文摘	锂离子电池是目前电脑、通讯、消费电子品以及未来电动车动力系统的主要能源.硅基负极材料因其具有较高理论比容量(4200 mAh·g~(-1),为石墨10倍以上) ,被视为最理想的下一代锂离子电池负极材料.然而硅负极在充放电过程中巨大的体积膨胀造成极片材料的粉化脱落、SEI膜的持续增长、正极锂离子的不断消耗,以及现有商业化粘结剂与硅表面较弱的相互作用等诸多缺陷,造成电池容量快速的衰减,阻碍了硅基材料在锂离子电池中的商业化应用.本文对硅基负极材料及其相关电池材料,如硅材料结构、粘结剂、电解液及添加剂等,进行了系统全面的总结.最后对硅基材料目前研究进展和未来发展方向做出总结与评述,以期为下一代硅基电池体系发展提供参考.
其他语种文摘	Lithium ion batteries(LIBs) have been widely used as the energy storage system for the applications of the laptop,the communication equipment and the consumer electronics. And importantly,it will be largely used in the electrical vehicles in the near future. Silicon with a high theoretical capacity of 4200 mAh·g~(-1)(more than 10 time of current graphite anode) is one of the most promising alternative anode material for the next generation of LIBs. However,the electrode pulverization,continuous growth of solid electrolyte interphase(SEI) and lithium consumption in silicon anode material based batteries usually happen during charge /discharge process due to its huge volume change. Moreover,the weak interaction between conventional binder and silicon anode material results in the continuous separation of silicon active material. These problems severely hinder the practical application of silicon anode material. This review systematically summarize the recent progress of silicon and its related materials for LIBs. The content includes the fabrication of silicon materials,the structure of silicon materials,binders,electrolytes and electrolyte additives. Finally,the future development direction of siliconbased materials is presented.
