Multi-Walled Carbon Nanotubes (MWCNTs) have been recognized as a beneficial conductive additive material in Silicon-based anodes owing to their unique characteristics, including high electronic conductivity and the capability to alleviate the volume expansion of lithiated Silicon anode-based battery cells. Nevertheless, both CNTs and Silicon irreversibly consume a high quantity of Li-Ion inventory to form the SEI-layer, leading to a reduction in Coulombic Efficiency, a rapid decline in reversible capacity, and a shorter battery life.

The electrochemical prelithiation process is an effective method to tackle this issue and can be regarded as an enabling approach to improve the cycling performance and Initial Coulombic Efficiency of Silicon-rich Silicon/Graphite blend anode. However, the choice of conductive additive material is crucial in the prelithiation process, with MWCNTs demonstrating superior performance compared to Carbon black (SuperP) in improving the effectiveness of prelithiation for Si/Gr anode.
