“…In 2022, Ma and co‐workers [ 133 ] continued the idea of inserting a buffer layer between the anode and lithium foil and conducted a more in‐depth study (Figure 3g–m). The researchers used the low‐cost mesophase pitch (γ‐resin) to prepare the intermediate buffer layer.…”

Si-based rechargeable lithium-ion batteries (LIBs) have generated interest as silicon has remarkably high theoretical specific capacity. It is projected that LIBs will meet the increasing need for extensive energy storage systems, electric vehicles, and portable electronics with high energy densities. However, the Si-based LIB has a substantial problem due to the volume cycle variations brought on by Si, which result in severe capacity loss. Making Si-based anodesenabled high-performance LIBs that are easy to utilize requires an understanding of the fading mechanism. Due to its distinct advantage in morphological changes from microscale to nanoscale, even approaching atomic resolution, electron microscopy is one of the most popular methods. Based on operando electron microscopy characterization, the general comprehension of the fading mechanism and the morphology evolution of Si-based LIBs are debated in this review. The current advancements in compositional and structural interpretation for Si-based LIBs using advanced electron microscopy characterization methods are outlined. The future development trends in pertinent silicon materials characterization methods are also highlighted, along with numerous potential research avenues for Si-based LIBs design and characterization.

“…It enabled the construction of an environmental-adaptive prelithiation that could function well even in humid conditions. [38] Li and co-workers developed a roll-to-roll metallurgical prelithiation method using thin Li foil to prepare the lithiated alloy foils. [31,39] By first stacking a thin Li foil (50 µm) on Sn foil (40-100 µm) and then rolling them under ≈30 MPa pressure, the metallurgical prealloying of Li foil and Sn foil occurred (Figure 2e).…”

The ever‐growing market of portable electronics and electric vehicles has spurred extensive research for advanced lithium‐ion batteries (LIBs) with high energy density. High‐capacity alloy‐ and conversion‐type anodes are explored to replace the conventional graphite anode. However, one common issue plaguing these anodes is the large initial capacity loss caused by the solid electrolyte interface formation and other irreversible parasitic reactions, which decrease the total energy density and prevent further market integration. Prelithiation becomes indispensable to compensate for the initial capacity loss, enhance the full cell cycling performance, and bridge the gap between laboratory studies and the practical requirements of advanced LIBs. This review summarizes the various emerging anode and cathode prelithiation techniques, the key barriers, and the corresponding strategies for manufacturing‐compatible and scalable prelithiation. Furthermore, prelithiation as the primary Li+ donor enables the safe assembly of new‐configured “beyond LIBs” (e.g., Li‐ion/S and Li‐ion/O2 batteries) and high power‐density Li‐ion capacitors (LICs). The related progress is also summarized. Finally, perspectives are suggested on the future trend of prelithiation techniques to propel the commercialization of advanced LIBs/LICs.
