%X Prelithiation technology has emerged as an enabling approach towards the practical deployment of Silicon negative electrode-based Li-Ion batteries, leading to significant advancement in initial Coulombic efficiency (ICE), energy density and cycle life. In this study, an electrochemical prelithiation has been applied to Multi-Walled Carbon Nanotubes (MWCNTs)-containing Silicon-rich Silicon/Graphite-based negative electrode, eliminating almost ~51.03 % of its first irreversible capacity losses. In contrast, a benchmarking negative electrode utilizing Carbon black (Super P) as conductive additive is found to demonstrate a reduction of ~39.55 % after prelithiation, which is considerably lower compared to MWCNTs-based electrode system. Post-mortem analysis using Energy-dispersive X-ray (EDX) analysis with a Scanning Electron Microscope (SEM) and Attenuated Total Reflection Fourier Transform Infrared Spectroscopy (ATR-FTIR) shows disparities between pristine-cycled and prelithiated-cycled negative electrodes. Overall, prelithiation enabled MWCNTs can be regarded as an essential additive component in Silicon-based negative electrode systems for high-energy density Li-Ion batteries.
