Recently, the growing demand for high-performing batteries and different environmental challenges (such include global warming and climate change) have increased the requirement and demand for Lithium-ion batteries (LIBs) used in advanced technologies (i.e., electric cars and many others). To meet this increasing demand, there is an urgent need for more advanced technologies and materials. In the pursuit of developing anode materials, silicon has emerged as the utmost favourable choice for the next generation of LIBs, aiming to substitute the commonly used graphite. Carbon is commonly used to render silicon (Si) suitable for use since Si cannot be used directly as the electrode in LIBs. One of the recently discovered techniques in the development of high-performance LIBs is the use of inexpensive, sustainable, renewable, and eco-friendly materials. Agro-waste-derived silicon and carbon are often used as long as they don't negatively affect the LIB anode's performance. This review paper presents the advances in the development of silicon-carbon (Si/C) composite anodes sourced from agro-waste for applications in LIBs. It provides an overview of agro-waste-derived silicon-based anode materials and techniques for extracting silica from agricultural wastes. Next, the outline explains the preparation technique of Si/C composites obtained from agricultural residues for use in LIBs. Additionally, the paper delves into recent research challenges and the potential prospects of materials derived from agro-waste in the advancement of sophisticated LIBs battery materials.
最近，对高性能电池不断增长的需求以及各种环境挑战（包括全球变暖和气候变化），增加了对先进技术（如电动汽车等）中使用的锂离子电池（LIBs）的要求和需求。为了满足这一不断增长的需求，迫切需要更先进的技术和材料。在开发负极材料的过程中，硅已成为下一代LIBs最有利的选择，旨在替代常用的石墨。由于硅不能直接用作LIBs的电极，通常使用碳来使硅适合使用。开发高性能LIBs的最新技术之一是使用廉价、可持续、可再生和环保的材料。只要农业废弃物衍生的硅和碳不会对LIB负极的性能产生负面影响，它们就经常被使用。这篇综述文章介绍了用于LIBs的农业废弃物来源的硅碳（Si/C）复合负极的开发进展。它概述了农业废弃物衍生的硅基负极材料以及从农业废弃物中提取二氧化硅的技术。接下来，该概述解释了从农业残留物中获得用于LIBs的Si/C复合材料的制备技术。此外，本文深入探讨了近期的研究挑战以及农业废弃物衍生材料在先进LIBs电池材料发展中的潜在前景。
