|Title:||Crystalline carbon hollow spheres, crystalline carbon-SnO2 hollow spheres, and crystalline SnO2 hollow spheres: Synthesis and performance in reversible Li-ion storage||Authors:||Wang, Y.
|Issue Date:||7-Mar-2006||Citation:||Wang, Y., Su, F., Lee, J.Y., Zhao, X.S. (2006-03-07). Crystalline carbon hollow spheres, crystalline carbon-SnO2 hollow spheres, and crystalline SnO2 hollow spheres: Synthesis and performance in reversible Li-ion storage. Chemistry of Materials 18 (5) : 1347-1353. ScholarBank@NUS Repository. https://doi.org/10.1021/cm052219o||Abstract:||A few types of crystalline hollow structures, crystalline carbon hollow spheres (750 nm), crystalline carbon hollow spheres with encapsulated or decorated 1-3 nm SnO2 nanoparticles, and crystalline SnO2 hollow spheres (200-300 nm) synthesized by various methods, have been evaluated for reversible Li+ storage. The experimental results showed noticeable improvements in a number of performance areas such as specific capacity, rate capability, and cyclability. The improvements could be attributed to a high degree of crystallinity, which increases the electronic conductivity, and the facile transport of Li ions in a hollow shell with nanoscale thickness, which significantly shortens the solid-state diffusion length. © 2006 American Chemical Society.||Source Title:||Chemistry of Materials||URI:||http://scholarbank.nus.edu.sg/handle/10635/88725||ISSN:||08974756||DOI:||10.1021/cm052219o|
