Abstract 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 Fe 2 O 3 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 Fe 2 O 3 uniformly anchored on hierarchical porous carbon-based microscopic structure with a size distribution between 80 and 100 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 327 mAh g −1 after 150 cycles under 200 mA g −1 . When incorporated with rice-like Fe 2 O 3 , the composite delivered a specific capacity of 1094 mAh g −1 after150 cycles at 200 mA g −1 and a high capacity of 765 mAh g −1 even at 1600 mA g −1 .

具有增强锂储存能力的改性竹炭负载的单分散类似米的Fe 2 O 3 简单且价格低廉

摘要 竹炭（BC）具有与洋葱富勒烯碳和碳纳米管相似的结构和性能，具有分级多孔、微孔隧道结构和良好的导电性。通过简单的处理，可以获得具有良好电化学性能的碳基底材料。改性竹炭 (MBC) 负载的单分散米状 Fe 2 O 3 是通过锚定在碳木炭基质上的 FeOOH 的轻松沉淀结合高温煅烧制备的。SEM结果表明，米状Fe 2 O 3 均匀锚定在分级多孔碳基微观结构上，尺寸分布在80-100 nm之间。此外，杂化物作为负极材料表现出良好的储锂性能。MBC表现出稳定的循环性能，在200 mA g -1 下循环150次后，可逆容量仍可保持在327 mAh g -1 。当与类似大米的 Fe 2 O 3 结合时，该复合材料在 200 mA g -1 下循环 150 次后提供 1094 mAh g -1 的比容量，并且即使在 1600 mA g -1 下也提供 765 mAh g -1 的高容量。
