采用纳米铸造技术成功地制备了由纳米晶包裹在微米级多孔碳泡沫中的介孔Li 4 Ti 5 O 12/C纳米复合材料。这种介孔Li 4 Ti 5 O 12/C纳米复合材料与体相Li 4 Ti 5 O 12相比具有极高的倍率容量和优异的循环性能。这一重要发现表明，“介观-纳米”复合材料显然是储能的有用候选者，使一类新的锂离子电池能够大规模应用。
A mesoporous Li 4 Ti 5 O 12/C nanocomposite consisting of nanocrystals confined in a micrometer-sized porous carbon foam is successfully fabricated using a nanocasting technique described on page 691 by XG Zhang, GZ Cao, and coworkers. This mesoporous Li 4 Ti 5 O 12/C nanocomposite delivers an exceptionally high rate capacity and excellent cycling performance in comparison to bulk Li 4 Ti 5 O 12. This important finding shows that ‘meso-nano’composites are clearly useful candidates for energy storage, enabling a new class of lithiumion batteries for large-scale applications.
