제목 Synthesis and electrochemical analysis of a-Fe2O3 hollow sphere for lithium ion batteries
초록 α-Fe2O3 hollow spheres with different sizes were prepared through a glycerol emulsion template method, and the carbon coated α-Fe2O3 hollow spheres are obtained by facile hydrothermal method using glucose as anode for lithium ion battery. The carbon coated α-Fe2O3 shows higher discharge capacity of ca. 1800 mAh g-1 than non-carbon coated α-Fe2O3 hollow spheres ca. 1464 mAh g-1 on the first cycle, and also cycling performance, rate capability, and cycling performance were greatly improved by carbon layer. Stability improvement of small-sized α-Fe2O3 hollow spheres by thin carbon can be promising process for advanced high performance anode in lithium batteries.
