dc.description.abstract基于转化反应机理的过渡金属氧化物(TMOs)由于具有高的理论容量(≥1000mAh/g)倍受研究者的关注。在众多TMOs中,铁氧化物(Fe3O4和α-Fe2O3)由于低成本,制备工艺简单,无毒且分布广泛等优点,成为新型高容量锂离子电池负极材料的研究热点之一。然而铁氧化物在循环过程中大的体积变化导致颗粒发生粉化碎裂,从集流体上脱落,因此造成循环过程中容量的急剧衰减。本文通过液相法合成具有高分散的Fe3O4/GNS复合材料,通过溶剂热法合成具有特殊形貌的的α-Fe2O3/GNS复合材料,并研究材料形貌结构与电化学性能之间的关系。主要内容如下: 1.采用水热法将Fe3O4与石墨烯进行复合。材料首周...
dc.description.abstractRecently, transition metal oxides (TMOs) based on the reaction mechanism of “conversion reaction” have attracted numerous attentions as anodes materials for lithium ion batteries due to their high specific capacity (≥1000mAh/g). Among TMOs, iron-based oxides (Fe3O4 and α-Fe2O3) were considered as the most promising candidates due to their low cost, resource abundance and environmental friendliness...
