There is an urgent need to explore novel anode materials for lithium-ion batteries. Silicon (Si), the second-largest element outside of Earth, has an exceptionally high specific capacity (3579 mAh g −1), regarded as an excellent choice for the anode material in high-capacity lithium-ion batteries.
A rigorous examination and refinement of Si-based anode materials are essential steps to enhance the performance of LIBs, particularly in addressing the mechanical instability associated with substantial volume fluctuations in Si during cycling, which can lead to electrode degradation and a reduction in battery capacity [33, 34].
Utilizing the performance and properties of the binary alloys of Li-In and Li-Bi, Mao An et al. developed a composite lithium electrode (Li–Bi–In) incorporating Li–Bi and Li–In alloys as the lithium host to mitigate the dimensional instability observed in lithium anode.
