Silicon (Si) has been considered as the most promising anode material for next generation lithium-ion batteries (LIBs) due to its ultrahigh theoretical specific capacity (4,200 mAh g–1) and volume capacity (9,786 mAh cm–3), relatively low operating voltage (∼0.5 V vs Li+/Li), the abundant natural Si source, and environmental benignity. However, the huge volume expansion and poor conductivity limit seriously the electrochemical reversibility and cycling stability of silicon-based anode materials, and thus hinder their commercial application. To address these issues, herein we put forward a strategy to prepare the spherical graphite/silicon/graphene oxides/carbon (Gr/Si/GO/C) composite by electrostatic self-assembly and spray drying process. The structure and morphology of the as-prepared samples are characterized by X-ray diffraction (XRD), Raman spectrum, Fourier transform infrared spectroscope (FTIR), scanning electron microscope (SEM), electron backscatter diffractometer (EBSD), and transmission electron microscope (TEM). The results show that the as-synthesized Gr/Si/GO/C composite has a high discharge capacity of 1212.0 mAh g–1 at 200 mA g–1 with the initial Coulombic efficiency (ICE) of 80.4%, and the capacity retention rate is 81.7% after 100 cycles. Apparently, the as-prepared spherical Gr/Si/GO/C composite can well buffer the volume expansion of silicon, maintain the structural integrity of the electrode, enhance stability by reducing silicon aggregation, and promote the electric and ionic conductivity as well Li storage ability. Therefore, this strategy of reasonable structure design provides a beneficial exploration for the large-scale industrial application of silicon-based anode materials.

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.

Tin oxide (SnO2) and tin-based composites along with carbon have attracted significant interest as negative electrodes for lithium-ion batteries (LIBs). However, tin-based composite electrodes have some critical drawbacks, such as high volume expansion, low capacity at high current density due to low ionic conductivity, and poor cycle stability. Moreover, complex preparation methods and high-cost carbon coating procedures are considered main challenges in the commercialization of tin-based electrodes for LIBs. In this study, we prepared a Sn/SnO2/C nano-composite structure by employing a low-cost hydrothermal method, where Sn nanoparticles were oxidized in glucose and carboxymethyl cellulose CMC was introduced into the solution. Scanning electron microscope (SEM) and transmission electron microscope revealed the irregular structure of Sn nanoparticles and SnO2 phases in the conductive carbon matrix. The as-prepared Sn/SnO2/C nano-composite showed high first-cycle reversible discharge capacity (2248 mAhg−1) at 100 mAg−1 with a first coulombic efficiency of 70%, and also displayed 474.64 mAhg−1 at the relatively high current density of about 500 mAg−1 after 100 cycles. A low-cost Sn/SnO2/C nano-composite with significant electrochemical performance could be the next generation of high-performance negative electrodes for LIBs.
