.

Si‐based anodes have large intrinsic volume expansion, which hinders their practicality and commercialisation. To address this challenge, the design principle of intrinsic zero‐strain anodes (① large intracrystalline cavities and ② strong bonds) is proposed, and silica with large intracrystalline cavities (SLIC) established by strong Si–O bonds ([SiO4] coordinate structures) is obtained and acts as an anode, achieving the intrinsic zero‐strain feature first in silicon‐based anodes. The phase structure of SLIC is maintained and the [SiO4] coordinate structure merely shows slight disorder during cycling. The feature stems from lithiation taking place by the solid‐solution insertion reaction rather than the conventional conversion/alloying addition reactions, because the solid‐solution insertion reaction for the SLIC has the lowest change in the Gibbs free energy. The SLIC anode demonstrates excellent cycling stability and high initial Coulombic efficiency (∼85%). Moreover, owing to the low working voltage (∼0.28 V) and relatively high specific capacity, the SLIC anode presents the highest gravimetric energy density among reported zero‐/quasi‐zero‐strain anodes and high volumetric energy density (around twice as much as graphite). The universality of the designing principle is also validated. Our work provides design guidelines for zero‐strain anodes in next‐generation batteries.This article is protected by copyright.
