Highly reversible lithium storage in spheroidal carbon-coated silicon nanocomposites as anodes for lithium-ion batteries

Abstract

(Figure Presented) High-performance cycling: Spray pyrolysis has been used to generate a new type of spheroidal nanosized carbon-coated silicon composite (see TEM image). This nanocomposite shows superior electrochemical cycling properties as an anode material for use in lithium-ion batteries, delivering a reversible capacity of 1489 mA h g-1 after 20 cycles. © 2006 Wiley-VCH Verlag GmbH & Co.
