<p>Silicon anodes hold substantial potential as alternatives to graphite in the application of lithium-ion batteries (LIBs). Regrettably, pure silicon lacks sufficient structural and electrochemical stability. In this study, silicon, decorated with artificial solid electrolyte (ASE) layer, was successfully synthesized by employing inexpensive micron-sized silicon powder, H₂O₂, and CH₃COOLi·2H₂O, followed by low-temperature sintering. The synthesis process is both environmentally benign and safe. The ASE layer acts as a robust protective coating, effectively restricting the lithiation degree and volume variation during cycling, ultimately boosting electrochemical performance. At 0.5 A g⁻¹, 80.0% of the capacity was retained over 200 cycles, and a specific capacity of 774 mAh g⁻¹ was achieved at 5.0 A g⁻¹. The ASE-decorated silicon shows potential as advanced anode materials for LIBs, especially for mass production applications.</p>
