- Abstract
- Bulky carbon layer uniformly distributed with nanoscale Fe2O3 was prepared via a direct carbonation of Fe3+-polyacrylonitrile complexes at 700 degrees C under N-2 flow. The iron oxide carbon composites exhibited an excellent cycling performance for lithium storage with a reversible capacity of similar to 810 mAh g(-1) after 250 cycles at a current rate of 100 mA g(-1). The enhancement was mainly attributed to dual functions of bulky carbon layer which facilitated the lithium-ion diffusion and accommodated the volume changes of active Fe2O3 during charge/discharge process. Our novel chemical strategy is quite effective for scalable fabrication of high capacity lithium-storage materials. (C) 2018 The Korean Society of Industrial and Engineering Chemistry.
