Multi-walled carbon Nanotubes (MWCNTs) are hailed as beneficial conductive agents in Silicon (Si)-based negative electrodes due to their unique features enlisting high electronic conductivity and the ability to offer additional space for accommodating the massive volume expansion of Si during (de-)lithiation.
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.
Silicon (Si) is one of the most promising candidates for application as high-capacity negative electrode (anode) material in lithium ion batteries (LIBs) due to its high specific capacity. However, evoked by huge volume changes upon (de)lithiation, several issues lead to a rather poor electrochemical perform-ance of Si-based LIB cells.
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.
Pure silicon negative electrodes have huge volume expansion effects and SEI membranes (solid electrolyte interface) are easily damaged. Therefore, researchers have improved the performance of negative electrode materials through silicon-carbon composites.
