In order to examine whether or not a silicon electrode is intrinsically suitable for the high-capacity negative electrode in lithium-ion batteries, 9 – 13 a thin film of silicon formed on copper foil is examined in a lithium cell. Figure 1 shows the charge and discharge curves of a 1000 nm thick silicon electrode examined in a lithium cell.
An application of thin film of silicon on copper foil to the negative electrode in lithium-ion batteries is an option. 10 – 12 However, the weight and volume ratios of copper to silicon become larger, and consequently a high-capacity merit of silicon electrode is spoiled.

However, when silicon is used as a negative electrode material, silicon particles undergo significant volume expansion and contraction (approximately 300%) in the processes of lithiation and delithiation, respectively.
Pitch-based carbon/nano-silicon composites are proposed as a high performance and realistic electrode material of Li-ion battery anodes. Composites are prepared in a simple way by the pyrolysis under argon atmosphere of silicon nanoparticles, obtained by a laser pyrolysis technique, and a low cost carbon source: petroleum pitch.
