Abstract
原位电镜技术(In-situElectronMicroscopy)近年来发展迅速,在微纳米尺度的材料研究中发挥巨大作用,特别是能把材料的物性和微观结构直观地一一对应起来,这为深入理解能源存储与转换器件的微观过程提供了强有力的手段钠离子电池是一种应用潜力巨大的二次电池,相比锂离子电池有原料丰富、生产成本低的优点。但是因为钠离子较大的离子直径和较低的荷质比,还需进一步寻找合适的电极材料并探究其工作机理。碳纳米纤维是硬碳材料,石墨化程度低,导电性和机械性能较好,能够快速地嵌入和脱嵌钠离子,是一种优秀的钠离子电池负极材料。静电纺丝法制备纳米纤维因工艺简单、成本低廉、适合大规模生产而受到广泛关注。因此,...
 
As a rapidly developing technique, in-situ electron microscopy plays an important role in the study of micro and nano scale materials due to its unique capability of direct linking, the properties and the microstructures of materials, thus providing a powerful tool for deeper understanding of the mechanism of energy storage and conversion devices. Sodium ion batteries have attracted great interest...
