摘要: 锡基负极材料由于具有很高的储锂容量,较低的电压平台和较大的压实密度而得到广泛的研究,是最具应用潜力的下一代锂离子电池负极材料之一.然而,锡基负极材料在充放电过程中巨大的体积效应导致电极材料破碎粉化脱落,严重降低了电池的循环寿命和限制了其商业化应用.超细化和复合化是解决锡金负极材料缺陷的有效途径,本文论述了近年来在锡基负极材料研究方面的热点及最新成果,特别是超细SnO2纳米颗粒及其与碳纳米管或石墨烯复合负极材料方面的研究进展.

Abstract: As one of the promising anode materials for next-generation lithium ion batteries, tin-based materials have received considerable attentions owing to their high lithium storage capacity,lower voltage plateau and large compacted density. However,the large volume change during the charge/discharge process always results in severe pulverization problems,which greatly limits the life time and thus their commercial applications. Size-minimizing and hybridizing are two effective approaches to solve this problem of tin-based alloying anodes. In this paper,we reviewed the latest research progress and hot topics on the tin-based anode materials, especially the ultra-small SnO2 nanoparticles and their hybridizing with carbon nanotubes and/or graphenes.

Key words: lithium ion batteries, tin-based, anode, size-minimizing, hybridizing
