چکیده انگلیسی
Bamboo charcoal (BC) shows similar structure and property to the onion fullerene carbon and carbon nanotubes with hierarchical porous, microporous tunnel structure and good electrical conductivity. By simple treatment, a carbon substrate material with good electrochemical properties can be obtained. Monodispersed rice-like Fe2O3 supported by modified bamboo charcoal (MBC) are prepared via a facile precipitation of FeOOH anchored on carbon charcoal substrate combined with a high temperature calcination. The SEM results show that rice-like Fe2O3 uniformly anchored on hierarchical porous carbon-based microscopic structure with a size distribution between 80 and 100â¯nm. In addition, the hybrids exhibit good lithium storage property as anode materials. MBC shows stable cycle performance and the reversible capacity can still be maintained at 327â¯mAhâ¯gâ1 after 150â¯cycles under 200â¯mAâ¯gâ1. When incorporated with rice-like Fe2O3, the composite delivered a specific capacity of 1094â¯mAhâ¯gâ1 after150 cycles at 200â¯mAâ¯gâ1 and a high capacity of 765â¯mAhâ¯gâ1 even at 1600â¯mAâ¯gâ1.
