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. In this regard, Electrochemical prelithiation process can be regarded as an enabling approach to eliminate the large first capacity loss (almost by ~60%) of MWCNTscontaining Silicon-rich Silicon/Graphite anode. In contrast, a benchmark anode using Carbon black (Super P) demonstrated a reduction of ~47% after prelithiation, which is considerably smaller compared to MWCNTs-based system. Furthermore, cycling performance and the Initial Coulombic Efficiency have been enhanced by prelithiation, demonstrating a major impact onMCWNTs compared to Super P-based design.
