Electrodeposition, Structure and properties of novel Sn-based Alloy anode materials for lithium-ion battery
Get PDF目前商品化的锂离子电池中使用的负极材料是碳材料。信息化技术和便携式电子设备的发展对锂离子电池提出了更高的要求，迫切需要研究更高质量比容量的新型锂离子电池负极材料，其中锡金属及其合金具有较高的比容量，是很有希望取代碳负极材料的候选材料之一。本文介绍了锂离子电池的发展与研究概况。对三维网状Sn电极、多层结构Cu/Sn合金电极以及三维网状Sn-Co合金电极的制备、表征和电化学性能进行了研究。采用电沉积技术制备了平面式和三维网状结构Sn电极，通过充放电和循环伏安实验测试了Sn电极的电化学性能；运用扫描电镜(SEM)观察了电极充放电循环前后的形貌变化；用电化学交流阻抗(EIS)技术分析了不同电位下电极表...At present, the commercial anode material for lithium-ion batteries is carbonaceous material. The information technology and the portable electronic equipment development proposes to the lithium ion battery a higher request, urgently needs to develop new anode material with the higher grade capacity for lithium ion battery. Sn and Sn-based alloys are promising materials to replace carbonaceous mat...学位：理学硕士院系专业：化学化工学院化学系_物理化学(含化学物理)学号：20032507
