Abstract

Within the lithium-ion battery sector, silicon (Si)-based anode materials have emerged as a critical driver of progress, notably in advancing energy storage capabilities. The heightened interest in Si-based anode materials can be attributed to their advantageous characteristics, which include a high theoretical specific capacity, a low delithiation potential, wide availability, and cost-effectiveness. However, these materials are not immune to challenges. One prominent issue arises from the significant volume changes that occur during lithiation (charging) and delithiation (discharging) processes, resulting in mechanical stress within the material. This stress leads to structural degradation over time, thereby reducing capacity and performance. Another critical concern revolves around the inherent low electronic conductivity of Si-based materials and their limited cycling stability, which limits their practical application on a commercial scale. This comprehensive review thoroughly examines recent advancements in SiOx (0 < x ≤ 2)-based anode materials, with a specific focus on SiO2 and Si-carbon composites, delving into their electrochemical properties and mechanisms. It also highlights existing challenges and suggests potential avenues for improvement, providing valuable insights for future research directions. The synthesis methods and performance benchmarks discussed in this review are essential for developing more efficient and sustainable SiOx-based anodes across various energy storage applications.

利用硅制造锂离子电池阳极:揭示进展、障碍和前景(综述)
摘要在锂离子电池领域,硅(Si)基负极材料已成为推动技术进步的关键因素,特别是在提高储能能力方面。硅基负极材料之所以备受关注,是因为它们具有理论比容量高、脱ithiation 电位低、可用性广和成本效益高的优势特点。然而,这些材料也面临着挑战。一个突出的问题是,在锂化(充电)和脱锂(放电)过程中会发生显著的体积变化,导致材料内部产生机械应力。随着时间的推移,这种应力会导致结构退化,从而降低容量和性能。另一个关键问题是硅基材料固有的低电子传导性及其有限的循环稳定性,这限制了它们在商业规模上的实际应用。本综述深入探讨了 SiOx(0 < x ≤ 2)基负极材料的最新进展,特别关注 SiO2 和 Si 碳复合材料,深入研究了它们的电化学性能和机理。报告还强调了现有的挑战,并提出了潜在的改进途径,为未来的研究方向提供了宝贵的见解。本综述中讨论的合成方法和性能基准对于在各种储能应用中开发更高效、更可持续的氧化硅基阳极至关重要。
