Cheap and scalable synthesis of α-Fe2O3 multi-shelled hollow spheres as high-performance anode materials for lithium ion batteries

Chem Commun (Camb). 2013 Oct 7;49(77):8695-7. doi: 10.1039/c3cc43867h.

Abstract

Delicate α-Fe2O3 multi-shelled hollow spheres have been prepared by a simple and scalable spray drying method followed by annealing in air. The resulting material shows high specific capacity, good cycling stability, and excellent rate performance in lithium ion battery applications.
