Abstract

α-Fe(2)O(3) hollow spheres with sheet-like subunits are synthesized by a facile quasiemulsion-templated method. Glycerol is dispersed in water to form oil-in-water quasiemulsion microdroplets, which serve as soft templates for the deposition of the α-Fe(2)O(3) shell. When tested as anode materials for lithium-ion batteries, these α-Fe(2)O(3) hollow spheres manifest greatly enhanced Li storage properties.

摘要

α-Fe(2)O(3) 空心球具有片状亚单位，通过简便的类乳化剂模板法合成。甘油分散在水中形成油包水类乳化液微滴，作为沉积α-Fe(2)O(3)壳的软模板。将这些α-Fe(2)O(3)空心球用作锂离子电池的阳极材料进行测试时，表现出了大大增强的 Li 存储性能。
