Highly Reversible Lithium Storage in Spheroidal Carbon‐Coated Silicon Nanocomposites as Anodes for Lithium‐Ion Batteries

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.
