Silicon is a promising anode material for the increased performance of lithium-ion batteries because of its high elemental composition and specific capacity. The application of silicon on a commercial scale is restricted due to the limitation of volume expansion.
Inspired by the possibilities of value-added of this raw material, we propose the facile preparation of silicon/carbon nanocomposites using carbon-coated silicon nanoparticles (<100 nm) and a petroleum pitch as anode materials for Li-ion batteries.

Schematic representations of lithiation/delithiation of silicon particles using conventional binder a and the SHPET binder b Although silicon-based materials have a large specific capacity, they have not yet been widely used in lithium-ion batteries. The main reason is that the large volume change of silicon leads to poor cycle performance.
