Fabrication of Si Nanoparticles Encapsulated into Porous N-Doped Carbon for Superior Lithium Storage Performances

Si/FeSi2 Nanoparticles Prepared by Thermal Plasma with Stress‐releasing Effect for Li‐ion Storage

“…The lithiation process of Si causes increase stress on the outer surface of the Si particles, leading to breakage of silicon particles, thick solid electrolyte interphase (SEI) layer overgrowth, and drastic capacity reduction [7] . Besides, poor conductivity and low coulombic efficiency also limit their practical applications [8] . Especially, the continuous SEI formation leads to continuous consumption of active lithium and electrolyte, which is also a major challenge for LIBs [9–11] …”
