Silicon (Si) is recognized as a promising candidate for next-generation lithium-ion batteries (LIBs) owing to its high theoretical specific capacity (~4200 mAh g[sup.−1] ), low working potential (<0.4 V vs. Li/Li[sup.+] ), and abundant reserves. However, several challenges, such as severe volumet...
