Silicon has a high theoretical capacity and a low operating potential, making it a promising anode material for lithium-ion batteries. However, its poor cycle stability and low electrical conductivity remain major challenges, and impurity doping with elements such as boron and phosphorus has been investigated as an approach to improve its electrochemical performance. In this study, boron and phosphorus co-doped silicon nanoparticles with a diameter of approximately 10 nm were applied as anodes for all-solid-state lithium-ion batteries, and the relationship between doping concentration and charge–discharge performance was investigated.
