【摘要】 随着锂离子二次电池的日益普及,关于锂离子电池电极材料的研究也越来越得到重视,传统的碳负极材料因其低比容量已经无法满足新一代锂离子电池负极材料的需要,非碳负极材料的开发研究显得更加重要。本文针对锌基材料具有较高的贮锂容量,采用一步水热法制备了纳米ZnS-GNS-CNT负极材料,并采用XRD、SEM等测试手段分析了材料的微观结构和表面形貌;通过循环伏安（CV）、恒流充放电等技术测试了其电化学性能;阐明了硫化锌材料的嵌脱锂机理,100次充放电循环后脱锂容量仍有800m Ah g^-1、保持率达75%。纳米ZnS-GNS-CNT材料显示出较高的比容量和优秀的循环性能,是有潜力的锂离子电池负极材料之一[1-2]。更多还原

【Abstract】 In this paper, we focused on the studies of Zinc-basedmaterials used as anode materials for lithium ion batteries.The microscopic structure and surface morphology of theprepared Zn S-Graphene Carbon Nanotube Nanocomposite were analyzed by XRD and SEM.Electrochemical properties of the material were measured bycharge-discharge test and cyclic voltammetry(CV).After 100 cycles, the reversible capacity was still maintainedat 800 mA hg-1, 75% of the initial capacity. The Zn S-Graphene Carbon Nanotube materialshowed a high capacity and excellent cycling stability, which was provedto be a promising anode material for lithium-ion batteries.更多还原
