Abstract

A unique architecture with yolk-shell Fe2O3 ⊙ C composites attached to the surface of MWNTs is designed. Benefiting from the good electrical conductivity of MWNTs and carbon layers, as well as the large void space to accommodate the volume expansion/extraction of Fe2O3 during battery cycling, the obtained MWNT@Fe2O3 ⊙ C exhibited outstanding lithium and sodium storage performance.

摘要

设计了一种独特的结构，其中蛋黄壳型Fe2O3⊙C复合材料附着在多壁碳纳米管（MWNTs）表面。得益于多壁碳纳米管和碳层良好的导电性，以及在电池循环过程中可容纳Fe2O3体积膨胀/收缩的大空隙空间，所制备的MWNT@Fe2O3⊙C表现出优异的锂和钠存储性能。
