摘　　要：从便携式电子产品到新能源储存的应用对锂离子电池提出了更高的能量和功率要求。高容量硅(Si)负极被认为是能够突破商用锂离子电池能量密度瓶颈,大幅度提高锂离子电池比容量和充电率的希望之星。本文中,笔者主要围绕硅基材料的改性研究展开综述,介绍了一些具有代表性的锂离子电池负极硅基材料,重点介绍了硅/碳复合材料,并展望了硅基材料的未来发展方向。The application of portable electronics to new energy storage has put forward higher energy and power requirements for lithium-ion batteries,and high-capacity silicon(Si)anode is considered to be the most promising candidate to break the energy density bottle neck of commercial lithium-ion batteries and significantly increase the specific capacity and rate performance.In this paper,we review the modification of Si-based materials,introduce some representative Si-based materials for lithium-ion batteries,focus on Si/C composites,and look into the future direction of Si-based materials.
