采用无模板法合成氧化铁,然后通过柱内和柱外结构制备了Fe2O3@polyaniline多级空心球。具有多孔结构的大表面积、快速离子/电子传输和机械完整性的组合使得该材料作为锂离子阳极具有吸引力,显示出优异的上级倍率性能和循环性能。
Hierarchical hollow spheres of Fe2O3@polyaniline are fabricated by template-free synthesis of iron oxides followed by a post in- and exterior construction. A combination of large surface area with porous structure, fast ion/electron transport, and mechanical integrity renders this material attractive as a lithium-ion anode, showing superior rate capability and cycling performance.
