摘要
介绍了近十年来锂离子电池负极用硅/碳纳米复合材料的主要制备方法,包括热解法、化学气相沉积法、球磨法、水热法以及溶胶凝胶法等,以及硅/碳复合材料的微结构特征及其对复合材料比容量和循环性能的影响。最后,对硅/碳纳米复合材料的研究方向进行了展望。
The main preparation methods for Si/C nanocomposites used for cathode of lithium-ion battery in the last decade were introduced, including pyrolysis, chemical vapor deposition, milling, hydrothermal, gel method and so on. The microstructure characteristics of Si/C composite and their effects on specific capacity and cycling performance of composite were introduced, too. At last, the prospects of study direction of Si/C nanocomposites were showed.
