Silicon possesses a 10-fold specific capacity compared to commonly used carbon-based anodes. The volume instability, among other impediments for practical use of silicon anodes, leads to the rapid decay of the capacity because of poor cyclability. Urgent mechanisms are required to improve lithium-ion storage during cycling and prevent volume …
Without prelithiation, MWCNTs-Si/Gr negative electrode-based battery cell exhibits lower capacity within the first 50 cycles as compared to Super P-Si/Gr negative electrode-based full-cell. This could be due to the formation of an SEI layer and its associated high initial irreversible capacity and low ICE (Figure 3a, Table 2).
