Sn@CNT and Sn@C@CNT nanostructures for superior reversible lithium ion storage

Wang, Yong, Wu, Minghong, Jiao, Zheng, Lee, Jim Yang·2009·Chemistry of Materials

Abstract

In this study we demonstrate a facile templated chemical vapor deposition (CVD) method to produce CNT-encapsulated Sn nanoparticles with ∼100% particle encapsulation and high filling uniformity. The encapsulated Sn particles were formed either as Sn or Sn@carbon core−shell particles with good control of size and morphology. The complete and uniform encapsulation of small, electrochemically active Sn particles within a CNT matrix with large free volume accommodated the volume excursion problem in repetitive lithium insertion and extraction reactions very well, showing good resilience in maintaining electrical connective and mechanical integrity. Consequently the completely filled Sn@CNT nanocomposite showed excellent reversible lithium ion storage properties.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
